About These Units
Kilogray (kGy)
A kilogray (kGy) equals 1,000 grays. Used for industrial irradiation: food preservation 1-10 kGy, medical device sterilization 25-50 kGy, cross-linking polymers 50-200 kGy. Far above any biological survivability.
Roentgen (R)
The roentgen (R) measures ionization produced by X-rays or gamma rays in air. One roentgen produces 2.58×10⁻⁴ C/kg of ionization. Approximately: 1 R ≈ 8.77 mGy or 0.877 rad in soft tissue. Named after Wilhelm Röntgen, discoverer of X-rays.
