  Ionising Radiation
Ionising radiation includes both electromagnetic radiation – such as X-rays and gamma radiation – and particle radiation – such as alpha, beta and neutron radiation. Its main feature is that it has enough energy to ionise atoms and molecules, i. e. to generate positively and negatively charged particles from electrically neutral atoms and molecules. When going through matter – e. g. through a cell or an organism – ionising radiation gives off energy. If this energy is high enough serious radiation damages can occur. Ionising radiation is both part of nature and the result of human activities.Natural radioactive substances exist in man and in the soils and rocks of the earth´s crust. In the medical field, in research, technology and through using nuclear energy radioactive substances are used purposefully and generated artificially.

Type approval of ionising smoke detectors (ISM)
|
|
Ionising smoke detectors (ISM) are equipments that contain radioactive materials, mostly Americium-241. The radiation of the radioactive material ionizes the air located in the smoke detectors (full text in German only).
