epilation. These lesions healed and hair regrew normally within several
months. Radiochemical urine analyses revealed that measurable amounts
of radionuclides, including /sup 131/I, were absorbed internally from
ingestion of contaminated food and water and from inhalation.
No acute
effects due to this internal exposure were seen. Late thyroid effects
from radioiodine absorption are described. Follow-up examinations have
revealed, except for one fatal case of leukemia and extensive thyroid
lesions, only a few findings that might be related to radiation
exposure. A group of more than 200 Rongelap people who were relatives
of exposed people, but had been away from the island at the time of the
accident, moved back with the exposed people to their home island in
1957 and have served as an ideal comparison population for the studies.
Results of medical examinations carried out on these populations for
the past 22 years are reviewed.;

Abstract: The study related to the natural radioactivity in rain did not
make rapid progress in the first half of the 20th century tholigh the
1900. In the latter half of the century, however, a large amount of
fission products by nuclear experiments caused the rapid progress in
the research on artificial radioactivity in rain. The amount of fission
products in rain water as well as in atmosphere has been decreasing
recently, and many scholars treat the research on fall-out lightly. The
radioactivity in rain owing to the nuclear experiments by China and
France is still considerably strong, and a lot of interesting results
have been obtained by the study applying the artificial radioactive
elements in rain water as the tracer.
radioactivity in rain,
/sup 210/Pb,
Concerning the natural
/sup 210/Bi and /sup 210/Po, the
long life decay products of radon, may play extremely important role in
the field of meteorology and geochemistry in future, as natural
radioactive tracers existing in atmosphere in high concentration. ;
