Convert Microsieverts per hour to Grays per minute
Convert Microsieverts per hour (µSv/h) to Grays per minute (Gy/min) instantly and accurately.
Conversion Formula
Gy/min = µSv/h × 1.666666667e-8
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 Grays per minute
The gray per minute (Gy/min) is the primary clinical radiotherapy machine output unit. Standard linac dose rates are 1-6 Gy/min at isocentre; stereotactic body radiotherapy (SBRT) uses up to 10 Gy/min; ¹⁹²Ir HDR brachytherapy sources are characterised in Gy/min at 1 cm reference distance. 1 Gy/min = 100 rad/min ≈ 1.67×10⁻² Gy/s.
