The number of persons evacuated after Chernobyl
accident is reported to be about 135000, which is almost
comparable to that of the exposed to the atomic bombings
at Hiroshima and Nagasaki in 1945. However, in case of
atomic bombing, the whole body gamma and neutron
radiation is received in an extremely short time,
possibly of the order of some nano seconds. In addition,
they received strong effects of blast waves, thermal
radiation, and other toxic chemicals released to the
environment due to destruction of various facilities by
bombing. In case of Chernobyl accident, the whole body
gamma radiation is received in a much longer time,
possibly of the order of some hours,
by the evacuees.
The dose rate would be greatly different.
respect,
In this
the accidental exposure to the strongly
radioactive fallout at Bikini accident in 1954 may be
more similar to the case of Chernobyl accident. The
author makes some comparison of these cases, because of
his involvement in investigation of the past radioactive
fallout as observed in Japan. The radioactivity due to
Chernobyl accident reached Japan at about 8 days after
the accident.
The volatile radionuclides
such as
I
131,
Cs 137 were predominant. The radioactivity ratio Cs
137/Cs 134 was about 2. In case of Bikini H-bomb test,
all radioactivities are released instantaneously and
radioactivities of non-volatile as well as volatile
elements were observed. 2 figs.
