TITLE: Gamma-Ray Radiation Dosimetry Utilizing Changes In
Optical Activity of Certain Hydrocarbons. Letter to the
Editor
PERIODICAL: Atomnaya energlya, 1960, Vol 8, Nr 3, pp 264-265 (USSR)
ABSTRACT: Basic shortcomings of chemical dosimetric methods are
their complicated nature, length of chemical processing
after exposure, nonuniqueness, and low accuracy of
results. The authors investigated radiation effects
on solutions of succhavose and glucose with the aim of
achieving a simple method which would also be sensitive
to very large doses. In the water solutions used, the
dosimetric property is the optical activity which
varies under the influence of Y-radiations. The ChDA
brand of glucose and saccharose was dissolved in
doubly distilled water. 7 ml samples were irradiated
C ard 1/4 by means of 7-rays of Co 60 of 2.100 Curies of activity.

Gamma-Ray Rndiation Dosimetry Utilizing 78333
Changes in Optical Activity of Certain SOV/89-8-3-1-8/32
Hydrocarbons, Letter to the Editor
The largest power used was 1.1 Mr/hr. Optical
activity was measured by means of a sensitive
polarimeter while doses were measured using the
ferrosulphate or methylene blue method. Fig. 1 shows
the typical variation of the angle of rotation CL of
the polarization plane in saccharose and glucose
solutions with 45% (curve 1) and 20% (curve 2) concen-
trations. Yieasuring device was 10 cm long. Fig--
ure 2 represents the same relationship but in ins a/ic
units, where I - is the length of the light path and
C the concentration. The simplicity of the investi- 8
,gation after exposure, wide range of doses (up to 10
or 109 r) and independence from the power of the
dose Induced the authors to recommend this method.
Glucose seems to be the better material due to Its
better overall stability. In -case of saccharose, the
variation of angle of rotation is very much dependent
on temperature, and increases very much with the in-
Card 2/4 crease in temperature. There are 3 figures; and 11

TEIT: The investigations dealt with in the present paper were conducted
on the cyclotron of the Loni W adskiy fisiko-tekbuichookiy Inatitut
(Leningrad Institute of PhX&JSM_Az"11KMn1ng.Y). a-partialea with 10-15,
11-5, and 4.3.2 Mov were used for the experimenis. A scattering chamber
of 50 om diameter was connoot*d to the cyclotront and the target was
placed in its center; this was surrounded by photographic platen con-
tained in special boxes. The plates were of the typo 34-2 (Ya-2) with
an emulsion thickness of 100 p. The target consialed of metallic lithium
in natural isotopic composition (0-75 - 1-1 mg1cx4) and was situated in
dry carbon dioxide The latea were evaluated by means of a microscope
of the type "614-3 iXBI-3@; the track lengths were measured, and the

particle groups were determined. The deviation* of the absolute values
of the differential cross sections from the mean values did not exceed
30-40% in the various experiments. Results concerning the angular dis-
tributionx of the various reactions are outlined in the paper under re-
view. Angular distribution of reaction L17(*qa,)Li7* N - - 4.61 NOT):

TEXT: The authors had established in Ref. 1 that the differential cross
sections of the reactions F9(n,d)O"' and p3l (n,d)Si 30 coincide if the
transitions to the ground levels of 0 18 and Si30 take place at'
En - 14-1 Mev. If it is assumed that this is due to the last protons of
F19 and P31 being in the same statev a similar result should be expected
V11"t
for the reactions Ne 20 (n,d)F 19 and S32 (njd)P31, since also in this case
the last protons of Ne 20 and S 32 are in the same state (2S 1/2) . To clear
up this, the authors studied eimultaneously the (Ixyd) reactions on F 19

P312 and S32. For this purpose a new method was used, which is described
in Ref. 19 and which makee possible a better separation of the deuteron
group. The reaction S32 (n,d)P31 was investigated on a target with natu-
ral isotopic composition and the deuteron energg spectrum determined.
Fig. I shows this for an angle of emission of 0 in the laboratory sys-
tem.-Q was found to be equal to (-7.7 1 0.!)Mev@ and the differential
crose section at 0 0 was (20.4 � 1@5)00_ 27 CM2/ateradian. The differen-
tial cross section of the reaction F9(n,d)01" at 0" was found to be
(2-11-4 + 1-1).10-27 cm2/sreradianj and q - (--5.9 4 0.3) Mev. The cross
section of the reaction S32 (nvd)P31 was found to be (21.80.2).10- 27cm2
and Q - (-5.2� 0 ;2)Mev. The deuteron angular distributions of these three,
reactioriLq- for 0-30 are shown in Fig. .2. The reaction cross sections de-
crease rapidly with increasing angles. Finallyp the authors discuss a
calculation of the reduced transition widths according to Butler@s
theory. The angular distributions calculated theoretically agree with
the experimental results for all of the three reactiona at an lnteract@on

TEXT: The filaments investigated here by means of high-precision methods
were produced from molten quartz. Determination of the constants of elasti-
city was carried out by means of torsional oscillations of the filament
sample generated by a magnetic field. Two methods of recording the number
of oscillations were tried out. In the case of one of them, the time
signals of the Tashkentskaya astronomicheskaya observatoriya (Tashkent
Astronomical Observatory) and the zero passages of the light beam
reflected by the mirror of the loop oscilloscope were simultaneously
recorded on the photographic film of a loop oscilloscope. With the other
method, the oscillations per unit time were counted electronically, in

hich case a chronometer was used. The second method was found to be more
:
Xact (error of 0.02%), and by means of this method the main results were
obtained. Measurements were carried out with six radiation doses within
the range of from 81-106 r to 845-106 r. Fig. 1 graphically shows the
values of A G/G calculated from the measurements (G is the modulus of
elasticity in shear) as dependent on the dose. In curve I the linear
deformation has not been considered, whereas in curve II it has. Curve III
shows the change of A 1/1 (1 is the length of the filament). It was found
that the modulus of elasticity in shear increases steadily with an
increase in the dose; with a further increasing dose this increase
becomes less. An increase in the modulus of elasticity by 0.16 + 0.02 %
was found with a dose of 8-10a r. The increase in the modulus of elasticity
is explained by the occurrence of ordered domains in th 'e structure of the
molten quartz. There are I figure and 4 references, 2 of which are Soviet.

TEXT. The author studies the effects which, in the interaction between
y-radiation and electrons with solids, will lead to permanent changes in
their properties. These changes are due to the release of energy in the
solid, causing the formation of, e.g., Frenkell defects. All possible
ways of releasing the energy necessary for the production of defects are
discussed. The new formations observed in the solid are due to secondary
processesp e.g. electrons which have formed as a result of the Compton or
photoeffect in the material. Besides the new formations of ions,
molecules, and radicals, excitation centers are also formed which may
cause catalytic processes or chain reactions. The processes may be

divided into three groups: (1) Primary interaction between quantum and
atom for t - 10-18 see; (2) Secondary processes which lead to the forma-
tion of slow electrons, excitation centers and molecular fragments, and
which last some psec'. (3) Aftereffects which determine the phystal and
chemical properties of the system and which may last a few hours or a few
years. The physical processes comprise electric and optical effects, and
changes in dimensions and mechanical and surface properties. The chemical
processes comprise destruction, formation of radicals, liberation of gasp
and catalytic processes. If a biological substance is irradiated,
biological processes occur which may be considerable at small doses@ In
the radiation physics laboratories of the Institut yadernoy fiziki
(Institute of Nuclear Physics) and of the Fiziko-tekhnicheakiy institut
AN UzSSR (Physicotechnical Institute of the AS Uzbekskaya SSR) a group has
for a number of years been conductirg methodological research studies in
the fields of radiation physics. Amongst other things it was found that
y-irradiation of saccharose and glucose causes quite a considerable
change in optical activity. Radiation effects are especially strong in
semiconductors, those in Ge and Si being well-known. In CdS a large
number of excitation centers are formed which disappear on IR-irradiation.

TEXT: The activation of CdS single crystals by X-rays, the migration of
excited centers, and the deactivation of single crystals were studied. A
steady current is quickly established if a single crystal is irradiated
with a broad X-ray beam. This is due to uniform distribution of carrier
and activation centers throughout.the crystal. Irradiation of a local
zone in the crystal center causes a slow current variation which largely
depends on the previous history of the crystal: (1) If the crystal is
pretreated with a broad X-ray beam, the current passing through the crys-
tal quickly reaches its steady value; (2) If the crystal is not first
irradiated, conductivity increases slowly in the course of some tens of

hours. At the beginning of X-irradiation, the weak roentgenoluminescence
of some crystals caused a nearly inertial-free increase in the current
passing through the single crystal when a voltage of 300 v was applied,
This is due to the extinction of roentgenoluminescence by the electric
field, which produces a narrower probe characteristic, The activation
centers exist for several hours and migrate into the crystal. Since the
electric field shows no essential effect on the migration of activation
centers, they are bound to be electrically neutral. The activation level
rises with the dose of local X-irradiation. If the excitation is suffi-
cient the centers produce new ones while moving. The current in
X-irradiation increases even more rapidly as the activation level rises.
The excitation produced by irradiation can either be thermally extinguished
or by exposure to infrared rays. The extinction is accelerated with in-
creasing temperature. Equilibrium between the generation and annealing
of activation centers is established even at 60 - 90 OC. At -1500C, the
crystal is no longer activated by irradiation. A discussion of results
reveals that the activation is primarily caused by atomic diffusion within
the crystal. Estimation of the rate of this kind of diffusion shows that

TEXT. Radiation effects in sugar and glucose solutions were investictated
in the dose range 0-200 million roentgens. The coefficient of optical activity
was monitored'by means of a sensitive polarimeter. Results showed that the angle
of rotation of the polarization plane decreases linearly with irradiation dose.
The effect of concentration incident to this variation of the specific rotation
was investigated. Glucose solutions are recommended as dosimetric liquids in view
of their long preservability, the constanay@of the changes that take place in them
and their insensitivity to temperature.

tive index (nD = 1.5011 � 0.0001), and then it was poured into glass
ampouls and irradiated with a Co 6o source. Initially colorless, it turns
yellow at 5-106 r. With higher doses, insoluble yellowy-white precipi-
tates are formed which can be removed by centrifuging. According to

benzene luminesces bright green-blue. The luminescence was excited by an
Hg lamp wit4 Y(IC-4 (UPS-4) filter. The initial preparation showed no
luminescen6e''in the visible range@ Intensity of luminescence increased
with the dose increasing from 0.6 to-16-10 6 r. At the same time, maximum
intensity shifts to the longwave range. The behavior of irradiated
benzene is similar to that of diphenyl polyene. This suggests
polymerization during irradiation. There are 2 figures and 7 references:

TEXT: On crystalline quartz from Pamir, Volynskaya oblast, (Volyn
oblast') and from Ferganskaya dolina (Fergana valley) the authors studied
the decay of phosphorescence excited by gamma rays, and the effect of
electric treatment, heating, and ultraviolet light on phenomena connected
with phosphorescence. They used a Co 60 source with a radiation
efficiency of 10 6 r/hr. The decay of phosphorescence does not follow an
exponential law, and differs for quartzes of different origin. All gamma-
irradiated quartz samples capable of coloration phosphoresced a few
minutes after gamma irradiation. The more intensively blackened parts
phosphoresced more strongly after gamma irradiation. Crystalline quartz
plates were placed between carbon electrodes. Electric current (6oo v,

400 - 5000C) was passed along the principal optical axis for 10 hrs.
After cooling to room tempera@ure, the samples were irradiated for one
hour. The phosphorescence of the crystal plates changed considerably.
Irradiation of gamma-irradiated samples with ultraviolet light produced
new phosphorescence in those crystals which had phosphoresced after gamma
irradiation. In the electrically treated samples no phosphorescence was
observed after irradiation with ultraviolet light. These results are ex-
plained according to V, L. Levshin (Izv. AN SSSR, ser. fiz. nauk, 2, 3,
1948, p. 277); The energy of absorbed radiation lifts electrons into the
conductivity band. Electrons entering the conductivity band pass into
their normal state due to emission of light or heat energy. They are
partly trapped on shallow localization levels. They can be thermally ex-
cited on these levels, thus causing the second phosphorescence. Insamples
heated to 4000C, all electrons are localized on trapping levels. In the
course of geological periods, electrons pass over to the valence band,
making it impossible to produce phosphorescence on natural quartz by ultra-
violet light. There are 4 figures and 9 references: 5 Soviet and 4 non-

120 hr. Activity was measured on a 5-2(B-2) apparatus, The adsorption of
complex cobalt ions on silica gel was found to increase with concentration
of the solution during irradiation. There was a tendency for the same state
of equilibrium to be established in irradiated samples after irradiation as
in those which had not been irradiated. The color change of silica gel
during irradiation indicates that the ions here adsorbed during irradiation
are of a different composition than under usual conditions. This is attrib-
uted to the establishment of new ion equilibrium during irradiation. The
absorption spectra of the irradiated solutions shift toward the long wave
side@ It is suggested that the ions absorhed by the silica gel during
irradiation contain no structurally bound water. The ion composition also
changes when the silica gel is irradiated after adsorption. The stability
of cobalt ammoniate solutions decreases during irradiation. Processes were
observed, similar to those in a thermal treatment (formation of cobalt
hydrates). When dry silica gel is irradiated without an adsorbent, the
adsorption of complex compounds does not change@ There are 3 figures and 6

TITLEi Effect of gamma radiation on the linear dimensions of
specimens of molten quartz and seignette salt
PERIODICAL: Akademiya nauk Uzbekskoy SSR. Izvestiya. Seriya fiziko-
matematicheskikh nauk, no- 3, 1961, 83 - 85
TEXT: Molten quartz and seignette salt are widely used in scientific
studies; their radiation stability is still insufficiently investigated.
In this connection the authors present data on the change of the linear
dimensions of specimens of these substances caused by gamma irradiation.
The samples were irradiated from water-shielded Co 60 source (2000-curies
activity) with a dose rate of 109 r/hr. The linear dimensions of the
molcen quartz specimen were determined by mefts of a microscope of the
type An-21 (UIM-21) warranting an accuracy of 10-3%; First, an expansion
of the specimen is observed. The maximum of relative elongation is

however, decreases further and, only in the range of (260 - 360) 10 r,
size remains almost constant. The change o- the linear dimensions of
seignette salt were studied by a device of the type 1438-1 (IZV-1)
(accuracy 0.001 mm). Plates cut in two different directions straight and
oblique were studied; in both cases, a linear increase of A 1/1 was obseived
beginning at doses of about 50,106r. The two kinds of plates differed
in the following: In the oblique onesy 41/1 increased in the same way
in direction a and in direction b at increasing dose; in the straight-
cut ones, the relative extension in direction a was considerably less
than in direction b. The inclination of the straight line in the latter
case almost agree with that obtained for oblique cut. The anisotropy
entails a decrease in mechanical strength leading to the decay of the
specimen at (150 - 160).106r. The authors further studied the dependence
of the melting point on gamma irradiation. The following was observed
for seignette salt; from 0 to 40-10 6r the melting point dropped from

74 to 650C, from (40 - 185)-.106r it dropped from 65 to 5300. The two
sections of the curve ran linearly. In seignette salt a seperation of
gas can be observed already at relatively low doses. The corresponding
studies were made in a vacuum chamber (10-3 MM Hg), the separation of
gas was determined manometrically (error 0.05 mm Hg); recording was made
by a device of the type 31TBIW-14 (EPVI-14) and was checked by a device
of the type BT-2 (VT-2). Irradiation was made with a dose rate of 103 r/hr.
In the range 0.6 - 6.6-105r, gas separation increased linearly wiih the
dose. At (40 - 50)110 6r, the curves showed a break. V. A. Yurin is
mentioned. There are 4 figures and 5 references: 3 Soviet-bloc and
2 non-Soviet-bloo. The reference to the English-language publication

TEXT: Experiments showed that, upon gamma irradiation, the microhardness

5-10 7 r, causes a relative change A H/H in microhardness of -35%, a dose
of 5*10 7 _ 12,107 r of -600A. The authors also studied the change of the
melting temperature of Rochelle salt in air under the action of a gamma
irradiation. Figs. 2a and 2b show the temperature change as a function of
the heating time, at a heating rate of 20C/min. The three sections of the
melting curves (steep - flat - steep) correspond to the phases of the salt
/solid - melting - liquid). Fig. 3 shows the change of the temperature

specimens at individual spots, a rupture of the chains, deformation of
the rings, and different kinds of uncontrollable distortions occurred,
whereby a non-equilibrium state in the 4ruoture.of the thread was-caused.
As is shown by the experimental results, G is increased.by gamma
irradiation, 'while Q is decreased. This correspon'ds,.as it were, to the,
transition to a more equilibrated, crystalline state of the substance.
Accordingly, the authors assume that the penetrating radiation compensates,
all possible distortions in glass-like selenium and, thus, arranges its
e'tructure.. There are 2 figures and 2 Soviet-bloc references.

showed that equilibrium pressure is established after a certain time interval,
i.e., the adsorption is not instantaneous. The data indicate that to a first
approximation the additional active adsorption centers produced bythe Y rays
obey the same laWB as ordinary centers on silica gel. The property of silica
gels to thus increase their adsorptive capacity was utilized for the creation
of a greater vacuum in Dewar flasks and'thermos bottles. Tests showed that the
rate of cooling of hot water in pre-irradiated thermos-bottles containing a'
silica gel compartment was slower, and after 20 hr. the temperature of the water
was 5 to 80 higher than in nonirradiated bottles. Orig. art. has: I figureso

(0-33 x 1 r/hour) and changes in their mUgnetic susceptibilities,
W, were measured. The chan6e in X was taken to be proportional to
the change in the force acting on a sample in a nonuniform magnetic
field of 104 oe. The force was measured with analytic balances
BA-ZOO (VA-200) to within 0.02 mg. The susceptibilities of BaCl,
KIO NaCl and KBnO 4 were not affected by irradiation. The diamagnetic

the paramagnetic susceptibility increased to the stray ferromagnet-
ism of radiation defects, while in Co,O and CoOW1 the paramagnetic

susceptibility decreased because of compensation of the sublattice
magnetization by radintion-excited 0 and Gl atoms. In CuM the d-*La:--
magnetic 3UBCpetibility decreased in air (but.not in vacuum) owing
to the formation of paramagnetic centers in tht@ form of CuG1 29 or
CuO and GUOC1. The diamagnetic moment of CaO, ['41-0 BaO and ZnO in-
creased after irradiation owing to impurity oxygen formed by radio-
lysis, which strongly affected the electronic properties of these

T-LEXT: Pactory-made silica gel of XCV (KSK) grade was heat-treated
in evacuated ampoules and thEn subjected to d- rays at dose rates up
to 340,000 r/hour. Adsorption was thcrL investigated by admitting a
gas or vapor to the ampoules held at temperatures from +200C to 11-
quid-nitrogen temperature. On cooling, the adsorption ability of
silica gel increased even without irradiation, but rrays intensi_
Tied this increase. The amount of oxygen adsorbed rose linearly
with pressure of the admitted gas or vapor in unirradiated and ir-
radiated silica gel, indicating the same nature of adsorption cen;.-

ters in both cases. Tile silica gel surf ce became saturated with ad-
sorption centers at doses of 2 - 3 x 109 r. Gamma irradiation raised
the amount of heptane va;jor that could be adsorbed on silica gel
(this effect %,.,as S!:Mllor th,1n for tile majority of gases) but made no
d-ifference to the adsorption of benzene vapor. Irradiation of aque-
ous Bolutions of ammines of the LCo(NH 3)6]C'3 type in direct co@tact
with silica rel raised the ariount of liquid adsorbed because of ra-
diation-induc"ed chemiqal reactions in the solutions rather than due
to changes on tile Silica 6el Surface. Gamma-ir.-adiatioi--. raised a-so
the amounts of oxygen and hydrogen that could be adsorbed by alu-
minosilica rel. A oractical application of these observations con-
b
sisted of Placing Cactiv_ated silica gel between the %-,,ails of a
thermos flask. This improved the vacuum between these walls, by ad-
sorbin,- more gas than UnirradJated silica gel, and thus reduced
heat transmsiion through the walls. Such thermos flasks were pre-

TEXT: In continuation of earlier work on the radiolysis of benzene-
(DAN SSSR, 129, 307, (1959)), mol,3cular optics and spectroscopic
methods were used;to determine the initial stages of the forma-
tion of a polymeric product resulting from the irradiation of ben-
zene. The scattered light method was used, measuring the variations L/
in the degree of depolarization (,@) and in the intensities of the
olarized components of scattered light as the dose was increased
r irradiation, 76 - 543 r/sec). This method proved the most sen-
f
sitive. For unevacuated samples & @ecreased linearly with increas-
ing dose, from -0-42 at 0.075 x 100 r to 0.25 at -0-95 x 106 r;

the isotropic component of the scattered light (I isotropic) in-
creased, while I anisotropic 'remained essentially constant. These
effects were amplified by freezing the samples imr..ediately after
irradiation. The decrease of A was less pronouncbd in degassed sam-
ples, showing that a lesser amount of the polymer is precipitated
under these conditions. Irradiation of unevacuated samples with
ultraviolet (5 1/2 hours) gave results analogous to those of r ir-
radiation. With higher-amounts of the radiolysis produc-lu-s (doses
-107 r), the reactions may be followed by spectroscopic methods.
Luminescence spectra may be used to detect an increase in the mole-
cular weight, i.e. tile formation of the polymeric product when ben-
zene is irradiated. dith low dosages of a' rays 0 x 10 5 r) and under
