Collaborative innovation in radiation protection requires strong partnerships.

Yesterday, representatives from MarShield and Eclipse Automation visited McMaster University’s Centre for Advanced Nuclear Systems (CANS).

Together, Joe Darocha, Trevor Williams, Michael Trudeau, Syed Abidi, and Walter Silva toured the facility and reviewed advancing nuclear technologies.

A special thank you to Josip Zic and the McMaster team for their hospitality, sharing their knowledge, and providing an excellent tour of the facility.

Can your radiation shielding stand up to neutrons?

Plasti-Shield® borated polyethylene, supplied by MarShield, is built to help attenuate and absorb neutron radiation in medical, nuclear, and industrial environments.

With 5% boron content by weight and a high hydrogen concentration, Plasti-Shield® helps address fast neutrons, thermal neutrons, and secondary gamma rays in spaces where shielding performance matters.

It is used in medical vaults and doors, particle accelerators, hot cells, nuclear storage and transport containers, and nuclear detection systems.

Over 200 sheets are in stock and ready to ship.

The nuclear industry is entering a period of significant change. How are facility designs keeping up?

As next-generation applications like SMRs, hot labs, and research facilities are introduced, early integration of radiation shielding remains critical to protect personnel, avoid structural conflicts, and ensure regulatory approval.

Key planning criteria include:

- Balancing Performance with Spatial Limits: Achieving target attenuation within strict structural, weight, and operational limits.

- Strategic Material Selection: Matching materials directly to radiation types, including lead for gamma attenuation, tungsten for localized density, and borated polyethylene for neutron moderation.

- Maintaining Structural Integrity: Eliminating radiation shine paths across critical doors, seams, and connection points.

Great day spent at Glen Abbey for The 31st Annual Ambassador’s Cup Golf Tournament on Monday.

Hosted by The Japan Society, the event brought together business leaders to strengthen ties between Canadian and Japanese commercial and cultural communities. Ali Tharia, Syed Abidi, Kevin Milne, and Walter Silva had a great round of golf.

Thank you to The Japan Society for hosting a memorable event.

Behind every diagnostic image is a room built with purpose.

X-ray. CT. MRI. RF environments.

Each imaging space has its own shielding requirements, and those details matter long before the first scan happens.

MarShield supports medical, veterinary, dental, and healthcare facilities with custom radiation shielding solutions engineered for safety, compliance, and real-world use.

SMR shielding has to solve more than one problem at a time.

Project teams need to balance shielding performance with tight space constraints, integrate shielding into the facility design, and meet compliance requirements without slowing the build.

MarShield brings decades of experience designing and manufacturing radiation shielding for nuclear environments. Our team works with engineers, project teams, and facility operators to develop shielding solutions that align with performance requirements, facility layouts, and regulatory expectations.

As SMR and microreactor projects continue to grow, that experience helps teams move from concept to installation with greater confidence.

RF shielded enclosures still need airflow. They also need shielding performance to stay intact.
MarShield RF waveguide air vents are used to treat HVAC access points into RF shielded enclosures. Each vent assembly uses hex cell honeycomb waveguide geometry sized to support the design specification while allowing air to move through the enclosure.
For projects where ventilation, shielding integrity, and enclosure performance need to work together, waveguide air vents help bridge the gap between airflow and RF protection.

The 16th Annual OCNI Charity Golf Tournament brought together professionals from across the nuclear sector yesterday for direct collaboration and industry alignment.
MarShield supported the event as a Hole Sponsor, with Walter Silva and Syed Abidi representing our team on the green.
Backing these initiatives reinforces our long-term commitment to the partnerships driving this high-stakes industry forward.
Thank you to OCNI for a wonderful event!

MarShield will be at the OCNI Annual Charity Golf Tournament on June 23, 2026, at Lionhead Golf Club in Brampton.
Walter Silva, Kevin Milne, and Syed Abidi look forward to connecting with nuclear industry colleagues for a day of golf, networking, and community support. This year’s tournament supports Dnaagdawenmag Binnoojiiyag Child and Family Services, an Indigenous Child Well-Being Agency serving children, youth, and families across Central and Eastern Ontario.
We look forward to seeing you on the course and supporting a meaningful cause.
