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.

The T-Flex® Shielding range is a line of new radiation shielding materials, that will save you time and reduce installation frustration! No longer compromise on shielding effectiveness when protecting those difficult to access areas. T-Flex® Shielding is the industry’s preferred non-leaded shielding alternative. It provides maximum shielding effectiveness while still keeping the weight to a minimum, allowing you to reach your advanced ALARA program goals.

Radiation shielding is often required in industrial x-ray and non-destructive testing (NDT) applications. MarShield’s broad range of radiation shielding solutions can be used to protect sensitive components and the equipment operator from x-rays emitted by industrial x-ray systems – thus enabling effective and efficient radiation protection in a safe workplace environment.

Sheet lead for Radiation Protection in laboratories, clinics, dental and medical application can be a challenge. Many contractors and architects face challenges due to space criteria and the weight of the shielding requirements. We provide Sheet lead in 12 different sizes and thicknesses from 1/32nd to 1/4” for all shielding requirements.
