Determining factors for radiation injury
WebThis number is known as the Quality Factor (Q). When a person is exposed to radiation, scientists can multiply the dose in rad by the quality factor for the type of radiation present and estimate a person’s biological risk in rems. Thus, risk in rem = rad X Q. The rem has been replaced by the Sv. One Sv is equal to 100 rem. WebRadiation injury to the skin (transient erythema) has been observed at absorbed doses in the skin of about 2 Gy (200 rad). More severe effects may occur following larger absorbed doses.
