Verification of Completion

Verification of completion of radiation safety is to be retrieved from the provider who taught the course if taken within the last 5 years.

If the course was taken longer than 5 years ago, you can request a new certificate from COMDA in writing. IF COMDA has a record of your course completion, you will be required to pay a fee of $25 for a replacement certificate.

If COMDA does NOT have a record of your course completion, you will need to retake the course.

If you need to retake the course, please see the list of approved courses.
