Abst: In January 1957, the Second All-Union Conference on Photosynthesis
took place, organized by the institute of Plant Physiology of the Academy
of Sciences, USSR, and by the Facultys of Soil-Biology of the Moskva
University. About 700 representatives of 130 scientific-research
institutes, vuzes and ministeries were present. The introductory report
was made by Aoademician A. L. Kursanov who described the development of
photosynthesis during the last ten years and invited the teienti-sts to
concentrate their work on the application of radioactive and steble
isotopes. Nearly 100 reports were read: 13 on photochemistry, 9 on the
iuvestigation of chloroplAst structure, 19 on the investigation of pigments,
9 on the photosynthesis of imter plants, bacteria, et@!.

TITLE: The Effects of IA-Irradiation on the Properties of Silicon

pp. 275
ABSTRACT: Silicon rubbers are subject to a number of changes in con-
sequence of /r-irradiation; these changes are caused by the
"radiation sewing". Young's modulus increases linearly with
the dosage of irradiation; this is the case up to dosages
originating from 150 - 200 mg of Rg-equivalent. The vitri-,
fication temperature (-120 to -125 C) practically does not
change in irradiations ug to 100 mg of Ra-equivalent and in-
creases to (-100 to -115 C) when the irradiation is carried
out by a 270 mg Ra-equivalent. In the case of "radiation
sewing" the velocity of crystaPization decreases. The melt-
ing0temperature drops from -35 C at the starting point to
-55 C when the rubber was irradiated by a 40 mg Ra-equivalent.
An irradiation with a 100 mig Ra-equivalent suppresses crystal-
Card 1/2 lization almost completely. By this a hard rubber is obtainedg

TITLEt On Isotopic Exchange between Gaseous Hydrogen and Solid Poly-
mere Under the Action of Nuclear Radiation (Ob izotopnom obmene
mezhdu gazoobraznym vodorodom i tverdymi polimerami pri dey-
stvii yadernykt izlucheniy)
PERIODICALt Doklady AN SSSR, 1958, Vol. 118, Nr 29 PP. 315-316 (USSF)
ABSTRACTt In the case of irradiation of polymeric hydrocarbons gaseous
products, which mainly conatain hydrogen, are separated out. The
explanation of the problem of the reversibility of the correspon-
ding process, i.e. of the possibility of the penetration of hy-
drogen from the gaseous phase into the molecules of the polymer
during the irradiation would be desirable. The authord@ried to
explain this problem by the method of the marked atoms, using
deuterium; they studied the exchange of isotopes between the
gaseous deuterium and various solid polymersp.-a the radiation
field of a nuclear rector. The following polymers of the vinyl-
aeries were examined: Polyethylene, polypropylene, polystyrol,
dard 1/3 divinyl-caoutchoue, polymethyl-metacrylate. The performance of

the measurements is described shortly. A table illustrates the
effectively found percentage of deuterium in@he above given poly-
merics after the irradiation. The results of various parallel
measurements differ at the most for o,o2 per cent. On occasion
of all these polymers it was shown in particular that the pene-
tration of deuterium is not connected with the adsorption of
gaseous deuterium. The control tests, which were made for thiz
purpose, showed that, if there is no radiation, no dueterium was
found in the polymer. The effects, observed here, obviously are
cuased by a chemical interaction between the molecules of the
polymer and the molecules of the d6ut-erium on occasion of the
action of deuterium. The highest quantity of deuterium penetrated
into polyethylene and into polypropylene. In polybutadiene and
polystyrol the exchange is some what slower, whereas in the case
of polymethyl-metacrylate no signs were noticed of an exchange.
At present a mechAnism with the formaii049f free radicals, i@s
assumed for polyethylene: H-CH9-Rl-- 4 H-CH-R, + H.Probably the
deuterium penetrates in the case examined here because of a
reaction between a.polymeric radical and a deuterium molecule
Card 2/3 into the polymer: R + D2---->RD + D, RH + D 4 + HD. The equili-

radicals. There are 1 table, and 5 references, 4 of whi0h are

with a C--factor near 2.0036 was observed in all samples. After
"thawing" of the sample dovin to room temperature the signal
was in all cases found to change. In some cases, the signal
vanished completely as a result of "thaviing" (polyisobutylene,
polydimethyl siloxane, natural rubber). In the case of other
materials the character ff the signal and its fine structure
changed considerably. A comparison of all data obtained gave
the following result: The character of the spectra obtained
by investigating not "thawed" samples can be fully explained
by the assumption that the predominant primary chemical act
in irradiation is the strippin,-, of one of the C-11 bonds in
the mnin chain (or in the absence of a i.;Iain chain the strip-
ping of a C-H bond in a lateral chain). The specti-Lim of

ABSTRACT: By the action of an ionizing radiation the mechanical
properties of polymers may be changed to a considerable
extent. The authors of the present paper investigated some
mechanical properties of polymers during irradiation. The
investigation was carried out in water-cooled vertical
channels. The fluxes of the neutrons and r-quanta, as well
as the energy dose absorbed by the samples were measured on
this occasion. Moreover, several simple devices for
measuring the mechanical characteristics of polymers under
irradiation were constructeu, and, especially, a device for
recording the extension curves (6--F-) for use in a reactor
were reconstructed. The authors investigated polymers of
different radiation resistance and different character of the
Card 1/4 most important radio-chemical variations. By comparing the

Polymers
mechanical properties of the samples located in the radiation
field with the properties of original samples (and with
samples which, though irradiated, were tested after
irradiation) reversible radiation-mechanical effects were
discovered. They are based upon a temporary reversible variation
of the mechanical properties of the polymers. This variation
occurs during irradiation and vanishes as soon as irradiation
ceases. The authors observed the following reversible
processes: 1 ) Decrease of the strength of polymethylmetacrylate.
2) Decrease of the limit of the enforced elasticity ffB Of
polyvinyl chloride. 3) Increase of breaking elongations of
polyvinylchloride. 4) Increase of rdaxation rate of the tensions
in the investigated substances. 5) Increase of the creep rate
of polyvinylehloride, polystyrene, teflon, and rubber. Points
2-5 are then discussed in detail; thus it was found thatiT B
decreases in the case of a dose rate of 46000 rad/sec by -25 %
and increases approximately linearly with an increase of the
dose rate. After irradiation ceases, the reversible effect

remains. A table contains the values of creep rate under
various conditions. As a result of the irreversible
destruction effect, the creep rate increases. Also this effect
increases linearly with increasing dose rate.Ttae diagrams 3-4
show the considerable reversible change of creep rate caused
by the switching-on and -off of irradiation. The reversible
radiation-mechanical effects may be of physical and also of
chemical nature. The molecules excited by the ionizing
particles during the dissipation of energy "pass through"
states with weak excitations, which do not suffice for the
stripping-off of the chemical bonds, but which correspond
to local heating to high temperatures of short duration. This
may accelerate the relaxation processes and change several
properties of the substance. However, &lso a chemical
mechansim.must be taken into account. To what extent it is
able to explain the reversible radiation-mechanical effects
can be explained only after further investigations. There are
4 figures, 1 table, and 2 Soviet references.

ABSTRACT: The present paper is intended to work out the construction of a
device for the simultaneous measurement of the luminescence
and dark6ning of transparent materials in a nuclear reactor
and to deal with the carrying out of experiments by means of
this apparatus. The usefulness of parallel measurements of
the yield of the luminescence and of the darkening of the
sample may be seen from the close connection between these
phenomena during irradiation. The device consists of an
aluminum tube of 5 m length and 60 mm diameter, inside of
which two tubes of the darkening tract (polished inside) and
one polished tube of the luminescence tract were fitted.

of 65 mm (with external water--cooling) of the experimental
reactor VVR. In this reactor ordinary water is used as
moderator and coolant, The Ghannel was near the active zone
of the reactor. By variation of the power of the reactor
various valueo are obtained for the differential dose. In the
case of all experiments temperature remained below 350. The
samples consisted of '10 mm thick disks with a diameter of
20 mm. The following quantities were measured by remote control:
a) the brightness of luminescence and its time dependence at
various differential doses, b) The darkening of the samples
and their time dependence at various differential doses.
c) measurement of darkening after irradiation was stopped.
Measurements were carried out on various types of quartz,
pyrex glass, cerium glass, polymethylmethacrylate, and
polystyrene. In the case of all quartz samples, the relation

on the dose. The autao-@,s found that the crystallization properties of ir-
radiated polyethyl.nc strongly depend on its phase condition during irra-
diation. Irradiaticn in a molten state led to a fast drop of T and a de-
crease of the cry:jtallization degree. On irradiation in a crysTalline
state, the authors first observed a slight drop of T , then a constant
value, and then a slight increase. The crystallizatimon degree decreased
more slowly than on irradiation of melts. These effects are interpreted
as different types of network in the amorphous and crystalline states.
In the amorphous state, the network fixes the disordered state of chains.
In crystalline samples, however, the cross links fix the local order of
polymer chains. This effect corresponds to the effect of increasq of T M
in rubbers when their chains are oriented. There are 4 figures, 1 table,

PERIODICAL: Atomnaya energiya, 1960, Vol. 9, No. 4o PP. 321 - 323
TEXTY,-- A steady calorimetric method is used for measuring the
radiation energy received by a sample if the dose rate is not too high and
the effect of other energy-generating processes in the sample is
negligible. For intense irradiation (high dose rate), this method is not
applicable, particularly because the establishment of thermal equilibrium
takes too long a time; in this case, the sample is so strongly heated that
it either melts or disintegrates; at least the high absorbed integral dose
changes the structure and properties of the sample significantly, For this
reason, the authors of the present "Letter to the Editor" developed in
1957 a simple nonsteady calorimetric method which is suitable for studies
on reactors and other sources of strong radiation. The method has been
testod during the last few years. The principle of the method is as
follows. A sample for dose-measuring is placed at time t-O in a radiation

conditions that the temperature at the center of the sample increases
linearly for a time i independently of the surrounding temperature,, i is
proportional to the square of the characteristic sample dimension d and
inversely proport-ional to the coefficient of thermal diffusivity Z. There-
fore, dT/dt is a function of the dose rate and heat capacity of the
sample, and the dOBe rate can be calculated from the formula

diameter and 50 mm height). This size has a T value of 2 - 3 minutes which
is required for the meqsurement of dT/dt (Fig,, 1). In this time interval,
the mutual shielding of the parts of the sample may be neglected. Copper-
constantan thermocouples were used for the measurement of temperature,. The
construction of the dosimeter is very simple (Fig. 2),, All parts with the
exception of the thermocouple consist of nonactivizable materials. The

TEXT: The present study, which is a continuation of earlier work
(Vysokoriolekulyarnyye soyedineniya, 2, 1512 (1960)), was cay'ried
out to determine the effect of lattices formed when amorphous or
crystalline polyethylene (FE) is irradiate'd, on the physical and
mechanical properties of the polymer after irradiation. Low- and
high-pressure PE specimens were irradiated (u-p to 1625 Mrad), under
He) in both.amorphous (130 - 1600C) and crystalline (45 - 500C)
btates. Crystalline s-pecimens were then heated to 1500C and slowly
cooled. Amorphous ?B gave rise to la-latticesl@ whilst both a- and
'k-lattices' formed in crystalline irradiated samples. The modulus

still rigid and crystalline (E--4800 . The m.p. of a-PE decreased

whilst the corresponding effect for k-PB was less pronounced and
discontinuous. The degree of crystallinity was simultaneously low-

ABSTRACT.- There am as yet no reliable data on the binding energy of the
complementary chains in the double 1zlix of DNA. This is due chiefly to the
experimental difficulty of direct microcalorimetric determination. The authors
worked out a method of determining the binding energy by introducing Into BNA
a small number of local intermolecular or covalent supplementary bonds (or clips)
between the complementary eliains. When a dye (actinomycin or acridine orange) acts
on DHA, the melting curve of DFA changes characteristically. The melting point and.
the melting-temperature range increase. If all dye molecules introduced into the
solution are bound to DUA so that each clip is formed by one dye molecule,, the clip
c3neentration is determined by the formula a 2D/Pj where D-is the molar concen-

must not go into solution but stay bound to the DNA molecules. This @.,ondition is
essential only till melting reaches 60-70%, and it was found that actinoiVcin,
proflavins, and acrIdine orange meet it at low ionic strength of the solution.
Results show that the heat of the helix-coil transition in DNA depends markedly
on the ionic strength of the solution. At a melting point of 55G, this heat of
transition is 2.7 + 0.7 kcal/mole. Orig. art. has: 1 figure, 1 table, mid 2

by volume was also investigated. The B-2 channel of the BR-5 reactor
served as the neutron source. The measurements were made under con-
ditions of semi-infinite geometry,'and the neutrons with E > 3 MeV
leaving the channel had the same energy distribution as the fission
spectrum, becoming softer at low energies. Sulfur and aluminum
threshold indicators, thorium fission chambers, and proportional
recoil-proton counters were used as fast-neutron detectors. Thermal
and epithermal neutrons were detected with copper and indium reso-
nant indicators. To permit comparison with the available results,
the experimental data were converted into neutron attenuation func-
tions of an infinite flat isotropic source. The experimental data
show that the neutron relaxation length in iron increases for low
energies, while in carbon it remains practically constant over a
wide range of energies. Consequently the addition of iron to the
carbon decreases the relaxation length of the neutrons in the upper
groups (E > 2 MeV)'# while the addition of carbon to iron decreases
the-relaxation length of the neutrons in the 1--1.5 McV. By choosing:

the suitable composition of the mixture it is possible to make the
neutron relaxation lengths practically equal over a wide energy
interval. The use of such a mixture, which is relatively cheap and
heat resistant, is quite promising. "The authors are grateful to

perimental results and to A. A. Goncharenko for help with the worlc."
