Convert Kilorads per hour to Grays per minute
Convert Kilorads per hour (krad/h) to Grays per minute (Gy/min) instantly and accurately.
Conversion Formula
Gy/min = krad/h × 0.1666666667
About Kilorads per hour
The kilorad per hour (krad/h) equals 10 Gy/h ≈ 2.78×10⁻³ Gy/s. Used in total ionising dose (TID) testing of electronics for space and military: satellite components are irradiated at krad(Si)/h to simulate accumulated space radiation; MIL-STD-883 and ESCC 22900 specify test dose rates in krad/h. 1 krad/h = 10 Gy/h.
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.
