The development of Ceric-cerous technique is traced from 1980 to the present day with reference to its use as processing control dosimeter. To the same purpose the residual TL of the 280°C peak of natural quartz is suggested for the first time to extend its gamma-ray response up to 100 kGy. The factors affecting on measurement accuracy for both systems are improved to satisfy the requirements for quality control of irradiated products. Es wird ein Uberblick uber die wesentlichen dosimetrischen Eigenschajten von Cc(IV)/Ce(III)Suljaten und von naturlichen Quarz-Thermolumincszenz-Dosimetern im Bereich von 1 … 100 kGy gegeben. Die Entwicklung der Ce(IV)/Ce(III)-Technik kann bis zum Jahr 1980 auf ihre Eignung als Prozeβkontroll-Dosimeter zuruckverfolgt werden. Fur den gleichen Zweck wird die Rest-Thermolumineszenz beim 280 °C-Peak des Natur-Quarzes fur eine Bereichserweit...","PeriodicalId":404027,"journal":{"name":"November 1986","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1986-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133934357","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}

Neutron radiography can thus be a valuable nondestructive method for the detection and quantitative evaluation of corrosion on aluminium structures.
