It is shown that revelation of “new” tracks by prolonged etching is a minor effect, and that the effects of the minimum observable track length and differing distributions of etched track length in different surfaces are the major causes of values of <em>G</em> ≫ 0.5. It is also shown experimentally that with modern equipment, which allows tracks of ∼0.5 μm length to be resolved, it is possible to obtain values of <em>G</em> ∼ 0.5, and the use of this “ideal” value introduces little error in the final analysis. The behaviour of some other geometry ratios is also discussed.</p></div>","PeriodicalId":100974,"journal":{"name":"Nuclear Track Detection","volume":"2 4","pages":"Pages 207-213"},"PeriodicalIF":0.0,"publicationDate":"1978-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/0145-224X(78)90025-X","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90997707","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}
