Radiopharmacist's Notes · TFIA-2 Air Sampler

Notes for the radiopharmacist running high-volume air sampling.

Each post covers one aspect of running the TFIA-2 sampling chain — eight-step sample-run SOP, dual-cartridge cross-check arithmetic, downstream counter-geometry handling, and the release-record entry the AERB inspector reads.
