Abstract

Levels of 137Cs and 134Cs resulting from the Chernobyl nuclear accident were studied in 195 birds that winter in two regions of Spain. Only five of the 12 species examined were contaminated. The average values for 137Cs vary between 1.6 and 41 Bq kg-1 fresh. In particular, the contamination for song-thrushes (Turdus philomelos) are compared between the regions of Extremadura and Valencia, 350 km east of Extremadura at the same latitude. The results show that the contamination of birds wintering in Spain decreases from east to west. The whole-body dose commitment for humans consuming these contaminated birds was calculated. The values are well below the established ICRP guideline.

摘要

对在西班牙两个地区越冬的195只鸟类体内切尔诺贝利核事故产生的¹³⁷Cs和¹³⁴Cs水平进行了研究。在所检测的12个物种中，只有5个受到了污染。¹³⁷Cs的平均值在1.6至41贝克勒尔/千克鲜重之间变化。特别地，对歌鸫（欧歌鸫）在埃斯特雷马杜拉地区和位于埃斯特雷马杜拉以东350公里、同一纬度的巴伦西亚地区的污染情况进行了比较。结果表明，在西班牙越冬鸟类的污染程度从东向西递减。计算了食用这些受污染鸟类的人类的全身剂量承诺。这些值远低于国际辐射防护委员会制定的指导方针。
