Trends and issues in internal dosimetry, 2; Development of internal dose calculation code in JAEA and issues in internal dosimetry

Manabe, Kentaro   

JAEA has been developing the Internal Dose Calculation Code, IDCC, as a technical basis for incorporating the 2007 Recommendations of the International Commission on Radiological Protection (ICRP) into the Japanese regulatory standards for protection against internal exposure. Currently, all of the systemic kinetic models and radiation absorption fraction data are introduced to IDCC to perform the internal dose assessment for occupational exposure. In this presentation, we will report on the backgrounds, current status, and future plans of IDCC development, and raise the issue of the need for standard models for retrospective dose assessment in the event of a radiation accident.
