For decades, we have been told that exposure to radiation is dangerous. In high doses it is certainly lethal and chronic exposure is linked to the development of cancer. But, what if a short-term controlled exposure to a low dose of radiation were good for our health.

According to a new study, patients are receiving estimated doses of radiation from medical diagnostic imaging studies, such as CT (or “CAT”) scans, that may be detrimental to their long term health, putting them at an increased risk of developing cancer. To date, emergency physicians have not been made aware of the cumulative amount of radiation that their patients receive.
