In the upper atmosphere, ozone gas helps shield us from damaging ultraviolet rays, but near ground level ozone is an irritant that can worsen asthma and decrease lung function. While most indoor ozone ...

Written by Prof. Renald Blundell and Dr Jean Claude Grech Ionizing radiation is a form of energy released by atoms in the form of electromagnetic waves such as gamma, x-rays or particles such as ...

When electromagnetic radiation is ionizing, it breaks the atomic bond and creates ions, which are atoms and molecules with fewer electrons or a greater number of electrons than they normally have.

WASHINGTON -- A preponderance of scientific evidence shows that even low doses of ionizing radiation, such as gamma rays and X-rays, are likely to pose some risk of adverse health effects, says a new ...

Ionizing radiation is a type of particle radiation in which an individual particle (for example, a photon, electron, or helium nucleus) carries enough energy to ionize an atom or molecule (that is, to ...

Researchers in Britain say they have discovered how ionizing radiation — such as gamma rays or X-rays used in nuclear medicine — leaves behind a molecular fingerprint in human cancers. It's already ...

The risk of cancer among physicians and other persons exposed to ionizing radiation in the workplace has been a subject of study since the 1940s, when increased mortality from leukemia was reported ...
