Convert Grays per minute to Rads per second
Convert Grays per minute (Gy/min) to Rads per second (rad/s) instantly and accurately.
Conversion Formula
rad/s = Gy/min × 1.666666667
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.
About Rads per second
The rad per second (rad/s) equals 0.01 Gy/s. Used in US radiation therapy physics and pulsed accelerator dosimetry: FLASH radiotherapy (FLASH-RT) research defines ultra-high dose rate as >40 Gy/s = 4000 rad/s; linac prompt radiation dose rates during pulsed operation are characterised in rad/s; nuclear detonation prompt gamma fields are described in rad/s. 1 rad/s = 0.01 Gy/s = 1 cGy/s.
