Development of Internal Dose Calculation Code (IDCC)

We have developed an internal dose assessment code (IDCC) based on the latest dose assessment methods in accordance with the ICRP 2007 Recommendations. This code enables calculation of effective dose coefficients and intake estimation from individual monitoring results for all radioactive nuclides including short-lived nuclides. The validity of the code has been confirmed through comparisons with the dose coefficient database published by the ICRP and multiple literature examples. We plan to enhance the code for evaluating public exposure, and it is expected to contribute to the revision of regulatory standards for radiation protection and serve as a practical dose assessment tool based on new standards.
