← Physics domain / RISC — Radioisotope Safety
Radioisotope Safety (RISC)
Regulatory framework (NRC, Agreement States, RSO/RSC), isotope properties, shielding choices, spill response, post-therapy patient release. The "NIS-lite" of the physics exam — memorize the numbers and the procedures.
Categories Click to drill this category
Regulatory →NRC, Agreement States, RSO, RSC, medical events.
Isotopes →Half-lives, decay modes, photon energies for diagnostic and therapy.
Handling →Shielding choices, syringe shields, extremity dose.
Spills →Minor vs major, CANS response sequence, decon.
Patient release →I-131 criteria, written instructions, household precautions.
