目标 2011 年 3 月 11 日日本东部发生大地震后，福岛第一核电站 (FDNPP) 受损的反应堆向环境中释放出大量放射性物质。 FDNPP事故后，首次在暴露于放射性物质的野生日本猴的肌肉样本中检测到放射性铯，并且还报告了血液学影响、头部大小变化和体重增加延迟，但人们对Cs-137在野生日本猴器官和组织中的分布知之甚少。结果 2012 年 7 月至 8 月期间捕获的福岛市森林地区的 10 只野生日本猴的各个器官和组织样本中检测到了 Cs-137。在肌肉、大脑、心脏、肾脏、肝脏、肺和脾脏中，肌肉的 Cs-137 浓度最高，大脑的 Cs-137 浓度最低。肌肉、脑、心脏、肾、肝、肺和脾中 Cs-137 的浓度（平均值 +/- SD）分别为 77 +/- 66、26 +/- 22、41 +/- 35、49 +/- 41、41 +/- 38、53 +/- 41 和 53 +/- 51 Bq/kg。这些结果可以帮助我们了解长期体内辐射暴露对非人类灵长类动物的生物效应。
Objectives Following the massive earthquake that struck eastern Japan on March 11, 2011, a large amount of radioactive material was released into the environment from the damaged reactor of the Fukushima Daiichi Nuclear Power Plant (FDNPP). After the FDNPP accident, radiocaesium was first detected in muscle samples from wild Japanese monkeys exposed to radioactive materials, and haematologic effects, changes in head size, and delayed body weight gain were also reported, but little is known about the distribution of Cs-137 in the organs and tissues of wild Japanese monkeys. Results We detected the Cs-137 in various organ and tissue samples of 10 wild Japanese monkeys inhabiting the forested areas of Fukushima City that were captured between July and August 2012. Among muscle, brain, heart, kidney, liver, lung, and spleen, muscle exhibited the highest and the brain the lowest Cs-137 concentration. The concentration (mean +/- SD) of Cs-137 in muscle, brain, heart, kidney, liver, lung, and spleen was 77 +/- 66, 26 +/- 22, 41 +/- 35, 49 +/- 41, 41 +/- 38, 53 +/- 41, and 53 +/- 51 Bq/kg, respectively. These results can help us understand the biological effects of long-term internal radiation exposure in non-human primates.
