Convert Grays per second to Rads per hour
Convert Grays per second (Gy/s) to Rads per hour (rad/h) instantly and accurately.
Conversion Formula
rad/h = Gy/s × 360000
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.
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.
