Nuclear Shields

What Nuclear Shields does

Nuclear Shields B.V. is a Dutch radiation shielding manufacturer founded in 1970, headquartered in Vortum-Mullem, Netherlands, with additional offices in the United States and Australia and production facilities across two factories on three continents. The company designs, engineers, and fabricates radiation shielding products using lead, tungsten, lead glass, and bismuth to attenuate gamma and X-ray radiation for nuclear medicine, radiology, imaging, nuclear energy, homeland security, and scientific research applications. Its portfolio spans more than 900 catalog items across five categories — Nuclear Medicine, Radiology, Imaging Solutions, Radiation Shielding, and Nuclear Energy — ranging from handheld tungsten syringe shields (0.16 kg) to large multi-layer nuclear waste containers (NWC1) with a 50–100 year design life. All production is conducted in-house, including lead casting in a dedicated foundry, 5-axis CNC machining, welding, spray painting, assembly, and quality control, supported by ISO certification within the Van Mullekom Group.

The company's business model is exclusively B2B through an authorized distributor network; the webshop is restricted to verified distributor accounts, and direct sales to end customers are not accepted. Standard catalog products are priced per unit with login-gated pricing, while custom-engineered solutions are quoted on a per-project basis. Revenue streams include one-time equipment sales, custom shielding solutions, and aftermarket replacement parts such as adhesive lead sheets and individual lead bricks. Customers include hospitals, radiopharmacies, nuclear medicine departments, nuclear power plants, research laboratories, government agencies, and OEM system integrators, with end markets served in healthcare, nuclear energy, scientific research, and security.

Marketing and demand generation rely on attendance at three major international congresses (EANM, IEEE NSS/MIC/RTSD, SNMMI), an email newsletter, Instagram, and organic website/SEO content. No public pricing is disclosed, no revenue is reported, and the firm operates without external venture or private equity capital signals, with ownership apparently aligned with the Van Mullekom Group rather than financial sponsors.
