When considering options for radiation shielding, the most important thing is to use materials with a high density. Lead and tungsten are the most common materials to shield gamma radiation, however, they both have different advantages.

Our lives are impacted by industrial x-ray and Non-Destructive Testing (NDT) as they play a crucial role in ensuring safety and reliability of everything from aircraft parts, to bridges and power stations. However, this also puts equipment operators and sensitive components at risk of being exposed to harmful radiation. MarShield designs and manufactures custom modular radiation shielding rooms, protecting all stakeholders by maintaining a safe work-place environment.

When it comes to radiation shielding in any industry, often a standard off the shelf product is not the best fit to maximize shielding effectiveness and efficiency in your operations. Clients require custom radiation shielding solutions that are designed to meet their specific needs.

Mars Metal was contracted by a large commercial construction company to build accelerator doors for a cancer care facility in Washington, USA. We were brought on board due to our expertise in fabricating and installing accelerator doors. What made this particular project unique was that one door was to be installed immediately to get an accelerator room operational and the second door was to be installed at a later date. We began the fabrication process working with the physics report provided by the customer to custom design a set of doors. Adjustments were made on our approval drawings and the doors were designed to the customer’s exact specifications to ensure installation on-site would be smooth.

An X-ray is produced by energy released from an accelerating electron and 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. 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. Construction of hospitals and dental offices take steps to include radiation shielding that will reduce long term exposure from x-rays.

The Nuclear industry often requires large radiation shields made primarily from lead. One common method is to pour lead into a steel fabrication. The metal shell protects the lead in a durable casing that holds up better over time. This also ensures that any risk of lead exposure is minimized as the lead is sealed in an outer casing.

An area where material science is advancing the field of radiation shielding is in the development of non-lead shielding materials. Lead is used today because it’s cost-effective, easy to work with, and most importantly has the ability to reduce gamma radiation. One drawback of lead is that it is a toxic substance if ingested into the body. Given the toxicity, innovations are being made to produce thinner, more flexible and effective non-lead shielding solutions. Specifically, polymers are being utilized for their material properties. They are infused with tungsten and other metals to produce a new generation of shielding products.

Previous posts that I have written have mostly dealt with shielding gamma and neutron radiation, however there are other forms of radiation that should be shielded in certain situation. Radio Frequency (RF) waves are a form of electromagnetic waves produced by electronic devices and networks such as cell phones or radio towers. These waves can cause interference with other sensitive electronic devices. RF and electromagnetic waves can be shielded by enclosing an area with conductive material and electronically grounding the shield. This is also commonly known as a Faraday Cage. The effectiveness of the shield will depend on the material used, thickness of the material, and what frequency the waves that need to shield are.

Designing and building radiation shielding can pose a variety of challenges, such as limitations on space, price, weight, and installation. One of the most versatile forms of shielding material that is used to overcome these challenges is lead—it’s less expensive, readily available, and easy to process into finished radiation shielding products. Lead is used in the construction, nuclear power, non-destructive testing, academic, and medical fields for radiation protection and shielding.

In the last article I wrote on radiation shielding materials, I explored the factors considered by a shielding materials expert when designing radiation shielding. Lead, tungsten and concrete are all very effective forms of shielding that have their advantages and disadvantages, but one downside is these materials are not transparent. Two common and reliable solutions to provide safe shielding; lead X-Ray glass or clear lead acrylic. Both materials are used in variety of application, from windows in NDT Rooms, to small windows on tungsten vial shields. While lead glass is typically more economical than acrylic, both are materials that a shielding materials expert would consider when presented with the challenge of creating transparent radiation shielding.
