The online training course “Radiation Protection” is aimed at persons who are in radiation protection areas due to their occupational activity, e. g. during X-ray examinations. The course explains the basics of how X-rays are generated, possible hazards from X-rays, and safety and protective measures. Additionally, employees in exposed areas also receive a great deal of information on radiation protection areas and dose minimization, working methods, radiation protection law and radiation protection instructions. The instruction module was developed in a cooperation between ” Strahlenschutz-Instruktion, Edgar Pahlke ” and SZENARIS GmbH.
