Convert Millisieverts per hour to Milligrays per second
Convert Millisieverts per hour (mSv/h) to Milligrays per second (mGy/s) instantly and accurately.
Conversion Formula
mGy/s = mSv/h × 0.0002777777778
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 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.
