Development of Software for Organ Dose Estimation at Radiation Emergency with Internal Contamination

At radiation emergency with heavy internal-contamination, prompt estimation of doses at specific organs is sometimes needed for planning clinical treatments. Recently developed biokinetic models of ICRP permit more realistic description of the behaviour of radionuclides in human body. This, however, has made the interpretation of bioassay data extremely difficult. Thus computer programs for implementing these models have become needed, but very few. The present work provides a PC software: MONDAL3 (Monitoring to Dose Calculation Ver.3) that enables users, even if non-specialists, to estimate readily intake of radionuclides and resulting equivalent doses in organs and effective doses at radiation emergency with internal contamination from measurement results of radioactivity in a whole body or in specific organs or in excreta.日本放射線影響学会第46回大
