Convert Millirads to Megagrays
Convert Millirads (mrad) to Megagrays (MGy) instantly and accurately.
Conversion Formula
MGy = mrad × 1.000000000e-11
About Millirads
The millirad (mrad) equals 10⁻³ rad = 10⁻⁵ Gy = 10 µGy. Older US health physics reports and NRC licence conditions quote occupational extremity doses in mrad; some film badge dosimetry reports still use mrad for historical continuity. 1 mrad = 10⁻³ rad = 10⁻⁵ Gy = 10 µGy.
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.
