The transit of an air mass containing radioactive gas released from the Three Mile Island reactor was recorded in Albany, New York, by measuring xenon-133. These measurements provide an evaluation of Three Mile Island effluents to distances greater than 100 kilometers. Two independent techniques identified xenon-133 in ambient air at concentrations as high as 3900 picocuries per cubic meter. The local gamma-ray whole-body dose from the passing radioactivity amounted to 0.004 millirem, or 0.004 percent of the annual dose from natural sources.
通过测量氙-133，在纽约州奥尔巴尼记录了含有三里岛反应堆释放的放射性气体的气团过境情况。这些测量结果评估了三里岛排放物扩散到100多公里以外的情况。两种独立技术在环境空气中检测到了氙-133，其浓度高达每立方米3900皮居里。过往放射性物质产生的局部全身伽马射线剂量为0.004毫雷姆，即天然本底辐射年剂量的0.004%。
