Rads per minute (rad/min)
Rads per hour (rad/h)

Conversion Formula

rad/h = rad/min × 60

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 Rads per hour

The rad per hour (rad/h) equals 0.01 Gy/h ≈ 2.78×10⁻⁶ Gy/s. Standard unit on US emergency dosimetry instruments and civil defense survey meters; Chernobyl sarcophagus contact dose rates were hundreds of rad/h; criticality accident dosimetry and NRC incident reports continue to evaluate dose rates in rad/h. 1 rad/h = 0.01 Gy/h = 10 mGy/h.
