Studies of the health effects among Japanese atomic bomb survivors, including radiation-induced carcinogenesis, necessitate accurate dose estimates for individual survivors from the Hiroshima and Nagasaki bombings. Efforts towards this goal commenced shortly after the bombings in 1945, resulting in a series of dosimetry systems developed over the years. Initially, these systems were created by US military groups, followed by binational US-Japan working groups. This paper focuses on the systems created by US and binational groups, with particular emphasis on the most recent dosimetry systems: Dosimetry System 2002 (DS02) and Dosimetry System 2002 Revision 1. Furthermore, we discuss the latest advancement, the J45 phantoms, which introduces a new system of anthropomorphic phantoms for organ dose calculations and has been in development over the last few years.
