Title: Drying of Shaped Articles with a large Amount of Heat Transfer Medium
Original
Publicat-lon: Ogneupory, 1956, 140 1, 32-34
Abstract: On drying of heavy and intricate chamotte bricks, produced by plastic
ferming, in accordance with conditions specified in the manuals
kmoisture content of heat transfer medium >70% and temperature
^,70mgOO)j a considerable amount of rejects are obtained due to cracks
and flaws caused by drop in moisture over the cross-section of the
art1cle and uneven shrinkage. To prevent rejects drop in moisture
ccntent between surface and center of the article must be minimal,
which requires decreasing of the external and an increase of the In-
ternal diffusion of the moisture. In addition, under the above

TITLE; Spectral and angulq~K distributions of gamma rays from a plane
monodirectional CoDu source, scattered in iron
PERIODICAL: Atomnaya energiya, v. 11, no. 5, 1961, 443-445
TEXT: Angular and energy distributions of gamma quanta scattered in a
plane iron shield were measured by means of a total-absorption spectro-
meter with cylindrical NaI(Tl) 80 mm in height and diameter. The
measuring method is described in Ref.4: Ye. L. Stolyarova et al.
(Apparatuses and methods of radiation analysis), Sbornik nauchnykh rabot
MIFI, no. 3, M., Gosatomizdat, 1961. The results are grap, ically
presented. Fig. 1 shows the energy distribution of the Coto gamma V_K
radiation scattered in a 15.6 am thick iron sheet. This thickness
corresponds to 6 mean free paths. Fig. 2 shows the angular distributions
relative to the intensities of the nonscattered radiation for three
barrier thicknesses. The intensity Of scattered radiation depends ex-
ponentially from the scattering angle: 1(6) = I(O)exp(-B/G .). In a

semilogarithmic coordinate system, the measured intensity values fit the
theoretical straight lines rather well. Fig- 4 shows the angular
dependence of the intensity of the scattered gamma radiation in a solid
angle of 2nsin 8,&G for three barrier thicknesses. The energy build-up
factors were found to be increasing linearly with increasing barrier
thickness IL0x. The theoretical straight line calculated by the Monte-Carlo
method lies somewhat above the experimental one but within the error 1411'
limitsq since the theoretical error amounts torv8%. There are 5 figures

ABSTRACT: The author acknowledges in literature that there are designs for pro-
tective screens for various installations,, but he also noXes that these are
applicd only to the so called standard geometries of radiation sources and protect-
ion media. Fis goal was to investigate the spatial distribution of y rays from
bounded parallel beams scattered in a protective barrier. Previously attained
experimental data on the spectral and angular distribution of scattered -y rays was
the starting point for this work. The dependence of the constant A on the thick-
ness of the protective barrier can be defined.by known faetbis of the Inclination

ABSTRACT: The angular distribution of Y radiation after penetrating through
homogeneous and heterogeneous shielding was Investigated as a function of the
X-ray energy using the experimental arrangement described in Ye. L. Stolyarova
et a]. (Pribory* I metogy* agaliza izi chenly, No- 3, Moscow, Gosatomlzdat, 1962).
The ~_ray sources (Au 9 , Co O.and Na2 ) were either pointlike and isotropic or
planar and unidirectional. Shielding barriers.were made from lead, iron, alumin-
um and combinations of two of these materials. The angular distribution of the
W-rays s a function of energy for a homogeneous material (Pb, ILx 6) can be

TITLE: The problem of protection against electrons and bremsstrahlung from the
outer radiation belt of the Earth
SOURCE: Moscow. Inzh.-fIz. Institut. Voprosy* dozimetril I zashchity* ot

TOPIC TAGS:. radiation belt, cosmi,c radiat-ion radiation protection, beta ray,
bremsstrahlung, space flight, electron stream
ABSTRACT: The aut%ors note that 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 ! 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 new data and analyze the contribution of the electrons

and the bremsstrahlung, respectively, to the over-all dose past the shielding. A
model is proposed for this purpose, based on several simplifying assumption*s (an
isotropic spherical source of bremsstrablung), 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 bremsstrahlung and
other parameters as well. It Is established that the greatest contributions to
the dose intensity of outer belt electron bremsst~ahlung 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/cm2 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/cM2, by far the greatest part of the dose I- due to
alactrons whIch-Penetrate through the shielding; at d > I " 2 g/cmil the dose is
determined ontiraly by bromostrahlung. In concluslom, the AUthord attar GIFtAIM

2)' 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 arte

ABSTRACT- The existing source3 of errors of the rapid methods as well as the
apparatus beloiGing to thein consist, according to the opinion of
the authors, in the fact, that the gas which was eliminated during
the course of experiments carried out, %-ias supposed only to be hy-
drogen, but, in reality, also C02 wrater vapor and GO were existant.
A new apparatus is suggested in this parer which, first of all, per-
mits the elimination and capture of va-por and highly volatile gases
from the sample. The vapor is condensed and the %water obtained is
frozen-in and -..reighed, the captured gases are determined in the sayiie
manner. Next, the products are determined Miich are elimin-ated
in the course of time, In thi3 vray the content of H21 H20 '"a C02
can be determined separately in the sww9le. The apparatus consistB
of a system of quartz tubes, to one end of ahich a tubular furnace

ing measuring devices is located at the other end of the system. In
the system itself the ir-+ercept--on chambers (extensions) for the
capture of vapors and gases including the corresponding measuring
devices are located, as 17ell as a connection vith the spectrograph.
When carrying out the experli;;e-at the fact that part of the condensed
vapor goes over to hydrogen, has to be taken into account, vthioh can
be determined spectrographically. Here it ivas detenninea that, if
the eliminated vapors and gases are not eliminated from the part
in which the heated sample is located, a decrease of vapor elimina-
tion -aith a simultaneo-us increase of forming of hydrogen takes pl~lcc.
