Radiation effects from the atomic bomb extended beyond
the acute disorders that appeared immediately after the
bombing. It caused various disorders for decabes and con-
tinues to threaten the health of survivors today.
In early 1946, burn scars on some survivors began to
swell into keloids. In-utero survivors were born with micro-
cephaly, with its attendant mental and physical disorders.
Starting around 1950, the number of leukemia patients
soared. Starting around 1955, the incidence of thyroid,
breast, lung and other cancers increased. Even today, ex-
planations of the effects of radiation over the years are in-
adequate. Research and survey efforts continue.
