Incidence of leukemia among atomc bomb survivors in relation to neutron and gamma dose, Hiroshmia and Nagasaki, 1950--71 (in Japanese and English)

Technical Report ·
OSTI ID:6096065
The incidence of leukemia during 1950--71 in the fixed mortality sample of atomic bomb survivors in Hiroshima and Nagasaki has been analyzed as a function of individual gamma and neutron kerma and marrow dose. Two dose reponse models were tested for each of acute leukemia, chronic granulocytic leukemia, and all types of leukemia, respectively. Each model postulates that leukemia incidence depends upon the sum of the separate risks imposed by the gamma ray and neutron doses; in Model I both are assumed to be directly proportional to the respective doses, while Model II assumes that while the risk from neutrons is directly proportional to the dose, the risk from gamma rays is proportional to dose-squared. Weighted regression analyses were performed for each model.
