Dose rate constants from Cornejo et al. (2006). Energy threshold δ = 20 keV, yield ≥ 0.01%. Units: Γ^K-air in µGy·h⁻¹·GBq⁻¹·m²; Γ^H*(10) and Γ^H'(0.07) in µSv·h⁻¹·GBq⁻¹·m².

Reference & Data Notes

Cornejo et al. — primary source for Γ^H*(10) values for 32 nuclides.
Γ^H'(0.07) values in parentheses from Cornejo et al. apply when all photon energies < 300 keV and H'(0.07) > H*(10). Used for extremity dose estimation.
Ga-68 and Y-90 constants calculated using ICRU 57 / ICRP 74 methodology (same as Cornejo et al.).
