Bomb energy, detonation altitude, ang atiospueric
conditions have significant influerces on the mechanisa, rate, and pattern of fallout. These variables are discussed. Also gensidered is the possi-
bility of an intolerable Kr°/
concentration in the
atmosphere fron nuclear power plants.

Radioactivity of various parts of rice seeds cropped
in 1954 was detd. and compared with that of 1953.
Radioactivity due to K4+O was established as total
count of the asl. and was subtracted for correction.
None of rice seeds in 1953 showed excess radioactivi-
ty.
With the seeds in 195% the following
were obtained:
3-6 cop.m./2 g;
polished rice 0;
results
unhulled rice 3-6 c.p. neJB3
chaff
unpolished ite 0-0.3 c.p.m/8 g.3
rice bran 0.
This radioactivity
is thought to come from the rain, adherent to the
chaff, but not from soil contamination.
