This project is intended to investigate effects of industrial waste that is called Amang and known as by-product material including radioactive elements from tin mines in Malaysia and may cause trouble in human risk of inhabitants nearby. For precise measurement of the material we have developed a highly sensitive Ge-NaI anti-coincidence gamma-ray measurement system. By means of this, we have measure the radio-activities of Amang and, in addition, environmental radiation intensities of inhabit area and wide area of Malay Peninsula, I.e. along a route of Butterworth-Ipoh-Kuala Lumpur-Johor Bahru. The environmental radiation from rocks sampled in Tokushima has been also measured and compared with the Amang intensities to discuss the effects to human risks. Although the radioactivity of Amang has been observed to be rather high, the irradiation due to deposited Amang may not be so large. For the next stage, it should be studied elution of radioactive substances to environment (such as water, soil, and so on).

该项目旨在调查工业废物的影响，这些废物被称为Amang，被称为副产品材料，包括来自马来西亚锡矿的放射性元素，可能对附近居民的人类风险造成麻烦。为了对材料进行精确测量，我们研制了一套高灵敏度的Ge-NaI反符合γ射线测量系统。利用这一方法，我们测量了阿曼的放射性活度，并测量了马来半岛居民区和广大地区，即沿着巴特寮-怡保-吉隆坡-新山一条路线的环境辐射强度。还测量了在德岛采样的岩石的环境辐射，并与Amang强度进行了比较，以讨论对人类风险的影响。虽然已观察到Amang的放射性相当高，但由于沉积Amang而产生的辐照可能不会如此大。下一步应研究放射性物质向环境（如水、土壤等）的洗脱。
