One of the largest sources data on radiation exposure in humans is study atomic bomb survivors at Hiroshima and Nagasaki, Japan performed by Radiation Effects Research Foundation (RERF). As part their retrospective dosimetry efforts for survivors, RERF published two core systems: Dosimetry System 1986 (DS86) 2002 (DS02). Due to computing limitations time, only three stylized phantoms (an infant, child adult) were used DS86 DS02 represent entire Japanese population. In this study, we sought...
An important cohort of the atomic bomb survivors are women who were pregnant when exposed to photon and neutron fields at both Hiroshima Nagasaki, as well their children in utero. Estimates organ dose developing fetus allow for development dose-dependent gestational age-dependent models deterministic (e.g., malformation) stochastic leukemia) risk utero exposure. To date, 1986 2002 dosimetry systems Radiation Effects Research Foundation have utilized uterine wall non-pregnant adult female a...
Abstract The radiation exposure estimates for the atomic bomb survivors at Hiroshima and Nagasaki have evolved over past several decades, reflecting a constant strive by Radiation Effects Research Foundation (RERF) to provide thorough dosimetry their cohort. Recently, working group has introduced new series of anatomical models, called J45 phantom series, which improves upon those currently used RERF through greater age resolution, sex distinction, realism, organ dose availability. To...
Owing to recent advances in computational dosimetry tools, an update is warranted for the system atomic bomb survivors that was established by Joint U.S.Japan Working Group on Reassessment of Atomic Bomb Dosimetry 2002 (DS02). The DS02 system, and its predecessor, DS86, at Radiation Effects Research Foundation (RERF), are based adjoint Monte Carlo particle transport simulations coupled with stylized human phantoms. In our previous studies, we developed J45 series voxel phantoms...
Organ dosimetry data of the atomic bomb survivors and resulting cancer risk models derived from these are currently assessed within DS02 system developed through Joint US-Japan Dosimetry Working Group. In DS02, anatomical survivor limited to three hermaphroditic stylized phantoms-an adult (55 kg), a child (19.8 an infant (9.7 kg)-that were originally designed for preceding DS86 system. As such, organ doses needed assessment in-utero risks fetus have continued rely upon use uterine wall in...
