If you have x-rays or radiation treatment for illness, you need prevent the harmful rays produced by the equipment from spilling out into the surrounding hallways and rooms. Some materials prevent penetration of dangerous rays better than others. In fact, lead shields for radiology applications are one of the best protections you can use and there are many reasons why.
When you see or touch a solid material, it might look like impenetrable. In reality, tiny things pass right through the human body and brick walls with little to no resistance. That’s because atoms (which make up matter) are not completely solid and their arrangement (density) can vary a great deal.
It’s not easy for radiation to penetrate dense materials, but what makes lead (like the lead shields for radiology) denser than most? It has to do with its atomic structure. In other words, the atoms are packed more tightly together than in other materials. This gives lead a high amount of mass, so it’s more difficult for even the tiniest of things to pass through.
You can find a few materials that have a greater density than lead. For example, gold is denser and so is platinum. Tungsten is another material that’s denser than lead. However, compare the price of lead shields for radiology use, to gold lined walls, aprons, or other materials to protect patients and workers from harmful radiation. This cost is beyond most budgets today.
Lead is the most cost-effective material for radiation protection today, and Mayco Industries is there to help you get the best protection at the most affordable costs. Mayshielding (our radiation protection division) produces a wide range of lead plate and sheet material for radiation shielding. We carry many stock sizes and can custom manufacture what you need. Call 800-749-6061 today for more details.
Planning the correct types and levels of protection in medical, dental or research and testing facilities to protect against radiation contamination is an essential part of any project. At Mayco Industries, our team of engineers and design consultants is here to assist your team in any type of project that requires radiation shielding.
It is essential in many applications to rely on more than one type of radiation shielding. Some shielding is used to protect individuals, both patients, and technicians, while other materials are required to prevent radiation from leaving a specific area and contaminating surrounding areas.
Lead bricks are often used in construction or testing applications. They can be designed to the given thickness required to provide the level of protection needed given the radiation source and strength.
Typically, these bricks are used in walls or around barriers in a room or testing area. The bricks can be designed to lock, which allows for easy construction and configuration that can be changed as needed.
Different thicknesses and alloys in sheet lead is a highly effective form of personal radiation shielding. Lighter in weight than other types of shielding, it is not pure lead but combines a variety of materials to make it flexible and practical certain applications. Multiple thin layers are used to create the sheets, and protect against both gamma and x-ray radiation.
Lead lined or x-ray glass is used to provide a transparent and highly protective barrier in any application. This glass is available from Mayco Industries in a variety of thicknesses to meet your protection needs. We also sell lead lined telescopic frames, ensuring full protection around the lead-lined glass in any facility.
Working in any type of industry where there is the potential risk of exposure to x-rays or gamma rays is always a risk. By ensuring you have the right type of x-ray lead shields in your protective clothing you can have the confidence in knowing you are protected fully by the smock, garment, or shield.
It is important to realize that not everyone will need the same level of protection. Knowing the level of radiation you will be exposed to will be critical in choosing x-ray lead shields. While there is no harm in having a higher level of protection than necessary, the weight of the more protective shields is higher than that of the shielding materials designed for lower exposure levels.
For lead shielding products, we can provide shielding as thin as 1/64”. We offer our own MayShielding line, which offers sheet and plate lead to any specific alloy and size required for use as x-ray lead shields. We can create sheet alloy that is as thin as 0.015 inches to up to five inches in thickness. Designed to provide the protection you need, this is an ideal option for any type of application from medical and dental offers to use in nuclear or pharmaceutical applications.
Other options include protecting the physical space with lead-lined gypsum board, lead-lined plywood, and our x-ray glass and specialized protective frames. Combining all of these shielding factors can create the ideal space that is right for your specific protection needs.

A lift truck pulls up to a pallet of heavy iron. As the operator inserts and then lifts the forks, he notices the back wheels coming off the ground. The smart operator sets the load back down and doesn’t lift it. Let’s look closer at what is happening in this scenario, to help you understand how lead counterweights work and why they are so important.
What is a Counterweight?
A counterweight is the stabilizing part of a balancing system for a lifting mechanism or machine. They are used in lift trucks, draw bridges, elevators, cranes, and any machine that lifts a lot of weight. A balance system has a main support or fulcrum. This is the tipping point, and by spacing a counterbalance weight on the opposite side of the load, the system balances. This prevents machines like cranes and lift trucks from tipping over when they lift heavy loads.
In the opening scenario, a lift truck operator slid his forks underneath a load that was too heavy for the truck to safely lift. The lack of sufficient weight or the use of non lead counterweights in the back of the truck could not balance out the load, and that’s why the back wheels came off the ground.
Had the operator continued to lift the load, the truck (along with load) would eventually tip over. The counterbalancing weight is just as important as any other part of the lifting machine.
Most manufacturers prefer to use lead counterweights for their machines, for several reasons:
- Lead is very dense
- You need less volume of lead than most other materials
- Space saving – smaller weights can be used
- Lead is naturally anticorrosive
- Lead can easily be formed or machined to custom configurations
Mayco Industries creates custom counterweights for large projects like drawbridges. We also make elevator, marine and aerospace applications, and shot ballast in stock or custom sizes. Call us toll-free today at 800-749-6061 for more info.
One of the products we offer at Mayco Industries is lead wire spool. Our lead wire ranges from the smallest standard diameter of just 0.093 inches to up to 0.750 inches in diameter. For easy handling, we can provide the wire in cut lengths, but most of our customers choose to order the wire on a drum or spool.
The lead wire spool typically contains a length of the wire equal to approximately 10 feet. We have a variety of spool sizes from 50 lb to 250 lb. Alternatively, we can coil it into drums for larger orders, if requested.
Uses of Lead Wire
We work with many different industries and many different businesses and manufacturers using lead wire spool. The very finest of the diameters of lead wire is a common addition to both hand-tied fishing flies as well as those produced commercially.
Lead is a good option for this application as it is heavier than other types of metals, so it adds weight that can be evenly distributed across the fly. Additionally, it is resistant to corrosion, so that it will last for an extensive period of time even when constantly in the water.
A very common use for our lead wire is our specialized bullet wire. This is sold in a variety of diameters and alloys to match with the size of dies in use in your system. The wire replaces the need to try to cast cores. Instead, it makes a ready-to-use application that saves time and cost in the production of bullets.
For large scale ammunitions manufacturing, these cost and time-saving factors add up, reducing the overall cost per unit of production. We can provide information on the specific alloys in our bullet wire and ensure you get just the diameter of lead wire you need for your specific production requirements.
