Convert Rads per hour to Milligrays per second
Convert Rads per hour (rad/h) to Milligrays per second (mGy/s) instantly and accurately.
Conversion Formula
mGy/s = rad/h × 0.002777777778
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.
About Milligrays per second
The milligray per second (mGy/s) equals 1e-3 Gy/s. Used in high-dose-rate applications: medical linac output in IMRT mode is 1-5 mGy/s at isocentre; electron beam processing conveyors deliver 1-10 mGy/s; real-time diode dosimeters in linac vaults measure instantaneous dose rate in mGy/s during beam-on periods. 1 mGy/s = 0.1 rad/s = 3.6 Gy/h.
