Only a very small proportion of the ions and biomolecules in organisms are radioactive. However, many of their atoms can be converted into artificial emitters (isotopes), whose radioactive radiation can be utilised for many scientific questions. The isotopes decay into other, mostly non-radiating atoms. This decay can take seconds, days, years or millennia. Due to the radiation released, special protective measures are therefore required to protect people and the environment. This may also be necessary when dealing with X-ray and interference emitters.

At the University of Oldenburg, we essentially have four areas in which employees and students can come into contact with ionising radiation:

1. Activities in the isotope laboratory (handling open, radioactive substances)
2. Handling X-ray and interference emitters at the University of Oldenburg
3. Handling sealed sources at the University of Oldenburg
4. Radiation protection for employees and students in human medicine, medical physics and acoustics, healthcare research and psychology who work in clinics, teaching hospitals and doctors' surgeries ("employment in external facilities")

The following persons are the contact persons for activities in the isotope laboratory (1.) and handling X-ray, interference and sealed sources (2.,3.) at the University of Oldenburg:
