TEXT: Contemporary research on the abscrption of radiation by
the
atmosphere in the close infra-red region of the spectrum is
rev:Ie-
wed. Quantitative charactexistics are gdven for the absorption
of
radiation by water vapor and carbon dioxide in the wavelength
range
from approximately CI-94 -~ for the absorption band of water
vapor to
about 15 1i for the ELbsorptlon band of carbon dioxideL, The
question //7
of taking into account the dependence of absorption on the
pressure
is discussed. 36 references. LAbstractoils note: Complete

TEXT: The aizn of the work is the construction of a scheme
for calculating shortwave radiation flows in the 0 29 - 4F,
spectral region in a layer with a height of up to ~O km. It is
.,uestion of calculating 11pyranometric" flows at different -e-
a a
vels for a cloudless atmosphere. The actual atmosphere is con-
sidered as a superimposition of a molecular atmosphere of set
composition on an aeroso). atmosphere. The following nodel is
taken for the dispersion coefficient on aerosol particles:

TEXT: The author estimated the accuracy of the approximate
method,,
proposed by V. V. Sobolev, for calculating the atmospheric haze
brightness by comparing the computations f:~om this method with
the
tables of the Institut fizi%-.i atmosfery (Institute of
Atmospheric
Physics), obtained by means of the numerical estimation of haze.
A two-layer model of the actual atmosphere, with L. Foytsik's and
Kh. Tsshayek's indicatrices of scattering, is studied. It is
shown
that for a not. too elongated indicatrix the error in Sobolev's
me-

ther discussed the mechanism of the so-called "solai- rain" and
the rate of
hydrogen accretion during the interaction of the so*.'ar wind
plasma with
the terrestrial magneto:ipliere. In effect, they computed the rate
of H 20
molecule formation In the upper layers of the atmosphere from
hydrogen
:of solar origio.
N. N. Shefov showed that in the noctilucent cloud zone the inten-
isity of the hydroxyl OH emission bands increases at about twice
the
normal rate while noctilucent clouds are developing. On the night
following the appearance of the noctilucent clouds the Oil
emission de-
,creases 2-3 times below its average value, and then returns again
to
its previous level. This effect is a quantitative indiFdtor of the
varia-
tion of the chemical composition of the atmosphere at heights of
about
80 km, as well as of the rate'ol' vertical mixing in thes layers.

measurements of moisture in the stratosphere. Spectroscopic
investiga-
tionE~ conducted in 1964-1965 by spectrophotometric balloo.n
lofted to
heights of 30-32 km,have confirmed that the str-t-at9-s-RhqlLg~ is
comparatively
dry - the mixture ratio is 10-(;/5-10-6 g/g. The authors note that
many
investigators who detect high moisture values in the stratosphere
have
introduced substantial errors in their experiments by not taking
into
account the water vapor adsorbed on the walls of the
spectrometers.\YThe
authors theoretically analyzed the possible strEitification of
water
vapor between 30 and 100 km, taking into consideration the
photochemistry
and the general circulation of the atmosphere. Their work shows
that at
heights of 70-90 km there are sufficient concentrations of water
vapor
to concentrate and form noctilucent clouds.
V. G. FesenLgy noted that on the basis of measurements of the
bright-
nesG of twilight: at symmetrical points of the scilaT vertical in
cases of
.large angles of solar depression it is possible to study the
distribution
of cosmic dust nnd the optical thickness of the layers in which
fiocti-
lucent clouds occur. Ibia contention was confirmed by observations

Using theoretical works. the results of aircraft observations,
searchlight sounding deitai and measurements of the brightness of

made in

and V. K. Pvldm;i*a examined the :Iielght distributJ on
6-f the aerosol coeffi-
lcienC_~f ;~atte'ring in the real atmosphere at different
wavelengths.
Iliese methods permitted the study of aerosols in the
2-200-km height
interval, where the coefficient of scattering changes by
three orders of
mignitude. Observations at different geographic points
and in different
.seasons confirm that very often the maximum of aerosol
concentration is
~at heights of 15-22 km, while the minimum of turb,'Ldity
is at heights of
-25-30 km.- The results of the different experimental
investigations agree.
It is found that the turbidity of the air in layers
higher than 30 km is
!,relatively great. and that the coefficient of
scattering there in the blue
:apectral region is double the molecular coefficient of
scattering. In the
red spectral region thia ratio :reaches 6-7:1. Ronenberg
andothers have
noted that aerosol layers are often encountered at
heights of 42-44 km
and near 70 km.
A. V. Fedynskiy diacussed ithe results of instrument
meago~ements of
water vapor concentrations in the mesosphcte madc: 1,
__-___ t heights

principle of
measuring the heat emisi3ion, froin a heated filament in
the presence of

TEXT: A procedure is given for determining the power
consumption per unit of output (heating) and per kilogram of
evaporated moisture (dry.4ng); a method of determining the unit
power consumption in the furnaces of boilers for power supply;
and also a procedure for calculating the industrial efficiency
and cost. The specific energy consumption and efficiency are
compared for the cases of' pure thermal, pure
high-frequency,and
combined procedures for the cases of drying: yarn on bobbins,
tizatiber, and sheepskins. It is shown that energy
characteristics
are insufficient for objective assessment of the economic
advisability of application to heat treatment because different

processes last for different times, result in products of
different quality, require different amounts of initial
materials,
and take up different amounts of space; they may hinder or
facilitate automation, and so on. An economic criterion is
given for the process of heat treatment; its calculation is
illustrated by an example of various methods of drying timber.
The criterion reflects all the equipment requirements and the
method of heat treatment, with allowance for the cost and
quality of production, in a simple and vivid form. It is,
therefore, recommended as a universal objective economic index.

ABSTRACT: By means or a scintillation vapro, speci.Tometer, the Y
-spectrum of a w*ator-
water, pool-type research reactor was measured. The gamma quanta were
directed from
the active section of the roactor to the spectrometer through a lateral
experimental
chaimel, 100 mm in diamotor tuid 2. 6 m In length. To exclude the
influence of gamma
quanta scattered in the ch9nnel, a lead collimator,' 180 mm in length
with a collimation
aperture diameter of 10 mm, was Inserted In the chimnal. The
spectrometer sensor was
placed behind the concreto shieldirg of the reactor, and the gamma
quanta flow passed
through a 260-mm long collimator of paraffin with bcrron and lead

ABSTRACT: A study or the penetration of fast neutrons through iron
~-nvolved the determination of the relaxation lengths X for neutrons
with an energy greater than 2 Mev. It may be assumed that as the
energy of the fast neutrons approaches, the threshold energy (where
inelastic iron-nuclei scattering begins)~ the relaxation lengths of
the fast neutrons abould increase. The spatial distribution of
neutrons with an energy greater than 1.5 Mev in iron was therefore
measured in a wator-moderated,- water-cooled research reactor in
conditions of a ffisemi-iinfinite" geometi.7. The neutrons were
recorded

by an indium indicator [reaction In (n, n') Inm3. The reaction
thres'..
hold is somewhat reduced with the increasing thickness of the iron
layer due to the attenuation of the neutrons spectrum. The absolute
values of the relaxation length'are somewhat higher than indicated
by the calculations, which is probably due to the differences in the
geometries of the experiments. The increasing relaxation length
with the growing thickness of the iron layer may be explained by the
accumulation of neutrons in the iron with an energy close to the
energy threshold of the inelastic iron nuclei-neutron scattering.
This was verified under the same conditions by measuring the spatial
distribution of neutrons in iron with threshold indicators made of
phosphorus (E 3:Kev) and aluminum (E

ABSTRACT: In the study of the shielding properties of different
materials and their com-
binations, it is important to know the following paruneters:
coefficients of attenuation of
-ray and ne-atron streams of different energies; coefficients of
attenuation of the power
level of r-radiation and fast neutorns; yield and spectrum. of
captured iY-radiatior.; acti-
vation of materials in a neutro ns flux; and deformation of the
X-ray and neutron spectra
in their passage through the material. Since existing equipment
is insufficient for shielding
studies,' the authors built and tested a number of scintillation
counters and dosimeters.
Cardl/3-

:ACCESSION NR: AT4019060
Among those described are a scintillation counter and
spectrometer for the study of the
attenuation of ?-ray flux, consisting of a FEU-11B
photomultiplier with an Nal(T1) crystal
(dialneter and height 40 mm) mounted in a housing lined with
aluminum foil, and a
scintillation neutron counter consisting of a FEU-11B
photomultiplier wifil plastic scin-
tillator of ZnS(Ag) + lucite (diameter 30, height 10 ram).
For neutron energies.2: 2 MeV,
the 4r-ray background is calibrated xvith a Co6O source and
eliminated by the proper bias
in the analyzer. A simil-wr neutron counter can be used as a
monitor. A light guide in
conjunction with a smaller counter is used when the opening
in the shielding is too sinall.
This light guide is made oforganic glass (length 60, diameter
10 mm) and is equipped with
a light collector (Tove, P. A. Rev. of Sci. Inst. 27, 143
(1956)). For neutron energies
between 1 and 10 Mev, a z;Ulbene crystal is used (diameter
30, height 20 mm) equipped
with "lie Y- disc rimination arrangement described by 11. W.
Broch (Rev. Sci Instr. 31,
1063 (1960)). The detection efficiency for neutrons between 1
and 10 Mev is 10 - 2%. For
thernial neutron detection, a FEU-29 or FEU-31
photomultiplier with an L120- 3Si02 glass
scintillator is used. Deteation is based on the reaction M6 +
n-> C( + H3. The sensitivity
of these counters to Araya is calibrated by Zn65 to C060
sources. All-wave-lengt1i neutron
counters are constructed as gas counters (type SNM-15) filled
with BF3 and enclosed in
paraffin, which is lined on the outside with cadmium.
Dosimeters for fast neutrons are

made from plastic scintillal~ors (polystyrene + terphenyl + ROROR)
attached to a FEU-25
photomultiplier. The photomultipli-~ir current is integ~-ated and
amplified by a direct
current amplifier. The maximum sensitivity of this d:)simeter is
0.2ju F/sec per division.
In order to eliminate r-ray backgroimd, the measurements are made
simultaneously with
a;,v -ray dosimeter which is a combination of the plastio and
Inorganic sointillators. A
crysUd of Csl(Tl) (volume 1. 5 cm3) is mounted on the axis of the
plastic crystal (poly-N
styrene + terphenyl + ROROR). Finally, a universal stand for
detection an'd power supply
is described. "The authors thank V.~'M. Isakov, D. L Chupy*rin, A.

variety of test purposes,
the author observes that spectrometers with a
hydroge'n-containing sensor cannot be used
for measurements against a high gamrna-background.. The
single-sensor schitillation
spectrometer, the *scintillator of which contains hydrogen and
boron, and which was proposed
by Marshall (Bull. Amer. Phys. Soc. 1 27, 11 (1952)), is
described in detail and its ad-
vantages are analyzed. it In noted, however, that the duti
necessary to permit the actual
construction of such a spectrometer are lacking inthe available
technical. literature. The
following values in particular, are un1mown: 1) the'efficiency of
the spectrorheter as a

scintillator and the ratio of the hydrogen and boron
concentrations in It; 3) the timd distribu-I

may be calculaied
In the case of both spectrometer types by the random test method

that Is, the
authors consider that all processes of scattering and absorption
occur in the xy

does not differ
essentially from that of the ptane problem. The paper is in two
sections: in the
first-the problem of the computation of the characteristics of a
