Convert Megagrays to Nanograys
Convert Megagrays (MGy) to Nanograys (nGy) instantly and accurately.
Conversion Formula
nGy = MGy × 1000000000000000
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 Nanograys
The nanogray (nGy) equals 10⁻⁹ Gy. Background cosmic-ray dose rate at sea level is ~0.03-0.05 nGy/s; environmental low-dose-rate studies of DNA damage in cultured cells use nGy doses delivered over days; regulatory derived investigation levels for some radionuclides in food correspond to organ doses in nGy. 1 nGy = 10⁻⁹ Gy = 10⁻³ µGy.
