Convert Milligrays to Nanograys
Convert Milligrays (mGy) to Nanograys (nGy) instantly and accurately.
Conversion Formula
nGy = mGy × 1000000
About Milligrays
The milligray (mGy) equals 10⁻³ Gy and is the standard unit for diagnostic radiology patient doses. CT head scan ~20-60 mGy; abdominal CT ~10-30 mGy; mammography mean glandular dose ~1-3 mGy. IAEA and EU medical exposure directives set diagnostic reference levels in mGy. 1 mGy = 10⁻³ Gy = 0.1 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.
