RHS Exam Prep

Welcome to RHS® Exam Prep

Your Strategic Path to DANB® Certification

The Coy Academy Advantage

The Radiation Health and Safety (RHS®) exam is a challenging hurdle for many dental assistants. At Coy Academy, we don’t just give you facts to memorize; we provide the clinical context you need to understand why these protocols exist. This course is specifically engineered to align with the current DANB® exam blueprints.

What to Expect

🎯 High-Yield Content

We focus on the 20% of material that accounts for 80% of the exam questions—physics, biology, and safety.

🛡️ ALARA Focused

Safety is the largest portion of the RHS® exam. You will master patient and operator protection protocols.

Exam Breakdown

This course is divided into units that mirror the official exam categories. By the end of this prep, you will be proficient in:

Exam Category Our Focus
Radiation Safety Patient/Operator protection and Dose Limits.
Exposure & Evaluation Technique, mounting, and identifying anatomy.
Physics & Biology Ionization, x-ray production, and tissue effects.

💡 Success Strategy

  • Don’t skip the “Exam Alerts”: These red boxes throughout the course highlight actual recurring test concepts.
  • Check the Resources: Use the Student Toolkit for cheat sheets and official links.
  • Retake Quizzes: Our practice quizzes are designed to build muscle memory for technical terms.
