Cesium 137 is present in worldwide. To evaluate its deposition in the Brazilian state of Alagoas a total of 41 samples were collected by the Geological Survey of Brazil, then processed and analyzed by gamma-ray spectrometry with hyperpure germanium detectors. The activity concentration varied from (0.3 ± 0.1) Bq/kg to (1.1 ± 0.4) Bq/kg. The present study shows that the Borborema Plateau acts as a natural barrier to rainfall, favoring the deposition of 137Cs on the local soil.

巴西阿拉戈斯州土壤中的 137Cs 活性浓度。
铯 137 存在于世界各地。为了评估其在巴西阿拉戈斯州的沉积，巴西地质调查局共收集了 41 个样品，然后通过伽马射线光谱法和超纯锗探测器进行处理和分析。活性浓度从 (0.3 ± 0.1) Bq/kg 到 (1.1 ± 0.4) Bq/kg。目前的研究表明，Borborema 高原作为降雨的天然屏障，有利于137 Cs 在当地土壤上的沉积。
