The Board’s goal is to be proactive about maintaining the value and validity of the Certified Medical Dosimetrist credential through both the examination and maintenance of the Certified Medical Dosimetrist registry.  As a part of its duty, the MDCB must make every effort to ensure professionals who are credentialed as Certified Medical Dosimetrists are adhering to the policies and procedures and the Code of Ethics as set forth by the MDCB.

If you have questions or do not plan on renewing your credential, please contact the MDCB office by e-mail at
