The conclusion was that present monitoring programmes that record ambient solar UVR in a horizontal plane at different locations as input data to studies on the epidemiology of skin cancer are appropriate for obtaining a relative estimate of the population exposure in locations with different climatic conditions, providing, of course, that the outdoor exposure habits of different populations are comparable.</p>","PeriodicalId":20061,"journal":{"name":"Photo-dermatology","volume":"5 4","pages":"175-8"},"PeriodicalIF":0.0,"publicationDate":"1988-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"14359149","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}
