Rad Lab: Interactive RHS Study Scenarios

This interactive exam prep game provides the foundational knowledge and practical skills to safely expose dental radiographs. Whether preparing for the Dental Assisting National Board (DANB) Radiation Health and Safety (RHS) exam or training on the job, you’ll learn through engaging activities, gamified challenges, and real-world scenarios. Earn points and receive feedback as you go to help you fine-tune your study plan. As you progress through the levels, you’ll explore the purpose of dental imaging, radiation physics and biology, radiation safety, infection control, head and oral anatomy, radiographic equipment, radiographic techniques, and common imaging errors. By the end, you’ll be better prepared to confidently produce diagnostic dental images safely and effectively with three final scenarios that tie everything you learned together.

Questions are not from the actual RHS exam and successfully completing the Rad Lab does not guarantee you will pass the RHS exam. Although you can review the Rad Lab as often as you'd like within your access period, you cannot go back and change your answers.
