About
In December 2026, the Radboudumc will start a new edition of the radiation safety training courses TMS‑VRS‑C and TMS‑VRS‑D. These courses are designed for students and staff who work with open radioactive sources in radionuclide laboratories and who require formal certification to do so safely and independently.
More informationAbout
TMS‑VRS‑D – Radiation Protection Officer, Level D
The VRS‑D course prepares participants to supervise low‑risk radionuclide laboratories and to perform standardized, low‑risk experiments with open radioactive sources.
-
Duration: 3 full days + 2 half days
-
Content: foundational radiation physics, biological effects of ionizing radiation, legislation, safe laboratory practices, contamination control, and practical skills such as radiation detection and basic decontamination.
-
Level: introductory, focusing on essential knowledge and skills.
TMS‑VRS‑C – Radiation Protection Officer, Level C
The VRS‑C course is intended for those who supervise intermediate‑risk radionuclide laboratories or perform scientific experiments involving open radioactive sources.
-
Duration: 8 full days
-
Content: the same core topics as VRS‑D, but at a more advanced level, including deeper theoretical understanding, more extensive practical training, and broader responsibilities in radiation protection.
-
Level: intermediate, aimed at laboratory staff, Biomedical Sciences students, and others who work without continuous supervision.
Course Approach and Examination
Both courses combine lectures, practical sessions, and self‑study. Participants will train essential laboratory skills such as radiation detection, contamination monitoring, and decontamination procedures. Online learning modules support the self‑study component and help prepare for the exam.
The training concludes with a written examination. Upon passing, participants receive the official Dutch diploma.
