| 摘 要： | 利用剂量计算和风险评估模型,基于国际原子能机构(IAEA)推荐的标准数据库和日本核燃料循环开发机构(JNC)的玻璃固化体源项数据,利用程序计算了人类入侵处置库景象下的受照剂量和风险,计算结果表明:在人类入侵景象下,最大外照射剂量在10-4数量级,贡献较大的核素有126 Sn、243 Am;最大内照射剂量在101数量级,贡献较大的核素有240 Pu、241 Am、237 Np和243 Am;内照射和外照射的最大风险值在10-12数量级,远远低于其他类型风险。

| Abstract: | Based on dose calculation and risk evaluation model,the dose and risk of human intrusion scenarios were calculated with the standard method recommended by IAEA and HLW glass source database from JNC.The results showed that in human intrusion scenario,the maximum external radiation dose was in 10-4 magnitude and the largest contribution radionuclides were 126 Sn,243 Am,the maximum internal radiation dose was in 101 magnitude and the largest contribution radionuclides were 240 Pu,241 Am,237 Np,243 Am;risk value are at the level of 10-12,which is far lower than other types of risk. |
