What protective measures should EMTs use during radiologic events?

• A. Rely on standard precautions only.
• B. Use time, distance, and shielding to reduce exposure.
• C. Ignore shielding if there are many patients.
• D. Only wear gloves and a mask.

Answer: (B)

Time, distance, and shielding are the cornerstone of protection during radiologic events. Ionizing radiation exposure increases with time spent near the source, so every moment you can reduce your close, active time near the source lowers your dose. Plan assessments and patient care to be efficient, and rotate personnel to limit any one responder’s time in a high-exposure area. The radiation you receive also drops off dramatically as you increase distance from the source, so moving back or positioning barriers between you and the source is one of the most effective protections you have. Even small increases in space can translate into large reductions in dose because the intensity falls off quickly with distance. Shielding adds a physical barrier between you and the radiation; using barriers or shielding materials whenever feasible, and wearing available protective equipment, further reduces exposure. This approach aligns with the principle of keeping exposure as low as reasonably achievable (ALARA), which is why it’s the preferred method over relying solely on standard precautions, ignoring shielding during a busy scene, or using only basic gloves and a mask. In radiologic incidents, maintain monitoring with dosimeters to track exposure and adjust you actions to keep doses as low as possible while still delivering necessary patient care.
