I131 thyroid uptake after the Chernobyl's accident was sampled in a Val Pellice school. Children were grouped according to sex, age and area of residence. The procedure used in collecting data and calculating the transformation coefficients from activity counts by computer simulation is analysed, as are the errors and sensitivity of the method. The activities were then converted into doses using an intake model. The dose levels identified are lower than the estimates based on the measurement of environmental matrices. Statistical analysis revealed certain subgroups with significantly different levels of absorption: particularly groups accustomed to a different diet or living in particular areas.
切尔诺贝利事故后，在瓦尔佩利切的一所学校采集了碘-131甲状腺摄取量样本。儿童按性别、年龄和居住地区分组。分析了通过计算机模拟从活度计数收集数据和计算转换系数所使用的程序，以及该方法的误差和灵敏度。然后使用摄入模型将活度转换为剂量。确定的剂量水平低于基于环境基质测量的估计值。统计分析揭示了某些吸收水平有显著差异的亚组：特别是饮食习惯不同或居住在特定地区的群体。
