ABSTRACT: An extracting method. for the production of pure Y go f-rCM
solutions containing strontium has been worked cut. Yttrium-
8-oxyquinolate is extracted with chloroform. The extraction
done once of yttrium-8-3xyquinolate with chloroform from
acetate solutions and ct-her buffer solutions depending on the
PH value of the solution, the yttrium. concentration in -the
solution and the concentration of 8-cxyquinoline were in-
vestigated. Acetate buffer solutions are more suitable for
extracting yttrium than citrate buffer-solutions. The ex-
traction is complete at PH 7-9. The method of separating
yttrium in radio-chemically pure condition is based on the
extraction of its inner complex by 8-oxyquinoline at a PH
Card value at which strontium does not form a complex with 8-cxy-

without carrier of yttrium is confirmed. The formation of
inner complex Y-salts with benzoyl acetone and thc-ir extrac-
tion with carbon tetrachloride, benzene and chloroform was in-

Figure 1 gives the experimentally obtained data for logq,

corresponds to the formula Y(C 6H5COCHCOCH 3)3* According to
the method of D. Dyrssen and Sillen (Ref 3) the stability con-
ct-n-ts of the yttriun-benzoyl acetonate were detuer.,~.ined (Table 2).
On the baoio of these data a method could be devised to sepa-
rate the radioactive Y90 without carrier. As can be seen from

TEXT: This is a survey on nuclear reactions yielding radioactive isotopes
without a carrier substance, and on methods of separating these isotopes
from the targets. It is shown that, by irradiation in a nuclear reactor,
radioactive isotopes of 64 elements to be used as tracers can be obtained
and separated without a carrier substance. The advantages and restrictions
of the mostpromising methods of separating and purifying radioactive
isotopes without a carrier substance, namely extraction and chromatography
and also of less frequently applied methods (distillation and sublimation,
electrolysis, adsorption in the form of ions anl/or ra"iocolloii,.t~,
procipitation and leaching out) are described. There are 10 refererices-

ABSTRACT: C(?" was obtained from the reaction C&16 (d,p). As a result of the Investiga-
tions conducted it Is shown that the half-life of CcP7 is about three hour
CP71 4. The half-life of 50
min previously ascribed erroneously to s parently, that of Inu"'. obtained from the
reaction CdL16 (d, 2n). The beta-spectrum of C~Lff(3 hr) was Investigated on a beta-spea-
trometer with a magnetic lens. The upper boundaries of the partial beta-spectra have the
energy of 670; 1290; 1800; and 2200 kev. The value of log ft proved to be equal to 4.9; 6.7;
6.9; and 7.6, respectively. The results presented, aA well as the investigations of the
0 Y- coincidence s made It possible to construct a decay scheme of Cdw which differs substan-
v.
tially from that in the literature. Authors express their gratitude to Yu. A. Vorc~~?

ABSTRACT: The ao'rpti*on of cadmium from aqueous ethanol-solutions was. IV;'
studied for the cation, exchange resin KU-2 in the hydrogen, ammonium,
and 8-hydroxyquinoline forms. Cadmium containing the radioactive. isotope
.Cd1l5m, free of the radioactive isotopes W115 and Inll5m,,was used.
The greatest sorption was observed in the case of the ammonium form of the,.
ion exchange resin, at any ethanol content in solution, and the least for
the hydroxyquinoline form, except in the absence of ethanol, in which the
least sorption was observed for the hydrogen form. The greatest sorption
was observed from solutions with the smallest (10%) content of one of the
two components (water or ethanol). The capacity or the cation exchange
resin with respect to cadmium from aqueous solutions was 3.30-3.20 milli-
gram equivalents per gram of-KU-2-for the-ammonium and hydrogen forms.

U~CT: A method is proposed for recovering Na22 without using a carrier.
.Irradiated magne3iwa was dissolved in almost a stoichiometric amount of sul-
furic acid. The solution was evaporated until a film began to form and an
equal or somewhat larger volume of ethanol was added. The solution was
carefully stirred and the liquid with the crystalline precipitate of magnesium
sulfate was decanted onto a glass filter. For more complete isolation of NaV..
the precipitate was washed five to six times with small portions of ethanol.
The extent of Na22 recovery was 95~-97%- Separation of sodium from small
amounts of magnesium passing into the water-ethanol solution was achieved by
ion-exchange on the KU-2 cation exchange resin directly from the.water-alcohol

filtrate. An 0.1 N HCl solution was used in eluting the Na22. In the present,
report, the authors examine the possibility of using organic solvents other
than ethanol, e.g. acetone and dioxane. It was shown that the nature of the
organic solvent added to precipitate nign'osium, sulfate does not affect the
COMP03ition of the crystal hydrate formed. The solubility of magnesium sul-
fate in ethanol, acetone, and diocane, and in their mixtures with water at
201C was determined. The desorption of Na.22 from the surface of crystalline
magnesium sulfate by these solvents was studied. It was established that
solutions of acetone and dioxane containing 10 - 20,19 water exceed ethanol in
desorptive capacity and are preferred for recovering radioactive Na22 from a
magnesium target.,' Orig. art. has: 3 tables. D-PlIS: 35,72A7

-ABSTRACT: The breakdown of 50 to 500 g gaps between 2 mm diameter stainless steel
electrodes in transformer oil,' doubly distilled water, and 'Itechnicalif water(conduc-
tivity approximately 5 X 10-6 mho/cm) was investigated wit Ih up to 500 kV pulses with
nanosec rise time and 30 nanosec duration. The gap was made part of the central
qonductor of a coaxial line and the breakdown was observed with an oscilloscope. The
electrodes were cleaned and examined after every 3-5 pulses, and the maximum error in
measuring the gap was 10 % for the 50 Ii gap and 2 % for the 500 g gap. The results
are presented as curves of mean breakdown time versus pulse voltage; breakdowns that
occurred during the rise of the pulse were excluded from the average. The shape of
these curves is briefly discussed and it is concluded that the discharge mechanism
is electronic in nature. The technical water was found to have as high a dielectric
strength in the nanosecond range as transformer oil. Water can therefore be employed

ABSTRACT: The variation of the isotopic ratio of the isotopes Hg-198 to
Hg-204 was determined in the most different evaporation para-
meters (e.g.tfrom 70 to 2700 C) by means of the mass spectrometers
MC-2 and MC-4. It was determined that a low evaporation velocity
exercises a special influence on the evaporation kinetics.
The relative vapor pressure difference between the isotopes
Hg-198 and Hg-204 can be given from the results:

ABSTRACT: In a capillary the dependence in the isotopic composition of liquid
Hg on the time needed for the passage of a constant current at 41 _+
+ 20C and -10 + 30C is investigated. The time of current passage va-
7ied from a minimum of 34o h to a maximum of 18oo h.
Further , the concentration of isotopes along the electric field
and the dependence of isotope composition at the cathode upon the
amounts of the applied voltage were investigated.
