Radiation Safety

Quick fact

The average person receives about 3 millisieverts (mSv) of natural background radiation per year. A single chest X-ray gives about 0.1 mSv, while a CT scan can deliver up to 10 mSv. The principle of radiation safety aims to keep all exposures as low as reasonably achievable.

Why this is interesting

We use X-rays to see inside our bodies, but did you know that overexposure to radiation can cause immediate and long-term health effects? How do professionals ensure that the benefits outweigh the risks?
