Question 7

What is a Radiation Shielding Report?

Accepted Answer

Radiation Shielding Report is a document of calculations written by a licensed Radiation Physicist stating the type of material and thickness of material required to proper shield a specific x-ray room or radiation imaging room. It is a Federal requirement to get a Radiation Shielding Report for each room.

Question 8

Why do I need a radiation physicist shielding report?

Accepted Answer

There are many commonly used thicknesses of lead shielding, and no single thickness is applicable to all room types due to all of the potential unique variations of each room, wall, energy level and application. Additionally, a radiation shielding report is required for each x-ray room or radiation emitting imaging machine by Federal radiation laws and radiation environmental regulations per NCRP reports #49 and #147. Each room and wall or partition has unique factors and considerations and often times there are several lead shielding thicknesses required in each room wall by wall segment, as based on the following:

Radiation energy output produced (KVP)
Workloads / frequency of use
Distance from source and direction
Orientation of direct beam and secondary scatter
Potential occupancy factors of common walls and adjoining rooms
Wall or partition construction materials and compositions
Type of ionizing x-ray radiation (electrically produced cathode tube or isotopic radioactive source)
Controlled or uncontrolled area (monitored exposure occupants or not)
*This requirement also includes existing rooms that have a change of equipment or use and applications
*This requirement is for all types of radiation rooms such as medical diagnostic imaging, radiation treatment , therapy oncology and industrial non-destructive testing.
All rooms should be radiation survey tested by the original project physicist of record, after shielding installation is completed and prior to any occupancy and actual use.
This radiation test requirement is common sense for peace of mind and to confirm the proper radiation protection is achieved in:
The shielding report calculations and assumptions are correct
The energy output is calibrated and beam orientation is correct
The proper shielding materials and products were utilized
The shielding materials and products were installed properly.
There were no modifications or alterations compromising the shielding system

Question 9

My walls will be 8 or 10 feet high, why is the lead only up to 7 feet?

Accepted Answer

Federal regulations require the lead shielding to go to a minimum of 7 feet because very few people are taller than 7 feet. Radiation is linear so it can not go up over a wall and then come back down, it continues to travel in a straight line. However, if there is occupancy above the imaging room (more rooms on an upper level), then lead shielding will be required to the full wall height AND on the ceiling.

Question 10

When is lead shielding required on the ceiling or floor?

Accepted Answer

Ceiling and floor lead is typically only required if there is occupancy above of below the imaging room. If the imaging room has rooms below it, floor lead will be required, if there are rooms above it, ceiling lead is required. Anytime a shielding report states that ceiling or floor lead is required, it must be followed, even if there is no occupancy above or below.

Question 11

Do I need to cover the screwheads with lead discs and batten strips at every joint?

Accepted Answer

We provide 50 lead discs and one batten strips per sheet, while others charge extra for these products. The discs are not always required, but a batten strip is always required at every joint. Per NRCP report 147: "For typical shielding applications, a lead sheet is glued to a sheet of gypsum wallboard and installed lead inward with nails or screws on wooden or metal studs. X-ray images of wall segments show that insertion of the nails or screws does not result in significant radiation leaks. In fact, the steel nails or screws generally attenuate radiation equally, or more effectively, than the lead displaced by the nails. Therefore, steel nails or screws used to secure lead barriers need not be covered with lead discs or supplementary lead. However, where the edges of two lead sheets meet, the continuity of shielding shall be ensured at the joints"

Question 12

How do I find out the lead equivalency required?

Accepted Answer

A radiation shielding report is a document written by a radiation physicist. It describes the lead thickness or lead equivalency required on each wall of your imaging room. Federal law stipulates that every facility must have a shielding evaluation done for every imaging room. They are also required if something changes in the room, like replacement of an imaging machine. In some areas, this can be handled by your county health department. Sometimes, the company you bought the x-ray machine from can acquire one for you. Due to a perceived conflict of interest, we cannot be involved in the shielding report acquisition. But if you have a shielding report and don't know how to decipher it, you can email it to us with your quote request and will we quote the proper products.

Question 13

What is Safety Rated Glass, and When Is It Required?

Accepted Answer

Safety-rated glass, often referred to as impact-resistant glass, is designed to hold together when shattered. It doesn't make the glass unbreakable, but it ensures that the shards remain bonded, minimizing the risk of injury. This is especially important in environments where glass breakage could lead to harm.

Safety glass is mandatory in a few key locations:
In doors that contain glass
Within 24 inches of any door
Within 18 inches from the floor
For traditional plate glass, this often means the glass must be tempered. However, since lead glass cannot be tempered, alternatives are required. Two common solutions are:
Laminating annealed plate glass to the leaded glass.
Applying surface security film, which is the most cost-effective method.
All safety glass used in such scenarios must comply with ANSI Z97.1 and CPSC 16 CFR 1201 standards. This compliance means there's no size limitation, allowing for interior windows larger than the usual 9 square foot restriction.

Question 14

Is There a Standard Lead Thickness for X-Ray Rooms?

Accepted Answer

There is no single standard lead thickness applicable to all x-ray or imaging rooms. Each room's shielding needs are unique and based on multiple variables. Determining the correct lead thickness involves analyzing:

The radiation output and direction of the imaging machine

Usage frequency (also known as workload)

Construction materials of walls (e.g., drywall requires more shielding than concrete)

Adjacent room type (e.g., rooms next to nurseries need more protection than storage areas)

These factors are assessed during the shielding evaluation process, often performed by a licensed physicist. Because of this complexity, it's critical to get a customized assessment for each installation.

Question 15

How Do I Know the Required Lead Equivalency?

Accepted Answer

A shielding report is a formal document prepared by a radiation physicist that specifies the necessary lead equivalency for each wall of an imaging room. This report is legally required for every facility housing imaging equipment and must be updated if:

A machine is replaced

The layout of the room changes

While some local health departments can assist with this, many customers receive shielding reports through the vendor that sold the x-ray machine. Note that due to ethical concerns, third-party manufacturers do not get involved in procuring shielding reports.

If you already have a shielding report but need help interpreting it, you're encouraged to send it to the manufacturer with a quote request. They’ll ensure you get products that meet the specified requirements.

Question 16

Can X-Ray Shielded Glass Be Used for Exterior Applications?

Accepted Answer

Yes, but not as a standalone product. Lead glass is inherently porous and fragile, making it unsuitable for direct exposure to the elements. To resolve this, manufacturers produce Insulated Glass Units (IGUs) for outdoor use. These IGUs consist of:

Tempered glass as the exterior-facing layer

X-ray lead glass as the interior-facing layer

This dual-pane approach provides weather resistance, structural integrity, and x-ray shielding in one complete system, ideal for exterior window applications in medical or research facilities.

Question 17

Can X-Ray Lead Glass Be Fire-Rated?

Accepted Answer

Absolutely. Manufacturers offer fire-rated IGUs that combine:

Fire-rated ceramic glass (such as FireLite)

X-ray lead glass

These fire-rated assemblies can be certified for up to 180 minutes, depending on their size and installation location. This makes them suitable for facilities that must meet both fire safety and radiation protection requirements.

For more detailed specifications and availability, we can provide technical data sheets or support pages for fire-rated x-ray glass products.

Question 18

Is Lead Acrylic a Viable Alternative to Lead Glass?

Accepted Answer

While lead acrylic might sound like a convenient alternative, it’s not recommended for several critical reasons:

Thickness and Weight: To achieve the same level of radiation shielding, lead acrylic must be around six times thicker than standard lead glass. For example, where lead glass might only need to be 5/16" thick, lead acrylic must be around 2 inches thick. This not only adds bulk but also increases installation difficulty.

Durability Issues: Lead acrylic is far more prone to scratching than lead glass. In high-traffic environments or where regular cleaning is required, this becomes a significant downside.

Discoloration Over Time: Perhaps the most notable drawback is how lead acrylic yellows and darkens due to radiation exposure. Within just one year, it can become so dark that it’s like “looking through a jar of honey,” making visibility nearly impossible. Lead glass, on the other hand, maintains clarity and integrity over the long haul.

Due to these significant disadvantages, most professional suppliers do not offer lead acrylic as an option.

Question 19

Does X-Ray Shielded Lead Glass Have a Tint? Is There a Clear Version?

Accepted Answer

Yes, all leaded glass inherently has a yellow tint due to the high content of lead and other heavy metals necessary for radiation shielding. However, it’s important to understand that:

This yellow tint is comparable to the green hue found in standard plate glass.

The illusion of strong tinting is often caused by the light reflecting off the edge of the glass, which is more noticeable in bright or backlit environments.

When lead glass is installed within a window frame, the edges are typically concealed, and the yellow tint is almost imperceptible to the naked eye. Most people wouldn’t even realize there's a color difference unless they specifically compare it side-by-side with plate glass under bright lighting.

Question 20

How Can Glass Break After Being Installed in a Window Frame?

Accepted Answer

Glass breakage can still occur post-installation, even in a properly framed setup. Several factors might contribute to this, such as:
Thermal stress due to uneven heating (like direct sunlight on one part of the pane)

Improper installation that puts pressure on the edges or corners

Building movement or vibrations, particularly in earthquake-prone areas

Accidental impact from equipment or mishandling

To minimize these risks, always ensure that your x-ray lead glass is installed using professional, lead-lined framing systems that allow for slight expansion, support the glass weight adequately, and cushion against direct contact with hard surfaces.

Question 21

What Happens When a Window Exceeds the Maximum Size of 96" x 48"?

Accepted Answer

When a window is larger than the standard maximum size of 96 inches by 48 inches, there are still several options to maintain x-ray shielding without sacrificing structural integrity or visibility:

Vertical Mullion

This is the most structurally sound method.

It divides the window with a visible vertical bar, which can be a visual obstruction but ensures strength and stability.

Requires a lead-lined telescoping frame.

Overlapping Lead Glass Panels

Offers a clear, unobstructed view with two layers of lead glass overlapping at the joint.

Needs a custom telescoping frame with dual glazing stops.

Standard metal frames will not support this configuration.

Lead-Shielded T-Joint

This uses a custom extruded joint to overlap the panes.

Less obstructive than a vertical mullion.

Compatible with any lead-lined frame and offers a good compromise between visibility and support.

Each method comes with its own pros and cons, and the best choice depends on your specific needs—whether your priority is clear visibility or maximum strength.

Question 22

How Do I Clean X-Ray Lead Glass Safely?

Accepted Answer

Cleaning x-ray lead glass requires a gentle approach to avoid scratching the surface or damaging the protective coatings. Here’s how to do it safely:

Use a soft microfiber cloth – This minimizes the risk of abrasions.

Apply non-abrasive glass cleaner – Avoid ammonia or alcohol-based solutions that can degrade surface films.

Spray cleaner onto the cloth, not directly on the glass – This prevents liquid from seeping into edges and affecting the lamination or framing.

Wipe gently in a circular motion, and never use scrapers, steel wool, or abrasive pads.

Dry immediately with a clean, dry microfiber towel to prevent streaks or moisture spots.

If your lead glass is laminated or includes security film, make sure to consult the manufacturer’s recommendations for care and maintenance.

Question 23

Can You Recycle X-Ray Lead Glass?

Accepted Answer

Generally speaking, x-ray lead glass is not recyclable in the traditional sense due to its heavy metal content. Unlike regular glass, leaded glass contains high levels of lead oxide, which is hazardous and can’t be processed at standard glass recycling facilities.

Here’s why recycling x-ray lead glass is problematic:

Lead contamination: Melting down lead glass can release toxic fumes and contaminate other materials.

Strict regulations: Environmental regulations prohibit mixing leaded materials with conventional waste or recyclables.

Special disposal required: X-ray lead glass must be disposed of as hazardous waste and requires handling by certified disposal companies that follow EPA or local guidelines.

However, in some regions, specialized recycling firms may extract lead from the glass using high-temperature furnaces under controlled conditions. This process is expensive and usually only practical for large-scale disposal operations. If you're replacing or disposing of leaded glass, it's best to consult your local health department or a hazardous waste contractor.

Question 24

Can Leaded Glass Windows Be Custom Shaped or Curved?

Accepted Answer

While standard x-ray lead glass is typically manufactured in flat panels, some customization is possible—but with limitations. Curved or uniquely shaped lead glass is:

Difficult and expensive to produce

Typically made using laminated methods, as actual bending of leaded glass is challenging due to its brittleness

Limited in size and curvature radius due to the properties of both the lead and the glass

In most scenarios where a curved or shaped application is necessary, alternative shielding methods like overlapping panels or angled window framing are recommended.

Always discuss your project’s requirements with your supplier, who may provide custom IGUs or composite solutions that simulate a curved appearance using flat materials at precise angles.

Question 25

Are There Frame Requirements for Installing X-Ray Lead Glass?

Accepted Answer

Yes, using the right frame is crucial for safety and compliance. X-ray lead glass must be installed in a lead-lined window frame that maintains continuous radiation shielding. Here’s what you need to know:

Standard frames won't work: Regular hollow metal or aluminum frames lack the shielding needed to block radiation.

Telescoping lead-lined frames are recommended: These allow for glass thickness variations and provide a snug fit with proper shielding overlap.

Glazing stops should also be lead-lined to maintain shielding at the edges.

Frames should be rated for the same or higher lead equivalency as the glass to prevent radiation leakage.

Improper framing can void certifications and violate regulations, so it’s always advised to purchase both the lead glass and the frame from a trusted source to ensure compatibility.

Question 26

How Long Does X-Ray Lead Glass Last?

Accepted Answer

With proper care, x-ray lead glass can last for decades. It’s an inert and stable material that doesn't degrade under normal conditions. However, the lifespan depends on several factors:

Radiation exposure levels: Prolonged and intense exposure can eventually affect clarity.

Environmental conditions: Exposure to moisture, extreme heat, or physical impact can reduce longevity.

Maintenance quality: Scratches, poor cleaning habits, or lack of protective framing may lead to earlier failure.

Routine inspections and following manufacturer maintenance guidelines will help ensure the glass maintains its integrity and shielding effectiveness for many years.

Question 27

Can I install x-ray lead glass myself, or do I need a professional?

Accepted Answer

It’s always best to have a certified installer handle lead glass installation due to regulatory requirements and safety concerns.

Question 28

What is the standard lead equivalency or lead thickness?

Accepted Answer

Many x-ray rooms require 1/16" or greater lead equivalency, but always refer to your shielding report for accuracy.

There isn't a standard lead thickness required for radiation imaging rooms. Each room has many factors that contribute to the lead shielding requirements. Some of these factors are: the energy level of the machine (how much radiation it produces and which direction it is pointed), work load (how often the machine is used), the existing construction of the room (drywall and stud walls require more shielding than concrete walls), surrounding rooms (walls shared with a children's care unit will require much more shielding than walls shared with a storage closet), and other variables are taken into consideration when a physicist is calculating the lead shielding requirement. See next question for more info.

Question 29

What is the cost difference between lead acrylic and lead glass?

Accepted Answer

Although lead acrylic may seem cheaper upfront, its thicker requirement and short lifespan often make lead glass more cost-effective over time.

Question 30

Is x-ray lead glass safe to touch or be around regularly?

Accepted Answer

Yes, the lead is contained within the glass and does not pose a contact hazard.

Question 31

Can I replace broken lead glass with regular glass temporarily?

Accepted Answer

No, only leaded glass provides radiation protection. Never use standard glass as a substitute in an x-ray shielding application.

Question 32

I need a fire rating. Can you do that?

Accepted Answer
