Neutron radiation is a form of ionising radiation consisting of free neutrons.
Neutron radiation is rarely produced by the natural decay of atomic nuclei. It is usually produced artificially with the help of neutron sources; neutron radiation is also released during nuclear fission.
When neutrons hit components in the reactor core and change their material properties so that they can become more susceptible to so-called brittle fracture, this is called neutron embrittlement.
Radioactivity is the property of unstable atomic nuclei to spontaneously transform into another nucleus without external influence. During this transformation, the atomic nucleus emits ionising radiation.
Radioactive types of atoms are called radionuclides. Compared to other atoms, they are unstable and decay after a certain time. This releases energy in the form of radiation.
The unit of measurement “sievert” (Sv) is used to indicate the effect of ionising radiation on organisms. Various dose quantities are given in sieverts, e.g. the equivalent dose or the effective dose.
After a nuclear facility (e.g. nuclear power plant, research reactor, etc.) is finally shut down, it is generally decommissioned.
The term "malicious act " is used to describe the attempt to remove radioactive materials or to cause a release of radioactive materials.
Anybody working by profession in different establishments where they may be exposed to ionising radiation needs a radiation passbook.
Underground laboratories are used to conduct experiments in the field of repository research under natural ambient conditions.
In an information notice, findings from events in domestic or foreign nuclear installations that can be applied to (other) German facilities are presented.
