Primary texts often used in such courses:

Published amid growing adoption of targeted radiopharmaceutical therapies, MIRD Pamphlet 24 responded to urgent needs: mird237 2021

But even then, that's pamphlet 24, not 237. The confusion might be due to a miscalculation or incorrect number. Given that, perhaps the user meant MIRD Pamphlet 24 from 2021, which provides guidelines on dosimetry calculations relevant to radionuclide therapy.

[ Administered Activity ] │ ▼ [ Cumulative Activity (Ã) ] ──► (How long it stays in the Source Organ) │ ▼ [ Multiply by S-Value ] ──► (Physical decay + Phantom geometry data) │ ▼ [ Absorbed Target Dose (D) ] ──► (Final energy deposited in Target Organ) Given that, perhaps the user meant MIRD Pamphlet

The framework is not static. As of late 2025, the committee has announced work on:
