【摘要】 目的了解苏州大学独墅湖校区天然放射性水平。方法采集该区域不同水体、土壤、食品,采用BH1216型低本底α、β放射性测量仪,监测样品总α、总β放射性水平。结果自来水、地表水、土壤总α水平分别是0.061Bq/L、0.104Bq/L、1708Bq/kg,总β分别是0.183Bq/L、0.319Bq/L、780Bq/kg,韭菜、土豆、茭白、猪肉、鱼肉总α水平分别是1.83、2.36、1.84、3.40、3.76Bq/kg,鱼骨头总α水平低于监测下限,总β水平分别是70.81、96.71、60.63、86.20、97.51、73.94Bq/kg。结论该地区饮用水及食品总放射性均未超过相应的控制水平,地表水及土壤总放射性在正常的天然本底水平。说明该地区未受到人工放射性的污染,人居环境是健康安全的。更多还原

【Abstract】 Objective To get the message of natural radioactive level in the Dushu lake campus of Suzhou university. Methods Different types of water、soil and food in this region were collected, and then the level of total α and total β radioactivity of the sample was investigated applying model BH1216 equipment which measuring was used for low background total α and β radioactivity. Results Total α in city water, surface water and soil were 0.061 Bq/L, 0.104 Bq/L,1708 Bq/kg respectively, total β were 0.183 Bq/L, 0.319 Bq/L, 780 Bq/kg respectively, total α in chive,potato, water bamboo, pork, fish were 1.83,2.36,1.84,3.40,3.76 Bq/kg respectively, total α of Fish bone was at infra-monitoring lower limit, total β in them were 70.81,96.71,60.63,86.20,97.51,73.94 Bq/kg respectively. Conclusion The results of the investigation display that the total radioactivity in drinking water and food don’t exceed limits, in surface water and soil is at normal natural background. It can be concluded that this region has not been polluted by the artificial radioactivity and the environment of human habitation is healthy and safe.更多还原
