The results indicated that its sensitivity to gamma-rays is 17.6 m V/kGY up to 60 kGy, and its sensitivity reduces to 10-17 mV/kGy from 70 kGy up to 700 kGy within an error of ±7%, while its response to fast fission neutrons is G7 mV/Gy. Factors affecting dosimeter reading such as dosimeter reading at high temperature, dosimeter annealing and reusability are also studied. The system teas used for gamma-ray and neutron dosimetry around high level gamma-ray source, reactor ducted concrete shield, and it is also examined for reactor core dosimetry.","PeriodicalId":230732,"journal":{"name":"November 1981","volume":"200 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1981-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133883360","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
