Dissection of GBZ 97-2017 Judgment standard for occupational radiogenic neoplasms—A computer software for occupational radiogenic neoplasm judgment

As the leading institute of the draft group, the Institute of Radiation Medicine, Chinese Academy of Medical Sciences drafted "Judgment standard for occupational radiogenic neoplasms" GBZ 97-2017 and developed its software. This paper introduces the calculation logic of the software, as follow: the methodology of probability of causation in GBZ 97-2017, including the theoretical basis of rationality for using causation probability for the judgment of radiogenic neoplasms; Japanese risk model in estimating cancer risks induced by ionizing radiation and risk transfer model from Japanese population to Chinese population; and use of smoking correction factors to eliminate smoking attribution to lung cancer. This paper introduces the general situation of GBZ 97-2017 software development and its deficiencies and suggests the development of an online software.
