Why interlocking lead bricks are one of the best materials for radiation protection

Lead is one of the best materials used in radiation protection. Interlocking lead bricks offer outstanding features and benefits because of their versatility. They are available in a wide range of standard and custom sizes, including corner units.

Lead is the leading material for radiation attenuation because of the high density and high atomic number of lead. Radiation shielding effectiveness is based on the density of the shielding material, its resistance to damage, its thermal properties, its cost and availability and, most importantly, its radiation attenuation effectiveness. Lead is a material that meets all these criteria. Lead is effective at blocking gamma rays, x-rays, and other types of nuclear radiation. But the specific use of lead in the form of interlocking lead bricks is especially invaluable because of their flexibility of use in the field of radiation shielding/protection. Here’s why:

A major advantage of using interlocking lead bricks for radiation protection is the dual benefit of the intrinsic properties of lead as a radiation barrier and the flexibility of use for this form of lead. Other lead shielding materials commonly in use are: lead clad building materials, lead laminated panels, lead sheet and foil, and even lead glass, to name some of the more popular forms.

How Babbitting Protects From The Galling Of Metallic Surfaces

Those in industry who work with metals, metal components, and metal machinery, and are familiar with the frustration of machine and component failure due to the galling of metallic surfaces, will appreciate a solution to this problem through a practice known as “babbitting.”

Babbitting refers to the coating of a metal surface, casting, or bearing with a Babbitt metal; which is essentially a different material from that which is being coated. A Babbitt or Babbitt metal is one of any number of metal alloys used to protect from the galling of metallic surfaces.

Galling refers to a type of severe abrasive wear on metallic surfaces; an abrasion that can occur between at the interface of two contacting rubbing or sliding metal materials. It is, in effect, a microscopic transfer of material between metallic surfaces. Galling is also sometimes referred to as cold welding. It can take place between surfaces like bearings and casings that are under sufficient load and in motion with friction to cause the transfer of metallic material, thereby leading to metal component failure.

Some of the principal factors that can affect galling include the properties of the metallic materials (such as surface hardness and microstructure), the applied load, the contact area and degree and intensity of movement, the duration of contact, and even the environment and design of the materials.

Application of Anodes in Marine and Defense Industries

The outer components of marine and defense vessels are constantly being threatened by the surrounding water. Over time, corrosion can lead to a loss of integrity in the structure, hence the use of marine anodes.

Understanding Corrosion

Most metals immersed in water are subject to rust and disintegration caused by electrochemical corrosion. Marine anodes are designed to fight electrochemical corrosion by using the process of galvanic corrosion.

Essentially, galvanic corrosion is caused by placing less-active metals near highly active metals. The process requires the active metal to “sacrifice” itself, attracting the galvanic corrosion to it while protecting the critical components. In this instance, the sacrificial active metal acts as the anode, and the valuable metal the cathode.

Marine Anode Optimization

Anodes aren’t meant to last forever – their purpose is to absorb natural wear, thus protecting surrounding valuable metals from the threat of corrosion.

Zinc Anodes In The Oil And Gas Industry

Zinc anodes protect the metal parts of submerged structures by inhibiting the rate at which the metal corrodes. Sacrificial anodes are the main component in cathodic protection, a technique used to control the corrosion of a metal by setting it up as the cathode of an electrochemical cell. In other words, a sacrificial metal that corrodes more easily is set on the surface of whichever metal needs to be protected. Since this metal corrodes more easily, the metal underneath is protected. Oil and gas industries both benefit from this electrochemical response, because both require the use of structures that may be submerged underwater for extended periods of time. Two metals submerged underwater create a kind of cell that corrodes over time, a process known as galvanic corrosion.

Rather than preventing the process of corrosion entirely, zinc anodes or sacrificial anodes, known colloquially as “zincs”, override the galvanic corrosion between the two metals they are designed to protect.

Benefits of Using Lead Plumbing Joints

Those in need of lead plumbing joints – as well as other lead-based products – will appreciate the expertise and deliverables of Canada Metal. 

Lead is a very malleable metal that offers extensive benefits in plumbing applications. Lead is extremely stable and endurable. The ductile property of lead – and the fact that it can be manufactured and formed for near endless purposes – makes it ideal for a range of piping functions and particularly as piping, wiped joints and plumbing joints.

By way of illustration, lead is resistant to corrosion by such things as home cleaning products and chemicals, thereby making it an ideal material for use in infrastructure and for waste water applications. Plus, the combined attributes of lead make the metal especially suitable to scenarios where there might be concerns about unsteady ground, as in earthquake-prone regions or along coastlines. And when it comes to repairing existing lead pipes, including for piping systems that might be as old as a century or more, lead plumbing joints quickly come to the rescue as a virtually indestructible material.

In plumbing applications, lead makes an excellent moisture barrier with a durability that can outlast most buildings, structures, and groundworks. Lead is also remarkably versatile: Along with its many uses as piping joints, stubs and bends, lead is renowned for its properties in radiation shielding.

Radiation Shielding and Applications of Cadmium and Lead in Medicine

Medical professionals appreciate the significance of specialized metal products and the functions these metals provide in hospitals and medical research, particularly with regard to radiation shielding. 

Metals cater to a range of requirements in medicine for diagnostic and treatment purposes – but the full range of applications for certain high-value metals applies to a number of specializations. Central to this is radiation shielding. Radiation shielding is of utmost importance across healthcare disciplines such as dentistry, veterinary science, and medical industries as well as research. The primary metals related to radiation shielding are lead and cadmium – The most frequently used is lead in various form including, brick, both flat and interlocking, lead sheet, blocks, tubes as well as cadmium sheet. 

Cadmium metal is a metal that’s found naturally in the Earth’s crust. It is highly malleable and is rated 67 in abundance out of 90 naturally occurring elements. Cadmium readily absorbs neutrons and is used in the nuclear industry for neutron shielding and in the manufacture of control rods for nuclear reactors. A specific application of cadmium sheets, therefore, is for neutron radiation shielding. Industries where cadmium sheets are required range from medical research to nuclear power generation.
