About Kilorads
The kilorad (krad) equals 10 Gy. Used in radiation hardness testing of electronics for space and military applications: commercial components typically withstand 0.1-10 krad(Si); military-grade components are specified to 100-1000 krad(Si). Semiconductor device qualification standards (MIL-STD-883, ESCC 22900) quote total ionising dose in krad. 1 krad = 10 Gy.
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.
