What device is used to shield against unnecessary radiation exposure for patients?

Lead aprons are the primary device used to shield patients from unnecessary radiation exposure during imaging procedures, particularly in radiology and fluoroscopy. They are made of lead or lead-equivalent materials that effectively attenuate the radiation, preventing it from reaching critical areas of the body. This is crucial in protecting sensitive organs, such as the reproductive organs, thyroid, and eyes, especially during prolonged exposure to X-rays.

The effectiveness of lead aprons in minimizing scatter radiation is widely recognized in clinical practice. Their use is standard protocol in many healthcare settings for both patients and healthcare providers during various radiological procedures. Other protective devices do exist, but they serve different purposes or are specific to different contexts.

For instance, dental shields are specifically designed for dental radiography, while safety helmets and X-ray goggles are not applicable to general radiation protection in other medical imaging scenarios. Lead aprons, due to their widespread application and proven efficacy in shielding against X-ray radiation, are the most appropriate choice for this context.
