Inthe French scientist Paul Villard discovered a third neutrally charged and especially penetrating type of radiation from radium, and after he described it, Rutherford realized it must be yet a third type of radiation, which in Rutherford named gamma rays. Hence ingesting, inhaling or absorbing radioactive chemicals capable of emitting alpha or beta particles and thereby placing them inside delicate body parts such as the lungs, heart, brain or kidneys, always poses serious threats to human health. When this happens, they emit particles or rays, including: The thicker the substance, the more the radiation is absorbed. Similarly, x-rays are typically used to provide static images of body parts such as teeth and bonesand are also used in industry to find defects in welds.

In some cases, it may lead to secondary emission of visible light upon its interaction with matter, as in the case of Cherenkov radiation and radio-luminescence.
Nuclear radiation, what you need to know.
Nuclear Radiation There are three primary radiation types associated with radioactivity. Gamma radiation, however, is composed of photons, which have neither mass nor electric charge and, as a result, penetrates much further through matter than either alpha or beta radiation.
