DANB Radiation Health and Safety (RHS) Exam 2025 – 400 Free Practice Questions to Pass the Test

The key to minimizing excessive radiation exposure in a dental setting is adherence to the principles of radiation safety, which encompass proper shielding and technique. This practice involves employing protective barriers such as lead aprons and thyroid collars for patients, as well as utilizing properly designed imaging equipment that limits unnecessary radiation dispersal.

Additionally, following proper technique — such as adjusting exposure times and settings according to the specific imaging needs and patient requirements — helps to avoid overexposure. These procedural safeguards ensure that both patients and staff are protected from excessive radiation while still obtaining the necessary diagnostic information.

In contrast, simply increasing the distance from the radiation source may help in reducing exposure to some extent but is not as comprehensive as implementing all aspects of radiation safety principles. Limiting the number of patients seen does not directly address the issue of exposure per individual patient. Using lower quality imaging equipment could lead to higher radiation exposure as it might require longer exposure times or result in poor-quality images requiring additional retakes. Therefore, the best approach is a carefully structured and comprehensive application of radiation safety protocols.
