Convert Millirads per hour to Microsieverts per hour
Convert Millirads per hour (mrad/h) to Microsieverts per hour (µSv/h) instantly and accurately.
Conversion Formula
µSv/h = mrad/h × 10
About Millirads per hour
The millirad per hour (mrad/h) equals 1e-5 Gy/h = 10 µGy/h. Legacy US radiation protection unit used by area monitors and Geiger counters calibrated before SI adoption; EPA environmental surveillance stations report in mrad/h alongside µGy/h; NRC licence boundary dose-rate surveys often cite mrad/h. 1 mrad/h = 1e-5 Gy/h = 10 µGy/h.
About Microsieverts per hour
The microsievert per hour (µSv/h) equals 1e-6 Sv/h = 1e-6 Gy/h for photon radiation (wR = 1). The universal display unit of personal electronic dosimeters and ambient dose-equivalent rate monitors: typical outdoor background 0.08-0.3 µSv/h; IAEA precautionary action level is 100 µSv/h; occupational continuous limit ≈2.3 µSv/h. 1 µSv/h = 1 µGy/h for photons.
