  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.

Do the forest fires in Russia cause enhanced radioactivity in the atmosphere?
|
|
|
Fires in the Chernobyl area can have radiological effects on the immediately surrounding area if people inhale the radioactive particles in the air. However, the fires do not have any radiological consequence for the rest of Europe and Germany since the dispersion of the radioactive substances is regionally limited. This has been known from former fires in the area. There was one case where traces of radioactive substances were transported to Germany whose concentration was harmless under radiation protection aspects, however.

X-ray scanner for the screening of cabin baggage at airports
|
|
In Germany, the use of X-ray scanner for the screening of cabin baggage at airports is justified under the legal basis of the binding Regulation 2320/2002 of the European Parliament concerning civil aviation security. The devices have to undergo a primary inspection as well as regular control checks in order to ensure that in the vicinity of the devices, where employees or other persons may linger, the dose limit for a single person of the general public (including pregnant women and children) is not exceeded, even during a permanent stay.
