About Ergs per gram

The erg per gram (erg/g) equals exactly 10⁻⁴ Gy and is the CGS-Gaussian unit of absorbed dose. Because 1 rad was originally defined as 100 erg/g, this unit is directly linked to the historical radiation system. Still found in older nuclear physics and health physics texts predating SI adoption. 1 erg/g = 10⁻⁴ Gy = 0.1 mGy.

About Megagrays

The megagray (MGy) equals 10⁶ Gy. Doses in the MGy range destroy virtually all molecular structures. Radiation chemistry of water reaches radical recombination equilibrium above 1 MGy; neutron-irradiated reactor pressure vessel steels accumulate fast-neutron damage equivalent to 0.01-1 MGy over a 40-year lifetime. 1 MGy = 10⁶ Gy = 10⁸ rad.
