On the basis of the increase of cobalt source intensity,dose distribution,shielding safety of structure and the relation between deepth of water well and Storage of cobalt source were studied,and the technical of cobalt source store in water trough was proposed to intensify shielding effect against γ radiation with crevice of trough body and water deepth .The results indicated that:(i) when the intesity of cobalt source increased from 1.11×10 15 Bq to 3.77×10 15 Bq,protection survey was in background...

On the basis of the increase of cobalt source intensity,dose distribution,shielding safety of structure and the relation between deepth of water well and Storage of cobalt source were studied,and the technical of cobalt source store in water trough was proposed to intensify shielding effect against γ radiation with crevice of trough body and water deepth .The results indicated that:(i) when the intesity of cobalt source increased from 1.11×10 15 Bq to 3.77×10 15 Bq,protection survey was in background range without increasing of γ radiation level in the enviroment;(ii)both irradiation precision to scientific research samples and the uniformity required by irradiation dose of merchandise were obtained by this appliance.This study was expected to provide a comparison for the technical transformation of similar irradiation field.

为增大钴源强度, 研究了γ辐照场的剂量分布和建筑物的屏蔽安全性以及水井深度与钴源贮量的关系, 并提出一种槽式贮源方法, 以利用其槽体狭缝和水层厚度来增加γ射线的屏蔽效果。结果表明: (1)钴源从111×1015 Bq 增至377×1015 Bq, 防护监测结果在本底范围, 未造成环境γ辐射水平增高; (2) 既满足科研样品的照射精度又符合商品辐照剂量的均匀性要求。

According to the data of investigation in Guangdong Province and the results of lightning tests on high-rise communication building in Changsha City, this paper makes a discussion on 7 problems including attractive radius, shielding effectiveness, shielding angle, frame impedance, radiation resistance, transfer potential and earthing system.

依据在广东地区的调查资料和长沙高层建筑通信大楼的雷击试验结果,把高层建筑物作为一个防雷系统工程来研究,对吸引半径、屏蔽效果、屏蔽角、框架阻抗、幅射电阻、转移电位和接地系统等7个问题进行了分析计算。得出以下结论:高层建筑物的吸引半径较大,其接闪装置宜用吸引上行雷的垂直避雷针;高层建筑物的屏蔽角不大,与其相邻的建筑物也应考虑必要的防雷保护措施;钢筋框架阻抗。辐射电阻不可忽视,沿高度敷设金属管线时,应按照低频耦合、电耦合和高频耦合的特性设计布线;金属管线产生的转移电位会通过引出、引进的金属管线传输到邻近的建筑物;接地系统由不同用途的接地形式构成。

Air exchange rates and interior flowing of a two-units building is determinated using tracer-gas dilution method in this paper in order to creat a actual determinaton method and get some useful data at the same time. The results indicate that the selected building has satisfactiory air exchange rates and interior flowing, however, low shield cability. This work can offer a reference for the studying of indoor air quality and shield factor of building.

采用示踪气体稀释法对选定的双单元建筑物的换气速度和内部流动进行了测量,以期建立一种实际测量的方法,同时获得一些有用的数据。测量结果表明,选定的建筑物具有令人满意的换气速度,内部流通良好,可满足室内空气质量的要求,但对污染事故的屏蔽能力较差。本工作可以为研究室内空气质量和建筑物屏蔽因子提供一些借鉴。
