About Millisieverts per hour

The millisievert per hour (mSv/h) equals 1e-3 Sv/h = 1e-3 Gy/h for photon radiation. Standard field survey unit in radiation protection: nuclear power plant boundary limits are stated in mSv/h; NRC and IAEA emergency alert levels for the public begin at 1 mSv/h; portable radiation survey instruments have a dedicated mSv/h range. 1 mSv/h = 1 mGy/h for photons.

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.
