摘要
某农科院辐照室利用钴源对农产品进行杀菌消毒等工艺处理,在农业应用上非常见成效。但是60Co属于高毒性核素,一旦泄露,后果将不堪设想,所以有必要对辐照室内外环境进行辐射监测和辐射安全评价,以确保工作人员和周围居民的身体健康和生命安全。在辐照室周围布置了6个监测点,利用射线检测仪对这些点进行监测,结果表明不论源是否处于工作状态,农科院辐照室的设计多是安全可靠的,正常运行状态下,对周围环境不会造成不良影响。此外,鉴于60Co自身特性,还概述了外照射的防护措施。
60Co source is applied in the process such as sterilizing agricultural products in irradiation room of some Academy of Agricultural Sciences,which is very effective in agricultural applications.However,60Co is highly toxic,once the leak,the consequences would be disastrous.So it is necessary to summarize the radiation protection and safety evaluation of the irradiation room indoor and outdoor,to ensure the health and lives of the staff and the surrounding population.The radiation detectors monitor six points around the irradiation room.Results show that design of irradiation room of Academy of Agricultural Sciences are mostly safe and reliable,regardless of the source in working condition.And consequences also show 60Co source in the normal operating will not put adverse effects on the surrounding environment.In addition,the outer radiation protective measures are also outlined,in view of 60Co own identity.
