Megagrays (MGy)
Micrograys (µGy)

Conversion Formula

µGy = MGy × 1000000000000

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 Micrograys

The microgray (µGy) equals 10⁻⁶ Gy. Typical organ doses from diagnostic X-ray procedures: chest X-ray ~0.01-0.1 µGy; mammography mean glandular dose ~1-3 mGy (i.e. 1000-3000 µGy); dental bitewing ~1-5 µGy. IAEA Safety Reports quote entrance surface doses in µGy for patient dose surveys. 1 µGy = 10⁻⁶ Gy.
