TITLEs Radiation of a Cylindrical Source Behind a Plans Shield
PERIODICAL: ktomnaya energiya, 1960, Vol. 8,11o. 4, pp. 374-376
TEXTs The traditional description of radiation absorption of a
cylindrical source is not satisfactory. A better solution of the problem
of gamma radiation absorption is obtained by using-the formula for the
dose rate P - 2PTqR S(ppkqLjRj/A2d) B(pl) where Pa. is a constant, q the
specific activity, z,R,k,p the geometrical dimensions of the cylinder,
/11 is the coefficient of radiation absorption in the s6urce,/L. that of
the protective shield, B the dosage build-up factor for a point BOUrCe.
The integral 5 was computed by means of the electronic computer "Strela".
The values of the integral 5 at p, R - 1 for p - 1-5 Ll 5P,"2 d - 0-5 1. 10
and k - 0.5 and 1.0 are given in the table. In Fig, 2 the computed and

TITLE: The problem of protection against electrons and bremsstrahlung from the
outer radiation belt of the Earth
SOURCE: Moscow. Inzh.-fiz. institut. Voprosy* doximetril I zashchity* ot
izIucheniy (Problems of dosimetry and radiation protection), no. 2, 1963, 100-108
TOPIC TAGS:. radiation belt, cosmi.c radiation, radiation protection, beta ray,
bremsstrahlung, space flight, electron stream
ABSTRACT; The aufhors note't~at in .recent times information on full electron
streams and spectrum in the Ehrth's outer radiation belt has undergone considerable
modification. It has been found that previous estimates of the full electron
streams in the outer radiation belt, based on radiation-counter tests, were ap-
proximately 1,000 times too high. The purpose of the present article Is to re-
view problems of protection against the electrons and bremsstrahlung of' the outer
radiation belt in the light of the new information available with respect to the
streams and the spectrum of the electrons. The authors consider the radiation
hazard to the astronaut (and, concomitantly, the shielding requirements of the
capsule) in terms of the now dati and analyze the contribution of the olectrons

and the bremsstrahlung, respectively, to the over-all dose past the shielding. A
model is proposed for this purpose, based on several simplifying assumptions (an
isotropic spherical source of bremsstrahlung), and an equation is written for the
Intensity of the dose in the center of the cabin. Tables are given, showing the
relative contributions of various spectral components of the bremsstrahlun '9 and
other parameters as well. it is established that the greatest contributions to
the dose intensity of outer belt electron bremisstrahlung are made by electrons
with energies of 0.05-0.3 Mev. The data presented refer to a space-capsule wall
constructed of a material with thickness d - 0.1-10 9/cmz and atomic number Z (in
the particular case of carbon Z = 6, but the data may easily be extrapolated to
other light substances by multiplying the values given by Zeff/6). in the pecond
section of the article, the estimates derived for the bremsstrahlung doses are
supplemented by a calculation of the doses of penetrAting electrons of the outer
belt. The author establishes the fact that the intensity of the electron dose
decays very rapidly as the thickness of the shielding increases. With a shielding
thickness of d < 1.0 9/cm2l by far the greatest part of the dose I due to
olectrons which7panetrate through the shielding; at d > I - 2 g/cm the dose is
determ1nod entiroly by bromistrahlung. In conclusion, the luthoro offer certain
practical considerations with respect to radiation protection In the outer belt,
emphasizing two fundamental -requirements: 1) for reduced bremsstrahlung genera-
tign, the shielding must be manufactured of a material with-a low atomic number;
Card 2/3

ACCESSION NAI AT4021251
ZY for increased bremsstrahlung absorption, the shielding must be manufactured of
a material with a high atomic number. The authors note that these conditions are
satisfied by a combined shielding, consisting, for example, of a layer of low-Z
material (outer layer) and a layer of-high-Z material (inner layer)* Orige art*

ABSTRACT: Economy of weight in spacecraft shielding..is best achieved by placing
the shielding as close as possible to the cosmonaut. Local shielding is
designed taldng into account the varying radios ensitivity of different body
organs and the considerable unevenness of the radiation field inside the
spacecraft cabin. Calculation of local shielding is based on determination
of the effectiveness of shielding of an organ by parts of the ship and by
other parts of the Pody. A model of a so-called standard.man (with typical.

placement of organs) was used to facilitate dose calculations for individual
vital organs. Spatial distributions of tissue thicImesses with respect to
the vital organs were determined using this model. On the basis of data
obtained, calculations were made of doses from a solar flare for various
critical organs, assuming a hypothetical spacecraft hull. Calculations
utiUzed dependences of dose on tissue depth for given shielding thicImesbuo.
Results of these calculations show the definite possibility of weight economy
with the use of local shielding. [W.A. No, 226 ATD Report 66-1161

TEXT: The-rectification of Hg (at atm. pressure
and under vacuum) and of Cd and Zn (vocuum only) was atixdied
in an effort to develop a suitable apparntus for this purpose
and to assess the possibilities of this method for the produc-
tion of very pure metals. A transparent silica column of 18
bubbler-type plates was used for Hg. The apparatus is shown
in Fig. 1.. Both this, and a similar 10-pl-tte column allowed
suf:cessful rectification to be cnrried out; the collecting
rates varied. e.g. from 3.7 to 28.0 g distilled Hg per minute.
Regulation of the amount of reflux was difficult. Apparatus of
basically the same construction was used for Cd and Za, with a
10-plate column, with equally successful')results. It is concluded
Card 1/4

S/080/63/036/001/005/026

that for columns up to 80 mm in dia, the plate separation, 5, is
sufficient when S = (3 + 5) h [6ic*] where h is the thickness of
metal on each plate. Changes in the linear velocity of the vapor
along the column are calculated and found to increase from 1.44
at plate 1 to 11.4 m/sec on rAnte 9. The velocity increased sharply
from plate to plate, tbo increments becoming greater towards the
top of the column. bubbling on the plates is an essential though
not the only condition for successful purification on,columne of
this type. There are 5 figures and 2 tables'.

PERIODICAL: Avtomaticheskaya svarka, no. 1, 1962i 1-6
TEXT: Information is given on a new steel grade, 170_Mq~A WKh-GVEFA),
suggested as a substitute for 25X3HM (25Kh31M) steel used for columns of
chemical apparatus working at up to 320 atm steam pressure at 150-3000C.
Such columns are fabricated from 90-150 mm thick forged steel by electro-
slag welding. The 25Kh3NM steel contains up to 2% nickel, and the required
hardening with subsequent high tempering to sorbite is not possible at most
Soviet plants. The 17Kh3GMFA steel is nickelfree, has a low cooper content,
and is easier to weld because of its low carbon content. The composition
of l7Xh3GMFA is as follows (in %):- 0-14-0.20 C, 0.17-0-37 Si, 1-5-1-6 lLnt

TITLE: Electro-slag welding technology for l7GKh3MFA steel
PERIODICAL: Avtomaticheskaya svarka, no.2, 1962, 44-48
TEXT: Recommendations are given for electro-slag welding 150 mm thick
l7rX3H*l7Gh13MFA) steel sections for hot columns used in the chemical
industry. Information on the l7GKh3MFA steel and requirements as to the base
and weld mtal of hot columns were given in a previous article by the authors
(Ref.l: "Avton-iticheska)-a svarka",No.1, 1962). The process stages are:
(1) Assembling and electro-slag welding the elements of preliminarily annealed
17GKh3MFA steel; -(2) Intermediate annealing of the welded column, and finally
heat treatment as prescribed for the base metal. The chemical composition of
the l7GKh3MFA steel and recommended X5 ?j (Kh5M) welding wire is (Table 1):

Additional alloying of welds was achieved by increasing the portion of base
metal in the welds. The following process details are recommended for 150 mm
thick metal: 26-30 mm gap between edges; alternating current; 45-50 Mn deep
slag Pool; AN-8 (AN-8) ilux; two electrodes; 60-70 nmi long dry electrode throat;
welding wire feed of 220 m/hr (at 450-475 amp current); voltage of 48-50 v;
70 mm space between the electrodes; transverse motion of electrodes at 39 m1hr.

Welded specimens of 100 x 150 x 190 mm size were subjected to the following
heat treatment: normalization with heating to 9 0- O*C, holding for 4 hrs and
cooling at 1000/hr, tempering by heating to 700- O*C, holding for 4h~s and
furnace cooling at 50*Ar. The cooling technique after normalization and high
tempering corresponds to the recomendations of TsNIITmash. Conclusions:
(1) The recommended technique (Kh5M wire, AN-8 flux, 50-55% of base metal in
the weld metal) ensures sound welded joints without flaws. (2) The weld metal
and the heat-affected metal at the welds in the as-welded state have an
acicular tmostite structure with a hardness of 380-400HV. Therefore,high
tempering or annealing must be used directly after welding, before the metal
cools-down completely, and this must be done regardless of the final heat
treatment. (3) After normalization and tempering, the strength, plasticity
and toughness of the weld metal and heat-affected zone fully meet the technical
requirements. (4) The weld metal has no tendency to hot embrittlement in long
holding at up to 3700C. (5) Normalization and high tempering ensure a
sufficiently uniform metal structure in welded joints, and this in combination
with high Cr content in the weld and base metal seems to result in a high

ABSTRACT: The peculiarities of re crystallization were studied and a thermal
treatment was developed for the purpose of restoring the properties of the weld-
affected metal in electroslag welds. The weld-affected zone within 1. 5-2 mm
from the metal-fusion border in welds between 2OKh3MVF 240-mm-thick plate
and 30GKh2MF 285-mm--thick plate was investigated. It was found that a single'-

did not produce any substantial change in the overheated zone of 20Kh3MVF. A
double thermal treatment, at 930 and 980C, resulted in much better toughness in
both steels; this treatment is recommended for electroslag-%ielded parts made
from the above steels. Orig. art. has: 7 figures and 5 tables.

ABSTRACT: The steals referred to are used extensively d~ie to
their resistance to the effect of acids, scale resistancelvand als4D
heat resistance. During the process of manufacture of cold rolled
or drawn tubes made of austenitia and ferritic steels, difficulties
arise which are due to changes in the structure and properties of
the metal and which are not always-fully explained. For
elucidating the nature of some of these changes, investigations
were carried out which are described in this paper. The chemical
compositions of the investipted steels were as follows:
Steel Kh25T; 0.1510o C; 0.9% Si; 0.77% Mn; 26.7% Cr; 0.1+% Ni;
0.73% Ti.

Changes in the Structure of Cold Worked Steels lKhl8N9T and
Kh25T during Heating
Prior to cold rolling and cold drawing the blanks were pierced
and rolled in hot rolling stands and subjected to preliminary
tests. After hot rolling the tubes were quenched in water from
1100 and 950 OC respectively. Following that, the tubes were cold
rolled or cold drawn with maximum degrees of deformation so as to
obtain clearly pronounced textures. The reductions were 75% for
the steel IKhl8N9T and 95% for the steel Kh25T. From the tubes
20 x 20 mm specimens were-cut which were heated to 400, 5oo, 6oo,
700 and 800 OC and held at each temperature for durations of 1,
5~ 25, 50 and 1.00 hours. The structural transformations were
studied by hardness measurements, microstructure study with an
optical microscope, static metallography and X-ray structural
anal7sis,. The results of the changes in hardness and stretching
of the grains in cold drawn and cold rolled tubes from the two
steels are entered in Figs 1 and 2, and 3 and )+, respectively.
The results show that quenched and cold worked austenite of the
steel lKhl8N9T is more inclined to develop phase transformations
leading to an increase in hardness than annealed and cold deformed
austenite which is characterised by a greater stability.

Changes in the Structure of Cold Worked Steels lKhl8N9T and
Kh25T during Heating
Although the general relations remain the same, comparison of the
graphs in Figs 39 4 with those in Figs 1, 2, lead to the
conclusion that In the steel Kh25T the transformations are
considerably slower than in the steel lKhl8N9T. It is possible
that this is due not only to the differing nature of the forming
phases, but also to a generally lower level of type II distortions
in the ferritic steel than in the more strongly work-hardened
austenitic steel. The experimentally established martensitic
transformation in the steel lKhl8N9T and the formation of a
a phase in the steel Kh25T during repeated heating of cold worked
specimens lead to a further conclusion relating to the influence
of the accumulated deformation energy on the distribution of the
individual elements in the solid solution. The determined
transformations in both these steels could not occur in the
equilibrium state. Such occurrence is made possible in the
temperature range 44D0-600 OC by a redistribution of the elements
which leads to a lowering of the solid solution and formation of
