Conversion Formula

mSv/h = rad/h × 10

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.

About Millisieverts per hour

The millisievert per hour (mSv/h) equals 1e-3 Sv/h = 1e-3 Gy/h for photon radiation. Standard field survey unit in radiation protection: nuclear power plant boundary limits are stated in mSv/h; NRC and IAEA emergency alert levels for the public begin at 1 mSv/h; portable radiation survey instruments have a dedicated mSv/h range. 1 mSv/h = 1 mGy/h for photons.
