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 Rads per hour

The rad per hour (rad/h) equals 0.01 Gy/h ≈ 2.78×10⁻⁶ Gy/s. Standard unit on US emergency dosimetry instruments and civil defense survey meters; Chernobyl sarcophagus contact dose rates were hundreds of rad/h; criticality accident dosimetry and NRC incident reports continue to evaluate dose rates in rad/h. 1 rad/h = 0.01 Gy/h = 10 mGy/h.
