How Much Radiation Does it Take to Cause Cancer?

It is a common misconception that any amount of radiation can cause cancer. However, the real risk of radiation-induced cancer is very low and a large amount of radiation is needed to cause it. This has been established by the largest human population ever exposed to high levels of ionizing radiation, the Life Span Study (LSS) cohort of Japanese atomic bomb survivors. Based on these studies, the U.

S. Food and Drug Administration (FDA) estimates that exposure to 10 mSv from an imaging test would increase the risk of death from cancer by approximately 1 chance in 2000. This is a very small risk, and it is important to understand that radiation exposure does not necessarily lead to cancer. It can be difficult to study cancer risks from imaging studies that use radiation, but it is important to remember that radiophobia is not justified.

The risk of developing cancer from radiation exposure is very low, and it is important to understand the facts before making assumptions about radiation and cancer.
