TITLE The Diffusion Hygrometer.
PERIODICAL Surn. techn. fis, 26, fasc. 4, 887-894 (1956/1
Publ. 4 / 1956 reviewed 9 / 1956
The diffusion hygrometers described here are based upon the fact that in the
chamber of the device containing a dry and a humid substance (and which is
separated from the material to be investigated by a porous wall) under- or
overpressure is produced while the diffusion current is steady. Here 4 vari-
eties of these hygrometers are described each of which may have its own par-
ticular sphere of action. The two chamber hygrometer consists of two chambers
which are separated from the surrounding atmosphere by uniform porous separat-
ing walls (of coal or mipor). Construction and mode of operation of the de-
vice are described. Using the two chamber hygrometer is complicated by the
necessary determination of the apparatus constant K, the necessity of knowing
atmospheric pres3ure, the diffusion coefficient, and air humidity.
The three ch~mbe= hygrometer: In order to make the apparatus constant of the
hygrometer independent of temperature and pressure, PROCHOROV and DERJAGIN
suggested a three chamber hygrometer. The first chamber is dry, the second
and third are used for compensation. Construction and operation of the appa-
ratus are discussed. By means of this hygrometer it is possible to determine
humidity independent of temperature and atmospheric pressure, above all
also in the case of negative temperature. Next, hygrometers with assumed

sensitivity and slight inertia are described. In order to reduce inertia and
4.
at the same time to increase sensitivity, the manometer travels are stren,-,h-
ened by negative back-coupling. The four chamber hygrometer consists of 2
parts: of a two chamber hygrometer with a dry chamber, and of a device con-
taining a dry and a humid matter and a porous wall. Humidity was measured by
determining the ratio (decrease of pressure between dry and humid chamber /
decrease of prGssure measured by the two chamber hygrometer with dry material).
Conclusions:. The above described types of diffusion hygrometers offer some
advantage against devices hitherto in use for measuring air humidity; they
may be constructed so as to have different degrees of sensitivity and inertia.
Diffusion hygrometers have a linear scale and make it possible to measure
humidity within a wide range of temperature, also below 00 C.

ABSTRACT- Not only the number of particles within the volume unit, but
also their dimension distribution can be deterinined by the
ultramicroscopic flow investigation method. For this purpose,
an optical discriminator (photometric wedge), making it possible
to obtain the particle-brightness distribution, was mounted Into
the target illuminating device of an ultramic-roscope, A new
wedge-graduation method is described; the graduation curves of
the dependence of particle dimensions on the wedge position can
be obtained quickly, when applying the method mentioned, The
authors report on the flow method applied to the 5tudy of the

moistening chamber and a cooling channel, in which vapor condensation on
the condensation nuclei proceeds. The condensation nuclei, enlarged in
this way, are carried away by the air current, arrive at the cell of ths
ultramicroscope, and can be recorded by the observer. The op-,,Imum opera-

TITLE: A Diffusion Chamber with Supersaturation Which is
Constant Both in Space and Time
PERIODICAL: Pribory i tekhnika eksperimenta, 1960, No 2,
ppA5 -- 47 (USSR)
ABSTRACT: The supersaturation in a Wilson chamber disappears
rather rapidly owing to the unavoidable condensation
of vapour on the walls and also due to heat transfers
In diffusion chambers supersaturation is constant in
time, but not in space. The method suggested in the
present paper is free from these two disadvantages
and can be used to obtain supersaturation which is
constant both in time and in space. The idea is to
use a periodic variation of the temperature of the
walls of the chamber. The problem is formulated as
follows. It is assumed that the walls are always moist
and the flow of liquid down the walls can be neglected.
Under these conditions the thickness of the layer of
Cardl/5 moisture is constant. If one neglects the heat transfer

82880
S/12o/60/000/02-/011/052
A Diffusion Chamber with SupersaturafolgWRI"Ch is Constant Both
in Space and Time
associated with diffusion then the periodic change in
the temperature of'the walls will produce a heat wave
propagated into the chamber. If the temperature of the
walls is known then one can calculate the density of the
vapour as a function of time. If the period of the
-temperature oscillations on the walls of the chamber is
taken to be sufficiently short, then the temperature and
diffusion waves are damped out in the neighbourhood of
the walls and most of the volume of the chamber is
maintained at an average temperature and density which
can be expressed in terms of the temperature variation
6n the wal]S. If the amplitude of the temperature
oscillations on the walls is small, the mean density
of vapour in the chamber will be equal to the saturation
vapour density at the average temperature of the walls
and, consequently, the supersaturation will be equal to
unity. At larger amplitudes of the temperature oscil-
Card2/5 lations, the supersaturation will be greater than unity.

S/12o/6o/oOO/02/011/052
E212~EJA4
A Diffusion Chamber with Supersatura o ich is Constant Both
in Space and Time
The supersaturation will increase with the amplitude
of the oscillations in the temperature of the walls,
A chamber based on these ideas is shown in Figure 2.
The working walls I were made of aluminium foil 0.05 mm
in thickness and were in the form of squares 200 x 200 mm.
These walls were attached to the perspex frame 2 which
was 50 nun thick. The heat waves are practically damped
out at a distance of 3 mm from the wall when the period
of 1 see is used. The side walls formed by the frame are
kept atthe average temperature of the chamber. This
tends to reduce side effects but does not eliminate them
altogether, so that thewaidrig volume is smaller than the
geometrical volume. The heat was applied by passing
short but large current pulses (of the order of a few
hundred amperes) through leads in thermal contact with
the aluminium walls. The heat was removed by copper
vessels 6 (Figure 2) filled with a mixture of acetone
or alcohol and solid carbon dioxide. The thermal
Card3/5 contact between the refrigerator and the aluminium wall

of the chamber was through a thin paper layer 7 The
rate of cooling could be adjusted by varying the thickness
of this paper. This construction was used to obtain a
temperature change of + 3 0C with a period of 1 see at an
average temperature of-20 0C. The chamber was heated for
0.2 see and cooled for 0.8 sec. The supersaturation
in the chamber calculated from these data should be about
1%. In order to increase the degree of supersaturation,
a larger amplitude in the temperature oscillations is
required. The chamber can be used to reproduce slow

TEXT: The experimental set-up for measuring diffusive
long-range forces between water drops and a I mm-diameter silvcred
globule iG described together with some-results of the research.
The measurements were ciade with a torsion balance. 'This had a sen-
sitivity of 0.4-10-9 g and was fitted with an autocollimation raster
photorelay, an amplifier, and an electronic recording potentiometer. i,i
The droplet and the globule were grounded dui~ing the measurements
in order to obviate the possibility of the induction of the electro-
static charges. The diffusive forces were determined (after elimin-

ating the inf luence of convection currents) at a dif f erincr hu midity
of the surrounding medium and at different distances. Ho diffusivil
forces were detected when the surrounding medium was fully saturated
i-dth water vapor. If the htmidity is nil, considerable diffusive
forces appear, and their magnitude depends on the distance. At 4r/0
humidity the diffusive forces are considerable, but their abatemint
is more marked than is the case with zero humidity. In this event
the dif--"'usive forces are inversely proportional to the square of
the distance in the raiige from 5 to 12 nim. In t4is interval the
order of magnitude of the repulsive forces amounts to 1,10-9 9.. On
-L'n-- further.approach of the drops the square relation is disturbed,
and the forces grow more slowly. The experimental data cited agrees
well with the theory, developed by B.V. De agin and S.S. Dukhin.

Hence, the dependence of, D on 1.1i may be linear (K - 0) or square (K>~>w).*
The diffusion of Sr 90 through wet quartz sand (I), wet black soil (II),
wet soddy medium-podzolized soil (III) and wet loamy chestnut soil (IV)
was conducted to prove the correctness of the above assdmptions.
Sr90C12 was caused to diffuse through columns filled with these soils durirg
15 months. Humidity and radioactivity of the individual column sections
were measured. Results: In a-reement with Eq. (11~, log c was a linear

If the humidity is expressed in parts by volume, 9 - doW, then D versus 9
is linear for I and square for III whereas the curves 4or III and IV showed
inflections caused by a complex function s(G). K is 0.011 + 0.005 for I
and 12.0 + 1.0 for II. For III and IV, K was estimated to ~e-6 and 8,

TITLE: on the diffusion of strOntium-90 it' soil and sand
PERIODICAL: Radioldlill'iya, v.4, no.2,1962, 205-211
TEXT: The author attempted to derive an expre3sion
describing simultaneously diffusion and adsorption processes for
Sr90 taking place in soil. The following expression was
obtained for the coefficient of diffusion D for a case where
a linear adsorption isotherm applies:
D d,V2Do (10)
W + k
where Do = diffusion coefficiont of a substance in the liquid
phase, k = distribution coefficient, w = relative content of
moisture in the soil. Experiments were carried out to confirm
Eq.(10), whereby the dependence of diffusion of Sr90 on moisture
was investigated in two media with different adsorptional
properties: 1) quartz sand; 2) black earth. it was found that
Eq.(10) applies to the sand and black earth. In the latter case

depended strongly on its moisture content. This wits found to

;ABSTRACT: Under the influence of an electric field the transport of cations ad-
i - . -o
isorbed onsoil particles takes place due to electromigration and electr osmosis.
lAn equation is derived which describes both of these procesves. Knowing the val-aes~
!of the diffusion coefficient D and the-velocity of ions V one can calculate the ex-;
itent to which the soil can be purified, at some point X, to a prescribed degree.
i
iIn principle the possibility of purification of the soil from radioactive contami-
i
!nation is detezmkined by the mobility of.the contaminants in the electric field and
',the consumption of energy. The present experiments were conducted to determine the,
an
~feasibility of purification of the soil from radioactive strontium by means of
electric field. In electromigration of Sr" in a soil filled cell the maximum

lactivity peak m:)ves toward the cathode with some decrease of the peak height due to
spreading of the zone. It was thus shown that soil may be decontam-
inated from Sr by this method,.although the process is rather slow. With 100 v
output the consumption of energy for moving the: SrB9 peak was 400-100 kw-hr/m3.
After, 1080 hrs in a cell containing equally distributed Sr89 the fraction of the
original specific activity in.60% of the soil between the*anode and the cathode did
not exceed 1-2'10. The activity between tba'anode and 90% of the distance toward the
cathode was 14% of the original activity in the whole cell. The authors express

iABSTRACT: The purpose of this investigation was to measure directly the effect of
the composition of the soil solution on the rate of diffusion of radioactive iso-
itopes in the soil. The experiments were conducted with Sr-90 without a carrier.
,jThe soil (37 m?/g, specific surface) was wetted with concentrations of CaC12 sOlu-
itions ranging, from 3.3 10-2 to 8-.5 g--equiv/1. The soil was moistened to the extent

TITLE. Determination of the resolving time of a counter
PERIODICAL: lzmex-itellnaya tekhnikat 1961, No.91 pp,, 42-43
TEXT~ The usual method whereby the dead-time of a counter
may be measured is the so-called paired sources method. However,
this method involves the insertion of two radioactive specimens
into the lead castle, which the present author states is sometimes
difficult to do~ The method described in the present note avoids
this difficulty. The method is described as follows. A metal
filter of a given thickness transmits a constant fraction of the
radiation emitted by a given source, whatever the activity of the
source, i.e. I
