Fukushima and Chernobyl are more than 7,000km apart, but Dr Mousseau andhis colleagues soon realised that the two sites had much in common. Both are in areas thathave a temperate climate with species that have similar habits and needs. And both aresurrounded by a mixture of farmland and forest. Upon closer examination the researchersfound that 14 species of bird lived in both regions, including the barn swallow, great tit,great reed warbler, buzzard and Eurasian jay. With so many similarities between the twoplaces, a comparison of the biological responses to radiation in each would surely be illuminating.

　　福岛和切尔诺贝利相距7，000余公里，不过Mousseau和同事们很快发现，两地的鸟类种群有共同之处。两地均属温带气候，周围环绕着农田和森林，鸟类的习性和需求相似。经过进一步调查，研究人员发现两地有14种相同的鸟类，包括家燕、大山雀、大苇莺、?⑺裳弧＜热磺榭鋈绱讼嗨疲?冉狭降厣?锒院朔?涞姆从匀挥本哂衅舴⒁庖濉?/p

　　To do this, during July 2011, the researchers counted and identified birds at 300 locationsnear Fukushima that had radiation levels as low as 0.5 microsieverts per hour and as high as35 .Then they compared these results to bird data collected in areas that had the same range ofradiation levels near Chernobyl between 2006 and 2009.

　　2011年7月，研究人员清点并鉴定了福岛核电站附近300个地点的鸟类。这些地点的辐射水平低至0.5毫西弗/小时，高至35毫西弗/小时。作为对照，牙医给患者拍X光片的辐射量很少超过0.05毫西弗。他们将结果与在切尔诺贝利周围采集的数据进行了比对。这些数据采集于 2006年~2009年间，采集地点的辐射水平与福岛相似。
