Internal dose calculation code in line with the ICRP 2007 Recommendations

Manabe, Kentaro   ; Takahashi, Fumiaki  

The Atomic Energy Agency has developed a code for internal dose calculation as a fundamental technology for introduction of the 2007 Recommendations of the International Commission on Radiological Protection into the regulatory standards for internal exposure. The code provides two functions: calculation of committed effective doses for unit intake of radionuclides and estimation of intakes of radionuclides from individual monitoring data. The two functions are integrated by a graphical user interface. We will introduce an overview of the code, the status of implementation of biokinetic models published in April 2022, and a plan of integration of radiation absorption data based on the physique of reference Asian.
