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

Maintaining a safe distance from radiation sources is a fundamental principle of radiation protection. This concept is grounded in the Inverse Square Law, which states that the intensity of radiation decreases with distance. By increasing the distance from a radiation source, the exposure risk is significantly reduced, effectively minimizing potential harm to individuals.

In practical terms, staying farther away from sources of radiation whether they are medical devices, radioactive materials, or industrial sources directly contributes to safeguarding health and safety. Implementing this principle allows healthcare professionals, patients, and others who work in environments with radiation exposure to mitigate the associated risks effectively.

Other principles of radiation safety, while important, do not align with this specific tenet of maintaining distance for protection.
