Convert Microrads to Milligrays
Convert Microrads (µrad) to Milligrays (mGy) instantly and accurately.
Conversion Formula
mGy = µrad × 1.000000000e-5
About Microrads
The microrad (µrad) equals 10⁻⁶ rad = 10⁻⁸ Gy. Used in legacy US radiological instrumentation calibration documentation for very low-level survey instrument thresholds; some older NRC and EPA radiation protection records quote environmental dose rates in µrad/h when modern instruments report nGy/h. 1 µrad = 10⁻⁸ Gy = 10⁻² µGy.
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.
