The number of mass chest x-ray examinations in Japan in 1980 was 26.6 million and the average effective dose equivalent was 26 mrem per examination. The genetically significant dose was .017 mrem per person per year, the per caput mean marrow dose was 5.9 mrem, the leukemia significant dose was 5.2 mrem and the malignancy significant dose was 2.8 mrem. The excess deaths were calculated to be 70-280 depending on the risk model used. Those would be in excess to the 3.7 million cancer deaths normally expected among the examined population. The loss of life expectancy calculated with a relative risk model was 38 yr for males and 43 yr for females due to leukemia with a latent period of 2 yr and an expression period of 25 yr, and 12 yr for males and 14 yr for females due to other cancers with a latent period of 10 yr and an expression period of lifetime in the 20-24 age group.
1980年日本进行的胸部X线大规模检查数量为2660万次，每次检查的平均有效剂量当量为26毫雷姆。遗传显著剂量为每人每年0.017毫雷姆，人均平均骨髓剂量为5.9毫雷姆，白血病显著剂量为5.2毫雷姆，恶性肿瘤显著剂量为2.8毫雷姆。根据所使用的风险模型，计算得出的超额死亡人数为70 - 280人。这些将超出受检人群中通常预期的370万例癌症死亡人数。对于20 - 24岁年龄组，使用相对风险模型计算得出，因白血病（潜伏期2年，发病期25年）导致的男性预期寿命损失为38年，女性为43年；因其他癌症（潜伏期10年，发病期为终身）导致的男性预期寿命损失为12年，女性为14年。
