Convert Rads per minute to Microsieverts per hour
Convert Rads per minute (rad/min) to Microsieverts per hour (µSv/h) instantly and accurately.
Conversion Formula
µSv/h = rad/min × 600000
About Rads per minute
The rad per minute (rad/min) equals 0.01 Gy/min ≈ 1.67×10⁻⁴ Gy/s. Historically the primary US radiation therapy output unit: cobalt-60 and early linac machines from the 1960s-1980s are documented in rad/min at isocentre; radiation processing conveyor throughput calculations and legacy NIST linac calibrations use rad/min. 1 rad/min = 0.01 Gy/min = 1 cGy/min.
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.
