CORPORATE TEXT Oesterreichischer Verband fuer Strahlenschutz (OeVS), PAGE RANGE PUB. DATE (YYMMDD) LIMITATION CODE ABSTRACT Vienna (Austria) 786-790 881100 UNL 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.
