About Millirads
The millirad (mrad) equals 10⁻³ rad = 10⁻⁵ Gy = 10 µGy. Older US health physics reports and NRC licence conditions quote occupational extremity doses in mrad; some film badge dosimetry reports still use mrad for historical continuity. 1 mrad = 10⁻³ rad = 10⁻⁵ Gy = 10 µGy.
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.
