MarShield Radiation Shielding

MarShield Radiation Shielding is a custom manufacturer of radiation shielding products and supplier of shielding materials. Imaging Community Exchange (ICE) recently interviewed MarShield Radiation Shielding Vice President Jim Chesla to find out more about the company.

Q: How does your company stand out in the medical imaging field?

Chesla: The benefit of “custom” is that we offer solutions to make our customers more efficient. We often say “buy what you need, not what is available and off the shelf. Customization can also improve radiation protection and assist in meeting ALARA goals. Our slogan is “Challenge Us!” We’ve seen a lot and work with everyone from engineers, architects, health physics/safety managers, contractors and purchasing staff to understand your challenges and get to a solution that maximizes the value of your purchase. Value extends well beyond the initial purchase of your equipment!

Q: What are some of the services and products you offer?

Chesla: MarShield offers products for use in existing settings and in construction of new procedural rooms and settings. Shielding material options include lead, heavy tungsten, non-lead alternative and borated polyethylene. For operational settings, MarShield manufactures X-ray modular shielding rooms, wall panels and control booths, radioactive storage vaults and cabinets, lead curtains, mobile and stationary barriers and portable shields.

For sites under constructions we offer shielding materials including interlocking and straight lead bricks, high-density concrete block, sheet lead, lead-lined drywall and plywood, lead lined doors, leaded glass and acrylic windows, non-lead alternative shielding material options, and RF shielding materials and install services.

MarShield manufacturing capabilities include fabrication, machining, coating, engineering, testing and more.

Q: What has been your company’s biggest achievement?

Chesla: MarShield’s biggest achievement is our longevity and stellar reputation in the industry. MarShield has been providing radiation shielding solutions to the diagnostic imaging, nuclear medicine, nuclear energy and non-destructive testing markets for over 40 years.

Q: What is on the horizon for your company?

Chesla: Oddly enough, not knowing what challenges lurk around the corner is most exiting for us! MarShield continues to come up with new shielding concepts, shielding materials including non-lead alternatives, and new designs and manufacturing technics to improve on the value that we bring to our customers.

Q: Is there anything else you would like our readers to know?

Chesla: Don’t contact us in the middle of designing or planning your shielding requirements. Contact MarShield from the beginning. We’ll assist in getting the project underway quicker, more efficiently, and most economically; and at the lowest cost possible.
