Reply to the Comments by Mortazavi and Doss on “Solid Cancer Incidence among the Life Span Study of Atomic Bomb Survivors: 1958–2009” (Radiat Res 2017; 187:513–537)

Summary: The study found a linear dose-response relationship for urinary tract cancer (UTC) in atomic bomb survivors, with radiation exposure contributing to approximately 18% of UTC cases. Kidney cancer was significantly influenced by smoking, but had weak associations with radiation exposure.
