The risk of radiation-induced cancer from a single fluoroscopic exam is what percent per Sv?

The risk of radiation-induced cancer from a single fluoroscopic exam is estimated to be about 5% per Sv (sievert) of radiation exposure. This percentage reflects the understanding that for every sievert of radiation absorbed by the body, there is an approximate 5% increased lifetime risk of developing cancer. This statistic stems from extensive epidemiological studies and risk assessments, particularly among populations exposed to higher levels of radiation, such as atomic bomb survivors.

The specifics of the risk percentage can be influenced by factors such as age, sex, and underlying health conditions, but the 5% per Sv figure provides a general guideline for the risk associated with fluoroscopy. Consequently, health professionals use this information to inform patients about the potential risks versus the diagnostic benefits of these imaging procedures. Understanding radiation risk is crucial for medical practitioners when making decisions regarding the use of fluoroscopy in patient care.
