DANB Radiation Health and Safety Exam RHS

Ready to take DANB’s RHS exam? You can apply online right now!

DANB’s RHS exam is a component exam of both the NELDA and CDA certifications. There are no eligibility requirements for taking the RHS exam, so you can apply at any time.

We’re here for you.

DANB is extending all testing windows from 60 days to 150 days. We made this change to give you more time to schedule and take your exam. We recently learned that Pearson VUE testing centers will be closed through at least April 16. During this time, you can still apply for DANB exams and you can schedule your exams for 4/17/2020 or later.  We encourage you to apply online for faster processing. We will work with you to schedule your exam as soon as Pearson VUE notifies DANB that test centers have reopened. For more details, visit the link below.
