These claims prompted a review of archival records of the Australian Radiation Laboratory (ARL) that are held by the Australian Archives pertaining to the medical uses of radio-isotopes during the period 1947-73. The material examined indicates that the procurement, distribution, and therapeutic and diagnostic uses of radio-isotopes were stringently controlled by the Radio-isotopes Standing committee (RSC) until 1973, when the responsibility of regulation of medical uses of radio-isotopes passed to the Therapeutic Goods Administration. On the basis of available information it appears that the claims made by the media that many Australians were subjected to unconscionable medical experiments are unjustified. A full report has been released by the Commonwealth Minister for Human Services and Health. The following is an abridged version of that report, detailing some of the more contentious uses of radio-isotopes for medical purposes in Australia during the period 1947-73.</p>","PeriodicalId":75572,"journal":{"name":"Australasian radiology","volume":"41 2","pages":"211-9"},"PeriodicalIF":0.0,"publicationDate":"1997-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"20101395","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}

Skin dose from radiotherapy X-ray beams: the influence of energy. 放射治疗x射线的皮肤剂量:能量的影响。

Higher energy beams do not necessarily produce lower surface and basal cell layer doses due to this electron contamination. For a 5 x 5 cm field size the surface doses for 6 MVp and 18 MVp X-ray beams are 10% and 7% of their respective maxima. However, at a field size of 40 x 40 cm the percentage surface dose is 42% for both 6 MVp and 18 MVp beams. The introduction of beam modifying devices such block trays can further reduce the skin-sparing advantages of high energy photon beams. Using a 10 mm perspex block tray, the surface doses for 6 MVp and 18 MVp beams with a 5 x 5 cm field size are 10% and 8%, respectively. At 40 x 40 cm, surface doses are 61% and 63% for 6 MVp and 18 MVp beams, respectively. This trend is followed at the basal cell layer depth. At a depth of 1 mm, 18 MVp beam doses are always at least 5% smaller than 6 MVp doses for the same depth at all field sizes when normalized to their respective Dmax values. Results have shown that higher energy photon beams produce a negligible reduction of the delivered dose to the basal cell layer (0.1 mm). Only a small increase in skin sparing is seen at the dermal layer (1 mm), which can be negated by the increased exit dose from an opposing field.</p>","PeriodicalId":75572,"journal":{"name":"Australasian radiology","volume":"41 2","pages":"148-50"},"PeriodicalIF":0.0,"publicationDate":"1997-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"20101552","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}
