None of the above The Linear Non-Threshold (LNT) Model for risk assessment in humans exposed to radiation is very controversial and many organizations now agree it should not be used to estimate/calculate health risk in humans exposed to low doses of radiation like diagnostic CT scans.

A. 10 mGy B. 2 Gy C. 0.5 Gy D. 100 mGy If human get exposed to a large whole body dose of radiation like 1 Gy, the risk of developing cancer on average is increased above the high spontaneous rate by about how much? A 100% everyone will get cancer B 10% of people will develop radiation-induced cancer C. Cancer risk could increase in some people by a small amount 4-5% D. No one will be impacted by this dose
