Hill等人报告了切尔诺贝利反应堆事故后一段时期的~(131)I测量结果。作者从意大利Genoa地区死于事故的51名成年人尸检中获得的甲状腺样品,直接测量了~(131)I活性。采样是在1986年5月3日开始的,即放射性落下灰到达该地区后2天和大量降落前一天。将甲状腺样品置入一个联接有1024道谱仪的NaI(Tl)井型探头中测量其放射性,并测量相同几何位置的~(131)I标准源放射性作为对照。个体间的差异大体反映了受到不同的照射。放射性落下灰到达初期,就测到高水平的~(131)I。随
Hill et al. Reported ~ (131) I measurements over a period of time after the Chernobyl reactor accident. The authors measured 131I activity directly from thyroid samples obtained from an autopsy of 51 adult adults who died of an accident in Genoa, Italy. Sampling took place on May 3, 1986, two days after the radioactive ash had arrived in the area and one day before the massive fall. Thyroid samples were measured for radioactivity in a NaI (Tl) well type probe coupled to a 1024 spectrometer and the radioactivity of ~ (131) I standard source at the same geometric location was measured as a control. The differences between individuals generally reflect different exposures. Radioactive fall ash arrived early, it measured a high level of ~ (131) I. With
