the distribution coefficient of Sr is linearly dependent on the logarithm
of the molar ratio of the total quantity of the analogue to the sorbent.
The given equation is said to be derived from the law of active masses. The
authors further show that barium is stronger than calcium in suppressing the
sorption of SOO with active manganese dioxide; this fact leads to the con-
clusion that the formed sorbing compounds of the calcium and barium manganate

more subjected to hydrolysis then -the other. The relationship described
above was derived from the following oonsiderationst 1) the sorbent is lo-
cated in the range of saturation b the analogue (barium or calcium), 2) the
pH of the aolution is cpstant, 3~ the ratio of the activity coefficients
of the analogues and Sr in the solid phase is conotantp which is the same
as the absence of a noticeable interaction between the adsorbed cations (Ref

equality of the ion charges of these analogues and Sr go during the exchange

TITLEs Contribution to the theory of the distribution of
micro-quantities of radioactive strontium between
hydrated oxides and the solution
PERIODICALi Radiokhimiya, v-3. no.6, 1961, 654-661
TEXT: In spite of the considerable scientific and technical
importance of the processes of radioisotope adsorption on metal
hydroxide, the mechanism of the process is still far from being
elucidated, especially at micro-concentrations of radioisotopes,
and no unified ideas have so far been formulated for the
co-precipitation of radioisotopes with the hydrates. These
problems are analysed theoretically and a series of equations is
derived for the absorption of-micro-quantities of the cations of
radioisotopes (which do not form radiocolloids) by the precipitates
of metal hydroxides capable of behaving as cationites in acid media.
The following assumptions were made in the derivation of the
equations: 1) the hydrated oxides have ion-exchange properties
and, under certain definite conditions, behave as a cationite in

acid mediumi 2) the law of active mass is applicable to the
systemi and 3) the radioactive isotope behaves as an electrolyte
at infinite dilution. The equations were checked by plotting
experimental data obtained for the absorption of radioactive
strontium (Sr90) by ferric hydroxide and active Mn02 an a function
of the p11 of the medium. The S-shaped curves obtained represent a
general function of the type y = C + mpH and thereby confirm the
correctness of the assumptions made, especially with regard to the
ion-exchange character of the sorption of strontium by metallic
hydroxides. I.Ye. Starik, A.I. Novikov, L.G. Kuz'mina and
Yu.V. Morachevskly are mentioned in the article in connection with

125-fold amplification has 0,001-0.002 mm scale divisions and produces inadequate'
line shadow on the screen because the illuminance of the latter is too weak
(0.5-2 lx). The new system has an improved photoelectric transducer with 3-ight'

of a dark line in the field of view of the photocell causes a pulse signal on
the amplifier output. The diagram is oscillated by an electromagnet connected to!

the corresponding cases by the'author earlier (Xzvestiya LETI,. No.
47, 1962). Allowance is made for the concentration of the field in
the ferrite, which plays the decisive role in the theory of opera-
tion of efficient phase shifters. Simple formulas are proposed for
the ferrite-slab calculations so as to ensure.maximum utilization
of this effect. The calculations are confirmed by experiment. -The
good agreement between the calculations and the experiment for the
case of a single slab leads to the conclusion that'the proposed cal-
culation procedure is valid also for other ferrite structures with
analogous physical phenomena. -This applies also to-the phase
shifter of Reggia and Spencer (Proc. of'IRE, v. 45, 11, 1957).

considered. A~,system of two transverse electrccegnatic vaves is
introduced, equivalent to the system of electric wA magnetic vaves. For each of
these types, a characteristic equation is obtained in the case of two layers of a
dielectric in the waveguide. Plots are made for the dependence of the
propgation constant in a partially filled-wavegulde as a function of the
couposition and thickness of the filling dielectric, 0. Postnoy
