This session outlines key methodologies used in assessing radiological safety, focusing on problem statements and driving factors behind these methodologies. It explores goals such as screening and dose calculations, highlighting dose limits and protection criteria. The development process for these methods is discussed, including technical approaches, modeled pathways, and safety factors for various media types. Additionally, the session covers assumptions regarding receptor types and geometries, the relevance of progeny RBE for alpha particles, and the status of documentation for these methodologies.

Session 1: Methods Reviews • Problem statement and driver for the methodology • Goals of the methodology (e.g., screening; dose calculation) • Dose limits or protection criteria being met • Process employed for methods development • Technical approach and derivation • assumptions pathways modeled • media types safety factors; conservatism • default parameters receptor types and geometries • progeny RBE for alpha particles • site-specific modifications use of probabilistic tools/ analysis • Status of the method and availability of documentation and calculational tools
