Ionizing radiation is not detectable by human senses, so radiation detection instruments such as Geiger counters must be used to indicate its presence and measure it. However, high intensities can cause emission of visible light upon interaction with matter, such as in Cherenkov radiation and radioluminescence.

The Ionizing and Penetration Power of Radiation The increased use of radioisotopes has led to increased concerns over the effects of these materials on biological systems (such as humans). When this radiation encounters living cells, it can cause heating, break chemical bonds, or ionize molecules.

Ionizing radiation takes a few forms: Alpha, beta, and neutron particles, and gamma and X-rays. All types are caused by unstable atoms, which have either an excess of energy or mass (or both). In order to reach a stable state, they must release that extra energy or mass in the form of radiation.
