放射源

With the development in nucleus technology application,radiation source amount and eradiation accident both increased.

随着核技术应用领域的逐步扩展、放射源数量的增多及辐射事故突发频率的提高，2003年《中华人民共和国放射性污染防治法》发布并实施，该法明确了环境保护行政主管部门对放射源实行统一监督管理的职能。

This paper focuses on the application of the methods developed in ISAM to the Borehole Safety Assessment which is based on the Borehole Disposal Concept of Nuclear Energy Company of South African.The hypothetical geosphere and biosphere characteristics for the safety assessment are derived from the radioactive waste disposal site in northwestern China.

本文采用ISAM中开发的评价方法，参考南非原子能公司的钻孔设计概念，并根据我国西北放射性废物处置场的岩石圈和生物圈特性假定场址，对废放射源钻孔处置安全评价方法进行了研究，为我国废源钻孔处置的安全性提供依据。

It is estimated that the lifetime dose of radioactivity to which a person eating irradiated food could be exposed could realistically amount to no more than one-millionth of the recognised limit of average exposure of an individual to radioactivity from other sources over the same period.

据估计，人们由于吃进辐射食物所遭受的放射剂量，实际上不多于同一时期一个人平均可能遭受到的来自其它放射源的、可觉察的放射的极限的百万份之一。

The lifetime dose of radioactivity to which a person eating irradiated food could be expose d could realistically amount to one-millionth of the recognised limit of average exposure of an individual to radioactivity from other source over the same period.

人们由于吃进辐照食物所遭受的放射剂量，实际上不多于同一时期一个人平均可能遭受到的来自其它放射源的放射的可觉察的极限的百万份之一。

The lifetime dose of radioactivity to which a person eating irradiated food could be exposed could realistically amount to one-millionth of the recognised limit of average exposure of an individual to radioactivity from other source over the same period.

人们由于吃进辐照食物所遭受的放射剂量，实际上不多于同一时期一个人平均可能遭受到的来自其它放射源的放射的可觉察的极限的百万份之一。

When an operator or a maintenance worker is radiated as a result of incorrect operation, he or she may suffers from a poor health as a result of the radiation hazard.

设备检修时含放射源仪表的拆除、安装、铅罐活门的关闭、开启，均要有专人负责，进行严格登记，并要有放射卫生防护人员现场监护。

The article introduces recently some radioactive source accidents in China, and analyses the reasons of the accidents. Some important issues existed in the process of implementing new regulation were summarized, and some suggestions for managing radioactive sources are made.

本文通过介绍我国发生的一些放射源事故情况，分析事故发生的原因，总结了《放射性同位素与射线装置安全和防护条例》颁布后在实施过程中还存在的一些关键问题，提出了加强放射源管理的对策与建议。

The method of low dose and half-body irradiation as a radiotherapeutic method is safe and feasible and the radiation modality of backing on the radioactive source is more safe.

低剂量半身照射是安全可行的放射治疗方法，且背对放射源的照射方式更为安全。

This paper introduces the application of integrated geophysical investigation, including high precision magnetic, multielectrode method and GPR , to systematically detect a radioactive material source sealed in lead container stored in a chamber buried underground,which has been missed.

采用综合地球物理勘查技术，包括高精度磁测、高密度电法和地质雷达对某处遗留于地下的铅封放射源进行了系统探查，对所获得的各类异常数据进行了分析处理，并指出了放射源所在的具体空间位置。

The contribution of extracellular radionuclides has not been carried out because it can be calculated and added to the S-values according to conventional MIRD method.

对于多细胞群中的某个细胞，吸收剂量的贡献剂量主要包括靶细胞自身的放射源和周围细胞内的放射源。细胞间质中的放射源和光子的剂量贡献可以用MIRD方法计算。

Finally, according to market conditions and market products this article paper analyzes the trends in the development of camera technology, and designs a color night vision camera.

最后根据市场情况和市面上产品的情况分析了摄像机技术的发展趋势，并设计了一款彩色夜视摄像机。

Only person height weeds and the fierce looks stone idles were there.

只有半人深的荒草和龇牙咧嘴的神像。
