Convert Microsieverts per hour to Milligrays per second
Convert Microsieverts per hour (µSv/h) to Milligrays per second (mGy/s) instantly and accurately.
Conversion Formula
mGy/s = µSv/h × 2.777777778e-7
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.
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.
