Who administers the DANB Radiation Health and Safety (RHS®) and Infection Control (ICE®) Exams?

Dental Assisting National Board, Inc. (DANB) — exam delivered by Pearson VUE. DANB states its exams are delivered by Pearson VUE. RHS and ICE are two separate DANB exams: each can be taken on its own, in person at a Pearson VUE test center or through online remote proctoring, or the two can be taken together as the combined RHS/ICE exam, for which DANB lists test-center delivery only.

How many questions are on the DANB Radiation Health and Safety (RHS®) and Infection Control (ICE®) Exams?

75 questions. Per exam: DANB lists 75 multiple-choice questions for RHS and 75 for ICE, so a candidate who needs both answers 150 in total — the figure DANB lists for the combined RHS/ICE exam. DANB states a small number of unscored pretest questions may appear on each exam; it does not say how many, so no scored count is given here.

How long is the DANB Radiation Health and Safety (RHS®) and Infection Control (ICE®) Exams?

60 minutes. Per exam: 60 minutes for RHS and 60 minutes for ICE. Taken together as the combined RHS/ICE exam, DANB lists 120 minutes.

What is the passing score for the DANB Radiation Health and Safety (RHS®) and Infection Control (ICE®) Exams?

Scaled score of 400 on a 100–900 scale. The same rule for each exam, stated in both the RHS and the ICE outline: a scaled score of 400 or higher, on a scale of 100 to 900. DANB is explicit that the scaled score is neither a number correct nor a percent correct: the exams are computer-adaptive and scored on the difficulty of the questions answered correctly, and DANB says the average candidate answers around half the questions correctly. PrepPass states no percentage for this exam.

How much does the DANB Radiation Health and Safety (RHS®) and Infection Control (ICE®) Exams cost?

$270 — RHS exam (taken on its own) (DANB, per attempt); $270 — ICE exam (taken on its own) (DANB, per attempt); $375 — Combined RHS/ICE exam (both in one appointment) (DANB, per attempt). DANB's Candidate Handbook states there is no limit on retakes of a failed exam, but each retake means reapplying and paying the full exam fee. Refunds are reduced by DANB's processing and cancellation fees, which are listed in the handbook. Whatever a state charges for its own dental-assisting permit or registration is set by that state, not by DANB.

What languages is the DANB Radiation Health and Safety (RHS®) and Infection Control (ICE®) Exams offered in?

English · Spanish. DANB's RHS, ICE and combined RHS/ICE pages each say: “This exam is also offered in Spanish.” DANB separately lists Oregon state exams in Spanish and Vietnamese; those are Oregon's own exams, not RHS or ICE.

Does the Dental Assisting (Radiation & Infection Control) cram sheet come as a PDF?

Yes — Dental Assisting — Cram Sheet (2026) downloads as PDF, 27 pages. The download link is emailed the moment payment clears and does not expire.

What is the difference between the Dental Assisting (Radiation & Infection Control) study guide and the cram sheet?

The study guide ($14.99) teaches the material chapter by chapter and is meant to be read over weeks. The cram sheet ($9.99, 27 pages) drops the teaching and keeps the figures: every number on the exam grouped by value so the confusable ones sit together, each reference page paired with a recall page that blanks the answers, and four routes by days left — 14, 7, 3, or tonight. They are separate purchases; neither replaces the other.

Is this the official Dental Assisting (Radiation & Infection Control) cram sheet?

No. This is an independent cram sheet and is not affiliated with or endorsed by the exam's awarding body. It is written from CDC dental infection-control guidelines / OSHA 1910.1030 & 1910.1200 / NCRP / FDA-ADA. Always confirm current requirements with the body that issues your licence.
