Refresher course TMS-VRS D

– Radioactive materials in dispersible form –

-Click here [1] for the Dutch version-


A refresher course is offered for employees of the Randwyck institutions who work in a setting that requires an education in the field of radiation protection at the level of TMS-VRS D. Participation in this program is obligatory for all employees who work autonomously with dispersible radioactive materials. This program ensures both compliance with legal requirements as well as maintaining a safe work environment.



Do you work or plan to work with (dispersible) radioactive materials within the Randwyck institutions but have not been contacted about participating in the program? Please register for this program by sending us an email [9]


Legal requirements

It is a legal obligation for employers to inform their employees about the risks that come with exposure to ionising radiation. Within the institutions of the complex license , this obligation is met by enrolling employees who work with radioactive sources in dispersible form (VRS) in the course  TMS-VRS D (Radiation Protection Officer– dispersible radioactive materials level D).


Employers also need to ensure that their employees’ knowledge on the subject stays up to date. For this purpose, a refresher course has been installed for those that use radioactive sources in spreadable form. Participation in this program is obligatory for performing experiments with radioactive sources autonomously as well as being granted entrance to the department of Radio Nuclides Laboratories (RNL).


Educational purposes

For the refresher course on radiation protection, the following educational purposes have been determined:


Program 2018-2019

A second edition of the refresher course radiation protection is being planned for the period 2018-2019. The official language during the program is English; this may be deviated from during practical assignments if the composition of the group justifies this: in that case, the assignment may be presented in Dutch.


For 2018, the program is as follows:

For 2020/2021 there will be a program that compares to the 2018/2019 program.


Minimum requirements for participation

For the 2018-2019 program, it is expected that one participates in the practical assignment, attends 3 theoretical lectures and 2 informational lectures. This represents a time investment of 12 hours over a period of two years.


Meeting the minimum requirement for participation is a condition for maintaining access to the RNL department and/or autonomously working with radioactive sources in dispersible form .



To participate in any component of the program, you must register beforehand. This can be done through our e-mail account [9].


Attention please! For both the practical assignment and the theoretical lecture/tutorial ‘Risk analysis of frequently used techniques’ there is a limited number of participants per session.

Per practical assignment session, 4 participants can register.  It should be noted that there is room for 40 participants in 2018 and an additional 40 spots in 2019. The maximum number of participant for the turotial is 16 per date (these 16 will be divided in 2 groups of 8 participants each).


For both the practical assignment and the tutorial the rules is that registration takes place on a first come, first serve basis.


What to do if the minimum requirements for participation are not met

Employees who have not met or threaten not to met the minimum requirements for participation in the 2018-2019 edition of the refresher course, but want to keep their access to the RNL department and/or want to work autonomously with radioactive sources in dispersible form, must participate in the remaining part of the refresher course in 2019 ánd need to take an (multiple-choice) examination of the regular TMS-VRS D course. The result of this exam should be positive (>60%). Only in this way the level of knowledge about radiation protection is demonstrable to the required TMS-VRS D. Employees in question are personally informed about the components they are short of.
