2.2 Procedures involving ionising radiation include: Diagnostic X-rays, CT scans or DXA scans Radiotherapy (including brachytherapy and therapy using unsealed sources) Radionuclide imaging (including diagnostic imaging and in vitro measurements).
Ionizing radiation is invisible and not directly detectable by human senses, so radiation detection instruments such as Geiger counters are required. However, ionizing radiation may lead to secondary emission of visible light upon interaction with matter, such as in Cherenkov radiation and radioluminescence.osmic rays and the decay of radioactive isotopes are the primary sources of natural ionizing radiation on Earth referred to as background radiation. In space, natural thermal radiation emissions from matter at extremely high temperatures (e.g. plasma discharge or the corona of the Sun) may be ionizing.
