Computer program for calculation of in-utero doses from anthropogenic radionuclides

Introduction: A computer program was created to calculate intrauterine radiation doses, "FetusDose", in the frame of the dosimetric support of epidemiological studies conducted for the population of the Ural region. Summary: The paper presents the method and describes the principle of organization and functionality of the computer program. The software is designed to calculate trimester and total doses accumulated in the active marrow and extra-skeletal tissues of the fetus when it is irradiated with anthropogenic radionuclides that have accidentally contaminated the environment. When calculating doses, two radiation scenarios are considered: the external one from soil contaminated with gamma-emitters ( 95 Zr, 95 Nb, 144 Ce/ 144 Pr/ 144 mPr, 106 Ru/ 106 Rh, 91 Y and 137 Cs/ 137 mBa) and the internal one from oral intake of radionuclides ( 90 Sr/ 90 Y, 89 Sr, 137 Cs/ 137 mBa and 144 Ce/ 144 Pr/ 144 mPr) into the mother's body with food and water. Conclusion: The software can be used both to study the consequences of radiation incidents that have already occurred, and to predict the radiation exposure from potential threats. The program will also be useful for educational purposes in the training of specialists in the field of radiobiology and dosimetry.
