The concentration of antimony in nail and hair was determined by thermal neutron activation analysis. Samples were collected from the workers of an antimony refinery, inhabitants near the refinery, and residents in control area. They were irradiated by Kyoto University 5 000 kW Reactor for 1 h, and cooled for 30 to 100 days. After cooling, the concentration of Sb in nail and hair was estimated by measuring the intensity of gamma-ray from 124Sb of the samples, then the samples were washed by 0.1% aqueous solution of nonionic surface active agent in an ultrasonic cleaner. The gamma-ray spectrometry was done again (after washing). The concentration of Sb in nail before washing was 730 ppm for the workers, 2.46 ppm for habitants near the refinery, and 0.19 ppm for the control; after washing, it became 230 ppm for the workers, 0.63 ppm for habitants, and 0.09 ppm for the control. The concentration of Sb in hair before and after washing was 222 ppm and 196 ppm for the workers, and 0.21 ppm and 0.15 ppm for the control, respectively.
采用热中子活化分析法测定指甲和头发中的锑浓度。样本采集自一家锑冶炼厂的工人、冶炼厂附近的居民以及对照区域的居民。他们在京都大学5000千瓦反应堆中辐照1小时，然后冷却30至100天。冷却后，通过测量样本中124Sb的γ射线强度来估算指甲和头发中的锑浓度，之后将样本在超声波清洗器中用0.1%的非离子表面活性剂水溶液清洗。（清洗后）再次进行γ射线光谱分析。清洗前，工人指甲中的锑浓度为730 ppm，冶炼厂附近居民为2.46 ppm，对照区域居民为0.19 ppm；清洗后，工人指甲中的锑浓度变为230 ppm，居民为0.63 ppm，对照区域居民为0.09 ppm。工人头发清洗前后的锑浓度分别为222 ppm和196 ppm，对照区域居民头发清洗前后的锑浓度分别为0.21 ppm和0.15 ppm。
