PReLIKInaRY INFORMATION ON STUDIES OF RADIOACTIVE RAIN.

RevistaMexicanadeFisica 5, 153-66 (1956)

Data on radioactive rain, which were obtained by the
gummed leaf nethod and by collection in a free surface

of water are presented.

The experimental methous are

described.
Some conclusions are obtained on the relative efficiency of the two methods and their relations
to atmospheric precipitation.

Measurements of the cst3? content of people and of food-

stuffs indicate that this nuclide is unlikely to be a
;
decisive factor in the long-term hazards from Weapons) 39
testing and reactor waste disposal.
The amount of Cs

now present in the population of the United States

averages 0.006 microcurie and shows no marked dependence
on geographic logation.
The average radiation dose
received from Cs
is one-twentieth of that received

from natural radiopotassium and 1 percent of the average
total dose from all natural sources.

Because of the

short biological half-life of cesium of about9ot0 days,
it does not accumulate in the body as does Sr?
The

study of the distribution of Csl3/
is being continued to
furnish information on the mechanisms of the fallout
process and provide a measure of the rate of fallout and

of stratospheric storage.
