TITLE: A Method for Measuring the Activity of Nuclei Exposed to a
K-Capture (Metod izmereniya aktivnosti yader, ispytyvayushchikh

PERIODICALt Izvestiya Akad. Nauk SSSR, Ser. Fiz., 1957, Vol. 21, Nr 7,
pp. 1020 - 1024 (USSR)
ABSTRACT: The isotop4m with a deficiency of neutrons are to be considered
as the overwhelming portion of the products of the interaction
between nuclei and particles with an energy of several hundred
MeV. In the case of middle and heavy elements such isotopes in
most cases disintegrate by means of the K-capture. The specific
peculiarities of the formation of isotopes at high energies as
well as of the process of K-capture, make great demands on the
method: a) it must guarantee a reliable recording of the weak and
weakly-ionizing radiation (10 - 100 keV), b) the efficiency of
the radiation recording must be sufficiently high and as far as
possible the same for different intial elements, c) beside
X-rays or Oghe (Auger?) electrons the apparatus should also re-
Card 1/3 cord the concurrent radiation of positrons and electrons, as well

A Method for Measuring the Activity of Nuclei Exposed to a K-Capture
as the accompanying r,-radiation, d) the ,?ossibility should
exist to check the connection between the- recording radiation
and the processes of the K-capture in the case of the respective
elements. For their investigations the authors chose X-rays, and
the Geiger counters as recorders. Figure 1 shows and explains
the scheme of such a magnetic analyzer. The calculated effective-
ness curve (I) of the recording of X-rays is given on figure 2,
as well as the curve (II) of the variation of the absorption
correction for different Z. The process of the identification of
X-rays in the case of weak radiation intensities is also explain-
ed. Fi Rut re 3 records the variation of the mass coefficient of
the V X-ray absorption in different elements. All resulting
values are contained in a table and compared with the calculated
ones. This method proved to be suitable for work with a great
number of elements up to and including rare earths. It differs
advantageously from the other methods by the simplicity of the
apparatus an&t the reliability of the identification of radiation.
There are 3 figures, I table and 8 references, 5 of which are

ABSTRACT: In the present paper experiments are described which had
already been carried out in 1951 - 1952, the results
and evaluations of which are, however, published only
now. Bi(Z=83) and Pb(Z=82) was bombarded with protons
of energies of from 180 to 480 MeV, and astatine isotopes
(Z-85) were obtained, the production of which was inves-
tigat1d1by a radiochemical method. With tho exception
of At 1 , which was also obtained from lead, -

of At~' in lead was,,jlo-31cm. The authors endeavored
to explain the phenomena observed by assuming them to be
theresult of a secondary reaction of the capture of
fission pro,lucts (a-particles or Li-nuclei). The production
of light astatine isotopes might be explained by the
capture of high-energy protons with a following emission
of n- -mesons and several neutrons. The cross section
for the production of a-particles with E >20 MeV from
bismuth irradiated with 480 MeV protons is determined
from the astatine yield as amounting to (5 to 6). 10-25cm2.

0.2-2 hours. For determining the yield, different thicknesses of lead
foil were irradiated for 2-10 hours, The dependence of the a6tatine
yield on the proton energy is given in Table 1:

(T 1/2 - 25 min); At 205/At2ll_ 0.1. The yield of At 211 as a function of
the energy of the bombarding particles (agp9d) is shown in Fig. 1. The
highest yield (-10-3 pb) was obtained by bombardment with alpha par.
ticles, and this is only slightly dependent on the energy. When the
alpha energy is high, At 211 may be formed also by the alpha ce.pture of
Pb 206 (and %-n. emission) or Pb 207 (and n- emission). The fraction of
these reactions is, however, unimportant. Fig. 2 shows the At 2,11 yield

as a function of the target thickness. The yield increases monotonically
from 0.03 to 0.3 mm, and remains constant with a further increase in
thickness. In the discussion of the results, the authors compare the E p
dependence of the total production cross section of astatine isotopes
from lead with that of iodine isotopes from tin (Fig. 3). An estimate of
the energy spectra of the Li fragments and their production cross sec-
tion from lead is made by a method suggested by B. V. Kurchatov et al.
(Ref. )0). Ar.,suming that Li 69 U7, and Li a have similar energy spectra,
the spectrum may be deacribed by P(E)dE - T_ 2 (E-V)9xp(.(E-V)/T)dE. The
isotopes by oapture of U 6 and U7 were calculated according to
Jackson's method, and are represented in Fig. 4 (d - f(EU )). The ratio
between the U yields from lead was determined to be
Li6 :L17:Li8.. 0-55:0.41:0.043. The parameters V and T from thq spectrum
formula are given in Table 2 for several yield ratios. The best agreement
with the experiment is found for V - 6 - 10 Me7 and T - 10.5 - 11.5 Mev.

The Brinell method was employed to determine the hardness of piercing
mill 12 XH3A (12KhNZA) steel mandrels after 2, 13, 14 and 82 passes. To deter-
mine the effect of temperature on hardness, the investigated specimens were an-
nealed for 5 hours at 200, 400 and 6000C. Curves were plotted showIng the distri-
bution of hardness on the mandrel surfaces and along their axes. It was estab-
lished that with a greater number of passes the hardness of the mandrels in-
creases; the maximum hardness value corresponds to the pressing section of the
mandrelj with higher annealing -semperatures the hardness on all sections of the
mandrel decreases gradually.

TITLE: Experience Gained from the Use of Plastic Covers
PERIODICAL. Stroitelstvo truboprovodov, 1960, No. 9, pp. 9 - 13
TEXT-. For the protection of underground pipes polyethylene and polyvinyl
chloride plastics have been employed. They must be applied in thick layers to be
effective. The Institute Gipromorneft' has developed in 1958 a cover made from
polyamide tape 4K-4 (PK-4) which has been tested in practice by Azneftezavodstroy
Trust on the main pipeline Karadag - Severnaya GRS in 1959 and by Zakpromstroy
Trust on the gas-distributing network in the city of Sumgait. In both instances
tests were carried out in highly-aggressive soil. Pipelines were provided with
both plastic covers and electro-chemical protection, while arrangements for in-
spection at various points were also made. Results of tests with various kinds
of cement and methods of application are shown in Tables 1 and 2. Poor adhesion
occurred from layers of cement being too thin or In the event of cements being
made with volatile solvents. This causes the formation of blisters and hollow

places under the cover, into which moisture is being drawn, resulting In corrosion
of the metal. In the case of polylsobutylene cement the durability of the tape
suffers under the effect of aromatic hydrocarbons. The strength of the tape
improves upon application of cement made from petrolatum, the reason for the
improvement being a reorientation of the molecules. If using thick layers (up to
1.mm) of gun oil, the cover remains unchanged for a long time. The tape retains
its elasticity and other mechanical properties; there are also no traces of ~or-
rosion on the metal. Photo I and 2 show to what extent cover and pipe metal have
been oreserved after having been kept a year and a half in saline soil. Specific
resistance of the cover, as can be seen from Table 1 after 2 years of service, is
12 '000 to 180,000 ohms. Various kinds of cement on a resin or oil product base,
can be used for at-tach-ing plastl-~s to pipes or fastening tape together. 71,
important that the cement retains its initial properties and does not change its
structure after some time; it also should not contain any solvents (especlaliv io
aromati6 ones) liable to cause swelling up-der the tape. Viscosity of tile cem&n,.
should be sufficient to prevent the tape from detaching Itself from the met&!.

increasing labor efficiency. Combined methods are considered, using bitumen

of plastic tape are applied with 4 cm overlapping. The work in question can be
done on the site or part of it In the workshop. The machine OMA-1 (IML-1 ) used
for mechanized work on the site for making bitumen covers can easily be adapted
to applying petrolatum cement and plastic tape. On leaving the insulating machim
the finished insulated pipeline section Is lowered into the trench. The rules
of Gosstroy USSR so far do not provide for the making of plastic covers, There
are 2 photographs, 3 tables and 7 references. 6 Soviet, I English.
