Convert Megagrays to Megarads
Convert Megagrays (MGy) to Megarads (Mrad) instantly and accurately.
Conversion Formula
Mrad = MGy × 100
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.
About Megarads
The megarad (Mrad) equals 10⁶ rad = 10⁴ Gy. Used in radiation hardening of electronics and wire/cable insulation: cross-linked polyethylene (XLPE) cable insulation is cured at 5-20 Mrad; some legacy radiation hardness assurance (RHA) test reports for space electronics quote doses in Mrad(Si). 1 Mrad = 10⁴ Gy = 10 kGy.
