Nuclead Inc.
Part 3: Custom Radiation Shielding Capabilities.
Often a specific radiation shielding application will require that
standard lead shielding components be further machined or
finished to meet exact specifications. This may involve machining
the lead products into custom shapes or may involve a custom or
finer finish to a part.
In this third article regarding Nuclead radiation shielding
expertise, we describe the company’s custom fabrication,
machining and finishing capabilities.
Nuclead’s custom radiation shielding products
As well as being the largest wholesaler of radiation shielding
products in the North Eastern USA, Nuclead has extensive
manufacturing and machining capabilities that allow for the
fabrication of any custom lead shielding products.
Our custom precision lead services include mold fabrication and
pours, 3D and CNC machining, stamping and cutting, welding and
lead assembly, lamination and PSA adhesive application. All our
processes are governed by ISO 9001:2008 quality control
practices.
Many of the world’s finest companies and universities have used
Nuclead lead machining capabilities. Programming capabilities
include the latest in CAD/CAM software in both 2D and 3D.

2. Lead assemblies – Radiation shielding requirements for
equipment such as MRI machines require the fabrication of
complete assemblies that consist of multiple components
including lead shielding, aluminum housings and many other
components assembled per custom drawings. Various processes
are involved in the building of these custom lead assemblies,
including lead lamination, joining via lead adhesives or lead
welding, lead stamping, lead machining, and lead cutting.
Lead, aluminum, other metals and weldments are fabricated and
then assembled together in accordance with blueprints supplied
by the customer. The finished assembly can be plated, powder
coated or painted and then delivered ready to be assembled into
the final product.
An MRI machine is a good example of this type of assembly, and
Nuclead has extensive experience in building this type of complex
radiation shielding product. The MRI machine is a large piece of
equipment that allows a patient’s body to scanned using both
magnetic fields and radio waves. It is necessary to provide
radiation shielding as part of the machine construction.
This type of sophisticated lead shielding component is required
both protect the patient from excessive radiation and to shield
the equipment from extraneous local interference caused by cell
phones, computers or other types of equipment.
Nuclead has many years of experience building these kinds of
sophisticated items and has all the necessary capabilities in house.
Lead laminates – Lead sheets are typically laminated to a
supporting base via the use of pressure sensitive adhesive (PSA).
Nuclead laminates lead sheet or machined lead items to any

3. component per customer specifications. Whether fabricated by us
or customer supplied, climate controlled facilities will ensure that
the correct temperature and humidity is maintained to ensure the
highest quality bond.
Machined lead bricks – In certain applications it is important that
the lead bricks are properly machined and finished to a high
quality. Particularly for high energy radiation shielding and
gamma ray blocking, where the nuclear bricks must be able to be
stacked with no gaps. Often high energy radiation bricks are
machined to have tongue and grooves on four edges to allow the
lead bricks to be interlocking.
Nuclead is expert at machining radiation shielding bricks to high
quality finishes and to custom configurations. For example
Nuclead has shipped tons of lead bricks for radiation
environments to state universities, machined in custom shapes
and sizes to meet specific radiation shielding needs.
Another example is the Department of Energy requirements for
machined radiation bricks to high tolerance and finish
specifications.
Lead Welded products – Nuclead welds lead items with any alloy,
with any diameter wire required.
Nuclear casks – are heavily radiation shielded lead containers that
are used to store and/or transport highly radioactive materials
such as spent nuclear fuel rods. Nuclear casks are typically cast
from lead pours in order to ensure a continuous container.
Radiation casks are designed to maintain integrity under
hypothetical crash conditions and are thus tested to withstand
crush damage, fire, water and puncture.

4. Nuclead has lead pouring capacity of up to 100,000 pounds and
can have the finished nuclear casks examined with gamma ray
inspection, to ensure integrity. Nuclead will typically manufacture
the lead cask molds per customer drawings and specifications and
will pour the molten lead to meet the specified radiation shielding
needs.
Conclusion
Nuclead can provide value added finished radiation shielding
products to custom specifications, for both sample quantities or
production quantities
This is the third article in series about Nuclead’s Lead shielding
capabilities. The previous articles described standard lead
shielding products and the large inventory of radiation shielding
products available to ship to order.
