Abstract

This study is suggest the importance of a safety management system against radiation exposure by measuring the surface pollution level of toilets in the radiation management area of hospitals using open seafarers and evaluating the spread. The experiment measured 10 times in front of the toilet and the entrance before and after the start of work in 3 toilets in the radiation management area of a hospital in the metropolitan area. The measuring instruments and samples were measured using an indirect measuring smear paper and a surface contamination radiation meter. As a result of the measurement the front of the left toilet in the iodine treatment room bathroom before decontamination exceeded the legally permitted surface contamination dose. All other areas were measured below the legally permitted surface contamination dose. However even if radioactive contamination is below the allowable dose pollutants and contamination conditions must be properly identified and managed with constant attention and attention. Therefore the use of toilets in the radiation control zone must be regulated so that only patients can use them and efforts must be made to minimize the spread of surface contamination outside the toilet by allowing the use of the exclusive use of toilets.
