The present study demonstrates an increased prevalence of malignant lymphoma and multiple myeloma in survivors of the atomic bomb in Hiroshima exposed to 100 rad or more; a similar relationship is not evident in Nagasaki. This apparent discrepancy is tentatively attributed to known physical differences in the radiation spectrum emitted by the 2 bombs and/or biological differences between the inhabitants of Hiroshima and Nagasaki. Other observations of interest include the following: the risk of developing lymphoma or multiple myeloma appears to be greater in persons exposed at less than 25 years of age than in people who were 25 or more years old at the time of the bomb; the appearance time is shorter in the younger age group exposed to 100 rad or more in comparison with less heavily exposed persons, and also in comparison with heavily exposed persons in the older age groups.
