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 Kilograys per second

The kilogray per second (kGy/s) equals 1e3 Gy/s. Encountered in FLASH radiotherapy research at ultra-high dose rates and in high-power industrial electron accelerators for polymer crosslinking and cable curing at pulse-peak intensities; free-electron laser (FEL) and wakefield accelerator beam-loss dosimetry reports cite kGy/s. 1 kGy/s = 1e3 Gy/s = 3.6 MGy/h.
