ABSTRACrt Methods are described for individual dosimetry. The irradiation
doses of the personnel aboard the "Lenin" icebreaker received after three years
of service at the nuclear reactor are given. The average dose was 1*62 biologi-
cal rad. equivalent per year, which is more than three times less than permiss-
ible. It has been found that the contribution of thermal neutrons to the total
dose was small (average value 8%; maximum 18%). The irradiation by Beta particles
and fast neutrons is negligibly small. The general health of the nuclear personnel
was comparable with that of the rest.of the crew. Orig. art. hass 1 figure,,

ABSTRACT: This is a summary of an article by Pszona, Ad
ams ka,__
and K. ZiLrnowieck, entitled "Whole body counter for internal don-~
tamination~control" (Warsaw., ]Lngtilutq_ot_Nqg~_qpT.Research, report
no. 4674[IX, 1963). It describes the development, calibration, and
first uti:,lization of a radiation spectrometer for human use, used
for monitoring the internal dose absorbed by personnel exposed to
nuclear radiations. The spectrometer consists of a steel and lead...
shielding chamber, two scintillation counters, and a pulse-height

ABSTRACT; The article describes the GEG-IA gas-are welding torch with vort"
are stabilization, developed and produced at the Kuyby*shevskiy aviatsionny*y
institut (Kuyby*shev Aviation Institute). The anode is in the form of a copper
nozzle with an output diameter of 3.5 mm anci a sliding seating arrangement in
a 4in housing. The cathode used is a tungsten rod 7 mm in diameter set in a fix-
ed p*osition with respect to the nozzle. The electrode assembly is cooled by water
fed'into the tin electrode holder. The nozzle and electrode assemblies are in-
sulated from each other by a textolite casing with screwed-in nipple for argon
feed-. The argon is fed into the chamber through two tangential apertures. The
introduction into the torch of vortical argon feed eliminated nozzle wear. All
three major torch assemblies (nozzle unit, housing electrode unit) are threaded

together and seated with layers of conventional technical rubber. Electric cur-
rent is supplied from a single PS-500 welding emverter. A particular feature of
the argon supply system is the presence in it of a jet 1.19 mm in diameter; dur-
ing operation of the torch, a supercritical pressure gradient is set up on this
jet, providing for constant argon consumption for the established pressure and
var!able torch operation modes. The technical specifications of this torch are
listed. Orig. art. has: 2-figures.

ABSTRACT: The initial part of a turbulent subsonic high temperature stream in a
flooded space is investigated. The velocity and enthalpy profiles at the nozzle
section are assumed to be constant. It is assumed that the formation of the
boundary layer starts at the rim of the nozzle and both the inner and outer boundar-
ies of the mixing zone are rectilinear. Radiation and magnetohydrodynamic effects
are not considered. In these suppositions, velocity distribution, density rho,
and enthalpy J in the mixing zone, and also the position of its inner and outer
boundaries have been found in theory for cases of plane-parallel and axisymmetric
streams. The entire temperature range is divided in-to two sectors, in each of

alpha and beta is used. Diagrams of a gas electric burner and the results of
experimental research of an argon jet at. 9500K are presented. It is shown that
these results agree well with the theoretical ones up to 8000K The bibliography

TITLE: Analysis of Gases and Vapours based on the Negative
Optico-acoustic Effect. (Analiz gazov i parov,
oanovanny na otritsatellnom optiko-akustichoskom
yavlenii.T
PERIODICAL: Optika i Spektroskopiya, 1957, Vol.I1, Nr.6,
pp. 823-825. (USSR)
ABSTRACT: Action of the usual optico-acoustic gas analysers is
based on the fact that radiation of the source after
passing through the gas studied and then modulated at
a certain frequency causes pressure pulsations in the
optico-acoustic receiver due to periodic heating of the
gas in the receiver. It is possible, howevero to use
the negative optico-acoustic effect (Ref.1), i.e.
instead of a source of heat it is possible to use a
refrigerator which is a body with a temperature much
lower than the temperature of the gas in the receiver.
The authors verified the possibility of use of this
Card 1/3 negative effect by filling an optico-acoustic receiver
