In recent months, several media reports have focussed on radiation risks to patients undergoing CT and radiation treatment and have reported cases of over-exposures both in CT and radiotherapy.

Professional societies (AAPM, IOMP, ASTRO) and regulatory bodies (such as FDA) have shown concern.

The IAEA has a number of actions that contribute to achieving higher levels of safety and reducing the probability of radiation events.
