Convert Grays per hour to Nanograys per hour
Convert Grays per hour (Gy/h) to Nanograys per hour (nGy/h) instantly and accurately.
Conversion Formula
nGy/h = Gy/h × 1000000000
About Grays per hour
The gray per hour (Gy/h) equals 1/3600 Gy/s ≈ 2.78×10⁻⁴ Gy/s. Used in radiation processing and source strength reporting: ¹³⁷Cs irradiator calibrations are expressed in Gy/h at a reference distance; IAEA food irradiation standards cite Gy/h for conveyor output; radiobiological experiments for cancer cell survival curves use Gy/h. 1 Gy/h = 100 rad/h = 1000 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.
