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 Grays per second

The gray per second (Gy/s) is the SI coherent unit of absorbed dose rate, equal to 1 joule per kilogram per second, dimensionally equivalent to W/kg or m²/s³. Used in HDR brachytherapy source strength, FLASH radiotherapy research (>40 Gy/s for normal tissue sparing), and particle accelerator beam-loss dosimetry. 1 Gy/s = 60 Gy/min = 3600 Gy/h = 100 rad/s.
