Convert Rads per hour to Nanograys per hour

Convert Rads per hour (rad/h) to Nanograys per hour (nGy/h) instantly and accurately.

Rads per hour (rad/h)
Nanograys per hour (nGy/h)

Conversion Formula

nGy/h = rad/h × 10000000

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 Nanograys per hour

The nanogray per hour (nGy/h) equals 1e-9 Gy/h ≈ 2.78×10⁻¹³ Gy/s. Natural background cosmic-ray dose rates at sea level are 30-50 nGy/h; at aviation cruising altitude they rise to 3000-6000 nGy/h. IAEA environmental surveillance networks and national monitoring stations report ambient gamma dose rates in nGy/h. 1 nGy/h = 1e-9 Gy/h.
