MarShield Shielding Solutions to Reduce Long Term Exposure to X-ray Radiation

An X-ray is produced by energy released from an accelerating electron and the resulting radiation can pass through some; but not all material. The x-ray radiation then interacts with a detector and forms an image of the inside of an object or person. Because of the ability to “look through” materials that the human eye cannot see through, x-rays are used in a variety of industries which can include dental, non-destructive testing (NDT) and most importantly, the medical industry. While x-rays are a valuable diagnostic non-invasive tool with minimal risk to the patient, repeated long term exposure to x-rays can be harmful. In the construction of hospitals and dental offices there are many steps taken to include radiation shielding that will reduce long term exposure from x-rays.

One of the more commonly used material to provide shielding is sheet lead; as it comes in standard thicknesses that are adequate o shield x-ray radiation. Sheet lead can be installed on walls with screws and drywalling can be placed over top. Or; the lead can come already fixed to the drywall. For thicker pieces of lead, 3/8” plywood can be used to provide more support to each sheet. It is important when using lead sheet, lead drywall or lead plywood to cover up the seams between where the panels of shielding meet or where the screws pass through the lead. X-ray radiation travels in straight lines so seams need to be covered with lead strips or lead disks to cover screws.

Panels, or pre-fabricated lead lined x-ray rooms. All three of these options use a system that encapsulates the lead in plastic and steel, minimizing the risk of lead exposure. Mobile barriers can be moved around and placed where needed. Lead glass shielding is also available to allow safe viewing through the shielding. MarShield EZ Shielding Panels can be easily installed on existing interior walls for added protection. Fully completed x-ray rooms are mostly used in the NDT industry, where x-rays need to be shielded in an open area. The rooms are free-standing and can include lead glass windows, and doors. Generally, lead shielding offered for these products start at 1/32” up to ¼” for x-ray shielding.

Another product that can be used to shield x-rays is MarShield’s lead curtains which provide an economical solution to provide shielding to areas that a permanent wall or barrier would not be suited for; like a doorway. The curtains come in a variety of sizes and colours and are easy to install, with our heavy-duty overhead tracks. The lead equivalencies offered with lead curtains are 0.25mm up to 1.5mm. The outer materials of the curtains are nylon, vinyl or weblon.

If there are health and safety restrictions or concerns with using lead, one product MarShield can offer is Nanotek X-Ray Shielding. This product is a material that has been developed to provide an alternative to lead radiation shielding. The result is a polymer-based shielding material.  It can be made into thin materials to replace sheet lead and installed on walls with an adhesive backing, or the material can be used to provide thicker shielding in the form of interlocking bricks.

X-rays are an essential tool in the healthcare industry, providing important diagnostic imaging in a quick and non-invasive method. Technology has ensured that a modern x-ray provides minimum radiation dose to patients, however, long term X-ray exposure can be harmful. Therefore, radiation shielding is important to install in x-ray imaging facilities.
