Types of Radiation Shielding Materials

Types of Radiation Shielding Materials

Radiation shielding materials are used in a variety of radiologic applications. Using radiation in diagnosing and treating patients has significantly advanced the field of medicine and saved or extended countless lives. Radiation, however, comes with risks. Those who use radiation must be adequately trained in radiation safety, radiation physics, the biologic effects of radiation and injury prevention to ensure patient safety. Lead shielding is often used in a variety of applications including diagnostic imaging, radiation therapy, and nuclear and industrial shielding.

Lead Electrolytic Shielding

Lead is a soft, malleable and corrosion-resistant material. The high density of lead makes it a useful shield against X-ray and gamma-ray radiation. Lead, in its pure form, is brittle and cannot be worn as apparel. To transform pure lead into a wearable radiation shielding material, it is mixed with binders and additives to make a flexible lead vinyl sheet. The lead sheets are then layered to the desired thickness to achieve the required lead equivalency and incorporated into the radiation shielding garment.

Lead Composite Shielding

Lead composite shielding is a mixture of lead and other lighter weight metals. These lead-based composite blends are a proprietary mixture of lead and other heavy metals that attenuate radiation. Lead-based composite blend radiation shielding garments are lighter than regular grade lead, and are available with the same lead equivalency protection levels.

Non-Lead or Lead Free Shielding

Non-lead and lead-free shielding materials offer the same protection levels as lead-based composite shielding. Non-lead shielding materials are manufactured with additives and binders mixed with attenuating heavy metals and fall into the same category of materials as lead that also absorbs or blocks radiation. These metals include tin, antimony, tungsten, bismuth and other elements.

These core radiation shielding material options have their own unique benefits and features. There are several factors you will want to consider when choosing your shielding option, like the specific procedure being performed, the length of the procedure and its frequency.
