TITLEi A Thin Window Scintillation V-40tector
PERIODICAL: Pribory i tekhnika eksperimenta, 1961, No. 1,
Pp. 57 - 6o
TEXTt In portable instruments the a-particle probe is
usually designed so that the working volume is separated
from the source by a thin window. The Soviet end-window
a-cou'nters C!47 - ~ (SAT-7), 't.4~O &$11 (T-80 BFL), etc. and
5cintillatlon a-detectors covered Vith aluminium foil
TAC_C, (Tiss), 1- (P-349-2) ) have the following average
values of window thickness and working volume, respectively:
dl-"- 18 mm of airc eZZ 2 mm of air. In order to improve the
efficiency of Soviet counters the present authors have cal-
designed an
culated corrections for absorption and have
a-probe which is very similar to that reported by Grawes,
Webb and Davis in Ref. 2. The phoaphor was ZnS(Ag) I
(80 mm diameter, 5 mm thick). The phosphor is deposited on
a persptx backing from a water suspension and is bonded to

the perspex backing by dichlorethane. After a drying procedure
the specimen is placed into a special press in which it is
heated to 220 0C and then subjected to a pressure of 150 atm.
for 25 min. The heater is then switched off and the specimen
is cooled under pressure to room temperature. The phosphor is
then coated (by evaporation) with an aluminium film
(40-80 Pg/cm2). This film is then covered by a polystyrene
film which is again coated with aiuminium. The total thickness
of this light screen is 120 ILg/cm aluminium and
30 Ag/cm2 polystyrene. This equivale nt to 1 mm of air. When
the phosphor was illuminated with 1 000 lux,the dark current
of the photomultiplier was increaged by a factor of a few tens.
Dark-current pulses were found not to exceed the discrimination
level against the y- background, Thus the probe can be used
in all normal experiments but it cannot be illuminated directly
by sunlight. The results obtained are summarised as follows.
Scintillation detectors covered with a thin window of the
above type have a good reproducibility (+ 2~i). Detectors

80 mm in diameter and having thin windows equivalent to up
to 6 mm of air were found to be satisfactory. The efficiency
of the scintillators when working in conjunction with the
(FEU-24) photomultiplier was found to be 87% at
5.3 MeV and 73% at 4.5 MeV. The efficiency Is several times
greater than for the commercial counters available in the
Soviet Union. The aluminium coating is sufficiently opaque and
rigid for use in a portable instrument. Acknowledgments are
expressed to M.D. Galanin for intereat in the work, to
O,jk. Suyetov and V.S. Konovalov for help in the preparation
of the detectors and in measurements and to S.A. Fridman,

TITLEx Dependence of the characteristics of a scintillation
cx-particle detector on the granularity of ZnS
PERIODICALi Pribory-i tekhnika eksperimenta, no. 4, 1961,
pp. 52 - 57
TEXTa In a previous paper (Hof. I - this journal, 1961,
no' :0 the present authors have described the technology of
pr;paration of scintillation a-partirle detectors with very
thin windows.. The detectors are usually of the form shown in
FISo 1. In the present paper, the authors report further work
aimed at establishing the optimum size of the ZnS grains. It
was found that the optimum charatteriatita were obtained when
the linear dimensions of the grainswere, of the order of 4 Ii. The
resolution of these detectors is about 10 Aset and the necessary
amplification with a I V threshold ia I - 10. The counting
efficiency for a non-self-absorbing source in the immediate
contact with the dtteetor'is found to be of the order of 90%
for 4 - 6 MeV m-partieles. In other cases the efficiency in

typically of the order of 30% (depending on the thickness of
the source). Comparison with other detectors shows that the
present device compares favourably with the ionization chamber.
It has the advantage that it is tompact and simple to use and
does not require large amplification coefficients or photo-
multiplier supply stability. -The dete-.tors are convenient both
in absolute measurements and as ridiation monitors.

TITLE: D6tormination of the concentration of O-active gases
in air
pZRIODICAL: PriborY I telChnika eksperimenta,L-3, 1962, 71-72
TEXT: A description is given of a counter which can be used
in the continuous control of the concentration of O-active gases
in air and for the determination of the total activity of gases
contained in small volumes. The energy range of the device is
18-400 KeV. The apparatus incorporates the flow ionization chamber
shown in Fig.2. The air is drawn through the hoses at each end.
The sensi ivity of a 14-litre chamber was found*to be
0.7 x 10-A C/litre (tritium), 1.3 x 10-9 C/litre (C1402) and
0.8 x 10-9 C/lItre (Xel33), 1.e. It is possible to measure O-active
contaminations from 0.3 of the "maximum permissible concentration".
The maximum concentrations which can be measured are of the order
of 104 m.p.c. There are 2 figures and 1 table.

corrections for the finit 'a dimensions of the accelerator can be made by
the usual formulas. These estimates of shield thickness take no acbount of
the neutrons due to bremostrahluna. This kind of neutron radiation,
however, depends considerably on the shield structure. It constitutes a
local hazard greater than primary bremsetrahlung only when the concrete
shield contains additional layers heavy metal (> 15 om Pb or 35 cm Fe)-

ABSTRACT; The intake-works dam (on the Dyushambinka River) is designed to
handle a maximum flood of 600 M3/sec and has been tested in handling the
maximum computed flood of 800 M31sec. The average flood river discharge
is 200-300 m3/sec. Stream velocities on the apron are as high as 11-12 m/sec.
The dam apron has a stepped construction: piers, then a 2-m long spillway
plate with a 1:3 slope, then a 6-m long horizontal platform, then a sloping floor
throwing the water 3-meter deep to the river bed, and finally, triangular-
section dentals. The concrete apron is 0. 8 m thick, and its overflow part is
1. 0 -.-n thick. The project provided for a wooden revetment coating the apron

and dentals, but the revetment never materialized in practice. During floods,
the drifting material consisting of fractions of ZOO mm size and some Individual
units up to 2 m caused considerable wear and destruction to the structure
concrete. Particularly after the disastrous flood of 1952, the concrete apron,
the down apron, and the downstream bed were considerably damaged. Causes
of destruction are analyzed, repair work is described, revetment materials
are recommended, etc. Photographs of the damage are supplied.

TITLES Plastoooncrete on the lase of 114*1 OIFA") Monomer
PERIODICAL: Beton i zhelezobeton, 196o, No. i1, pp. 503-506
TEXTi A plastoconcrete was investigated, in which cement was sub-
stituted by the synthetic "FAII furfurole-acetone reein, which is a conden-
sation product of furfurble with acetone in an alkaline medium. The Per-
ganskiy gidroliznyy zavod (Fergana Hydrolysis Plant) was the first in the
USSR to develop the production of this monomer. The plastoconcrete based
on this monomer was tested at the VNII-plastmaeo (VNII of Plastics) and
MKhT1 im. Mendeleyev. In 'the case of a coarse filler the following formu-
lation was usedc 1 part of filler, 0.09 "FAII monomer, 0.02 furfurole,
0-03 benzenesulfoacid; in the case of sand filler: 1 part of sand,
0.14 "FAII monomer, 0.02 furfurole, 0-04 benzenesulfoacid. The hardening
lasted-from several minutes to several months. The final strength depended
on the amount of acid present and on the temperature of the surrounding air.

The optimum amount of acid is 25 - 30 ~ of the monomer weight. The results
of the strength tests are shown in Table 1.

In order to obtain a 28-day strength already after one day the amount of
acid must be raised. The tests for watertightness showed that samples
25 mm, thick withstood a pressure of 14 atm it the age of 7 days. Testa
carried out at -200C in the course of 50 cycles on 7-day samples did not
reveal changes in the weight and the strength of the samples. The wear re-
sistance is 10 times higher than in cement samples of the composition 1 : 3
at the age of 33 days. Plautoconcrete has a good adhesion to dry cement
samples, but the adhesion to wet samples is low. Sand with carbonate admix-

tures can be used as filler if the amount of catalyst (acid) is increased.
Industrial tests of the plastoconcrete were made at the Verkhne-Chirchik
power station (UzSSR) and at the Pallma dam on the Isfayrom-Say river. The
tests have shown that plastoconoroto.can be propared and laid by methods
used with cement concrete. Tests were also conducted by NIIKhimmash and
ToNIIPodzemehaftstroy. They.have shown that plastoconcrete is resistant to
acids of various concentration, alkalies, solvents, etc It has good di-
electric I)ropertibs-. Wood and other organic material is protected from
rotting when coated with this concrete. Aging tests conducted since 1952
did not show any changes in its quality. It is hoped to reduce the cost of
one m3 of plastoconcrete from 11600 to 600 - 700 rubles by improving the
production methods for furfurole. There are 2 tables and I photograph.

TEXT& The authors describe-properties, production methods, and test
results of organomineral concrete (OMC) based on,"JA" ('IPA") furfural
acetone monomer. OMC is superior to cement conc ,e es as to its physico-
mechanical properties, After 28 days, the maximum compressive strength
is 700 kg/=2~ the tensile strength, 64 - 70 kg/cm2, the bending strength,
2
160 - 200 kg/cm . The concrete is water- and frostproof. The dependence
of the properties of OMC on the type of sand used was studied; beat
characteristics were found for OMC of the following composition (parts by
weight)s Chirchik sand (washed), 1; 'IPA" monomer, 0.14; furfural, 0.02;
benzene sulfonic acid, 0.04- OMC is virtually produced like cement con-

crate. By increasing the content of benzene sulfonic acid, it is possible
to produce OMC on the basis of sands with carbonate impurities. Because
of the high price of "FA'' monomer it is recommended to use OMC for cover
plates, plaster, and the like under conditions where ordinary concretes
are not firm enough. lAbstracter's notes Complete translation-D

TEXT: Plastic concrete made of furfural acetone and andesite sand was
exposed to aggressive media after 80-90 days setting at 200C for 30, 90,
150, or 180 days, respectively. Results: The concrete was stable against
36% Hci, UP to 85% H2SO4, 5% acetic acid, 50% hlkali lye, 25% NH, solution,
26% mgso4 solution, 20% KC1 solution, 40/'* 4H4 Cl solution, kerosene, and
gasoline. It was unstable against 3% HNO 3, 96% H230 41 100% acetic acid,
.benzene, ethanol, and acetone.. Therefore, plastic concrete can be widely
used in the chemical industry; also for boilers in the cellulose and other
industries of hydrolynin; in the manufacture of glucoca from wood waste,
in the processing of lignin, in the production of superphosphate, etc..

TITLE: Natural Convection in an Oil Tank
PERIODICAL: Inzhenemo-fizicheskiy zhurnal, 1959, Nr 9, pp 101-105 (USSR)
ABSTRACT: When petroleum and petroleum products are stored in metallic ground tanks,
convective currents of a liquid and a gas-air mixture may arise due to
temperature differences between the vertical metallic wall and the liquid.
The-author writes down equations of heat transfer for this system and
simplifies them under an assumption that the rate of flow does not change
along the wall of the tank but depends on the value of y-coordinate alone.
The integration of the differential equations, 4 - 6, yields an expression
for the velocity vector along the x-axis W x given by Formula 8, and the
value of heat transfer coefficient Is expressed by Formula 14 which is
,similar to that obtained by Mikheyev jef f, The magnitude of the average
convective liquid flow Is g1ven by Formula 17;

where ej is the coefficient of volume temperature expansion of the liquid,
0 is temperature difference, Cis the thickness of the boundary layer,
and Y., is the physical parameter of the liquid related to the average
temperature of the boundary layer. The theoretical conclusions were com-
