Radiation Safety Considerations and Clinical Advantages of Alpha-Emitting Therapy Radionuclides

Conclusion: In this study, we report data from 630 patients who were undergoing treatment with alpha-emitting isotopes 223Ra and 225Ac. While alpha emitters have ability to deliver higher internal radiation dose to the tissues exposed as compared with other unsealed radionuclides, they typically present minimal external dose rate concerns. Additionally, alpha radiation can be efficiently detected with appropriate radiation instrumentation, such as a liquid scintillation counter or ZnS probe, that should be prioritized when surveying for spills of alpha-emitters.PMID:34750237 | DOI:10.2967/jnmt.121.262294
