UV radiation is present in sunlight constituting about 10% of the total lightoutput of the Sun.

It expresses the inability of the classical concepts "particle" or "wave" to fully describe the behaviour of quantum-scale objects.

Most of the increased exposure in the United States is due to CT scanning and nuclear imaging, which require larger radiation doses than traditional x-rays. A chest x-ray, for example, delivers 0.1 mSv, while a chest CT delivers 7 mSv (see the table) — 70 times as much.
