This study was performed with four different radioisotopes;(18)F, (99m)Tc, (124)I and (131)I. (18)F results showed a decrease in dose with 0.5-mm Pb shielding but the reduction provided does not warrant its use clinically. (124)I testing demonstrated that dose enhancement can occur in greater shield thicknesses. PET isotope (124)I can be adequately shielded using 0.25-mm Pb equivalent aprons but any higher thickness increase the wearer's dose. As a result more shielding does not always equal more protection. The (131)I test showed that no dose reduction occurred, even when tested with up to 1.25-mm Pb equivalent shielding. Novel radioisotopes being used in the laboratory and clinic should be individually tested as each requires specific shielding testing. | Gov't Doc #: | 25848112 | URI: | https://ahro.austin.org.au/austinjspui/handle/1/12723 | DOI: | 10.1093/rpd/ncv065 | Journal: | Radiation protection dosimetry | URL: | https://pubmed.ncbi.nlm.nih.gov/25848112 | Type: | Journal Article |
