Gamma-ray dose constants
Gamma-ray dose constants for radionuclides
Effective dose (Peplow 2020 / ICRP-116 AP), µSv·m²/(MBq·h) at 1 m. Values are for the bare nuclide without daughter ingrowth — see Cs-137 below. For positron emitters (marked β⁺) the table excludes the 511 keV annihilation photons, so the practical Γ of a real source is higher — use the dose-rate calculator, whose constants include them.
