RHS Radiation Safety Practice Test 2025 – 400 Free Practice Questions to Pass the Exam

The formula for calculating the maximum accumulated dose for a dental assistant is derived from regulatory guidelines and provides a method to ensure that occupational radiation exposure remains within safe limits. According to the established guidelines, the formula is based on the age of the individual in years, which reflects the cumulative effect of radiation exposure over a lifetime.

In this case, the correct formula is determined by subtracting 18 from the individual’s age and then multiplying that result by 5 rems per year. This calculation recognizes that individuals under the age of 18 should not be exposed to any significant amount of radiation as they are still in critical development stages. The use of 5 rems per year is a standard assessment for occupational exposure limits, contributing to safety protocols in environments where radiation is present.

Using this formula, healthcare providers can monitor radiation exposure safely, ensuring that the total accumulated dose does not exceed recommended limits, thus protecting the health and safety of dental assistants working in environments where they may encounter radiation from x-ray equipment or other sources.
