About Kilograys

The kilogray (kGy) equals 10³ Gy and is the standard unit for radiation processing. Food irradiation: 1-10 kGy for insect disinfestation and sprout inhibition; medical device sterilisation standard dose is 25 kGy (ISO 11137); polymer crosslinking and cable insulation curing use 50-200 kGy. 1 kGy = 10³ Gy = 10⁵ rad.

About Grays

The gray (Gy) is the SI coherent unit of absorbed radiation dose, defined as 1 joule of energy deposited per kilogram of matter. Named after Harold Gray (British radiobiologist, 1905-1965). Used globally in radiotherapy: curative tumour doses 40-80 Gy fractionated; total body irradiation before bone marrow transplant 12-14 Gy. 1 Gy = 1 J/kg = 100 rad.
