Detailed external measurements were made of internally deposited 241Am in a nuclear chemical operator involved in an americium exposure accident at the Hanford plant. Despite some interference from high-level external contamination, quantitative measurements of the 241Am content in the lung, liver and bones were made starting on the third day after the accident. The rate of excretion of 241Am from these organs was determined. The 241Am embedded in the skin of the face and head was carefully mapped. The distribution over the total length of the body was also determined. Linear and rectilinear scanners, gamma cameras, large and small scintillation detectors, proportional counters, and Si(Li) and intrinsic germanium detectors were used to evaluate the internal deposition. Methods of calibration for quantitative measurement included simulation of the 241Am activity in both phantom and cadaver parts.
对一名参与汉福德工厂镅暴露事故的核化学操作员体内沉积的241Am进行了详细的外部测量。尽管受到高水平外部污染的一些干扰，但在事故发生后的第三天开始对肺、肝和骨骼中的241Am含量进行了定量测量。测定了这些器官中241Am的排泄率。仔细绘制了嵌入面部和头部皮肤的241Am分布图。还确定了其在身体全长上的分布。使用线性和直线扫描仪、伽马相机、大小闪烁探测器、正比计数器以及硅（锂）探测器和本征锗探测器来评估体内沉积情况。定量测量的校准方法包括在体模和尸体部分模拟241Am活性。
