Increased atmospheric radioactivity after the accident in Chernobyl was first detected on air filters. Measurements were begun in Valencia on May 2, 1986, with the maximum activity being observed around May 3-4, 1986. As a consequence of this accident, annual campaigns of measurements on migrating birds (several species of aquatic birds and song-thrushes) were started. The data corresponding to the campaign immediately after the accident (1986/87) show a generalized contamination (approximately 50% of the measured specimens). Significant levels of 134Cs, 137Cs and 110Agm were found. It is important to note that 110Agm is only present in Aythya ferina. In the successive campaigns in 1988/89 and 1989/91 few samples were found to be contaminated and only 137Cs was identified. Strontium-90 was measured and identified in some specimens, mainly in their bones.
切尔诺贝利事故后大气放射性增强,最初是在空气过滤器上检测到的。1986年5月2日在巴伦西亚开始测量,1986年5月3日至4日左右观测到最大活度。这场事故导致了对候鸟(几种水鸟和歌鸫)的年度测量活动的开展。事故后紧接着的那次测量活动(1986/87年)的数据显示普遍受到污染(约50%的被测样本)。检测到了显著水平的134铯、137铯和110银-108m。需要注意的是,110银-108m仅存在于赤颈鸭中。在1988/89年和1989/91年的后续测量活动中,发现受污染的样本很少,且仅识别出了137铯。在一些样本中测量并识别出了锶-90,主要存在于它们的骨骼中。
