Radiation Protection Systems

What Radiation Protection Systems does

Radiation Protection Systems (RPS), founded in 1978 and headquartered in Groton, Connecticut, is a design-build engineering company specializing in engineered controls for radiological and hazardous material workplaces. The company designs, manufactures, and sells portable HEPA filtration units (SP series, PFB series with bag-in/bag-out and housingless variants, MAC-21 series), nuclear-grade carbon adsorbers (HEGA) for radioiodine removal, AG-1 and ULPA-compliant filters, ducting components, and accessories. Its second product line covers radiation shielding, including mobile shield walls, frisking and shielded booths, counting caves, and custom engineered solutions such as reactor vessel shielding and HEPA filter cask shields. Its third product line is modular containment, anchored by the trademarked Perma-Con® enclosure system (available in Classic, EXT, and Weather-Con™ variants) plus soft-sided work tents, drum inspection hoods, and gloved enclosures. RPS products meet nuclear-grade standards including ASME AG-1 (Sections FC-5100/5110/5120/6000), ANSI N509/N510, DOE-STD-3020-2005, ASME NQA-1, UL-586, and UL-900 Class 2.

RPS serves commercial nuclear utilities (every U.S. and Canadian utility, per company claims), U.S. Department of Energy sites, U.S. Department of Defense facilities, the CDC, universities, and pharmaceutical/biopharma research companies. Since 2024, RPS operates as a subsidiary of Alpha Safety, a holding company that also includes Nuclear Filtration Technologies (NFT) and Pajarito Scientific Corporation. The company employs 11-50 staff and runs an enterprise field sales motion with dedicated coverage for the U.S. national market, U.S. commercial power, and UK/Continental Europe. Pricing is not publicly disclosed; products are sold via request-a-quote under net-30 terms, FOB Groton, with a 12-month standard warranty. Revenue is generated through equipment sales (HEPA units, carbon adsorbers, enclosures, shielding), custom integrated engineered systems, replacement filters and parts, and on-site services/training. The company maintains a $1M HEPA inventory for Just-in-Time delivery to support customer outage schedules.

Core offering

Radiation Protection Systems (RPS) designs, manufactures, and sells engineered controls for radiological and hazardous material workplaces. Its product portfolio spans three categories: ventilation (portable HEPA filtration units, carbon adsorbers, filters, and ducting), shielding (mobile shield walls, frisking booths, counting caves, lead wool blanket systems), and containment (Perma-Con modular enclosures, soft-sided work tents, drum inspection hoods, and gloved enclosures). The company also provides on-site services, replacement filters, and custom engineered integrated systems.

Product overview

Radiation Protection Systems (RPS), now part of Alpha Safety, offers a comprehensive portfolio of engineered controls for radiological and hazardous material applications since 1978. The product line centers on three core categories: Ventilation (portable HEPA filtration units, carbon adsorbers, filters, and ducting components), Shielding (mobile shield walls, frisking booths, counting caves, and lead wool blanket systems), and Containment (Perma-Con modular enclosures, soft-sided work tents, drum inspection hoods, and gloved enclosures). The ventilation portfolio includes portable filtration units across multiple series (SP-125, SP-505A, SP-700, SP-1000, SP-1600, MAC-21, 1600, 2500, and 5900 CFM) with both standard and bag-in/bag-out configurations, housingless designs, and variable frequency drive options. The PFB and PFB(H) series represent the company's flagship portable filtration lines, while custom filtration units handle specialized applications like CBRN environments. The shielding line provides radiation protection through interlocking lead panels, shielded booths, and counting caves. Containment products include the Perma-Con enclosure system (available in Classic, EXT, and Weather-Con variants for different environmental requirements) and LI-series soft-sided work tents. RPS also distributes NILFISK industrial vacuum systems and offers a complete range of filters (HEPA, ULPA, ASME AG-1 compliant, HEGA), ducting components, sound attenuators, and accessories.

Broad incumbents

• Donaldson Company: Large industrial filtration manufacturer with broad product portfolio spanning nuclear, industrial, and life sciences applications. Offers HEPA filtration and containment solutions as part of a wider portfolio rather than as a specialized nuclear niche provider.
• Clean Harbors: Large environmental services company providing hazardous waste handling, decontamination, and industrial cleaning services. Comparable in addressing radiological and hazardous material containment/cleanup needs, though primarily a services rather than equipment company.
• STERIS: Provider of sterilization, contamination control, and laboratory/pharmaceutical containment solutions. Overlaps with RPS's AEC pharmaceutical division on containment enclosures and clean air equipment for biopharma and research customers.

Direct peers

• AAF Flanders (American Air Filter): Major manufacturer of nuclear-grade HEPA filtration, gas adsorption, and air handling equipment for nuclear power plants. Direct competitor on nuclear air filtration tenders and replacement filter contracts with utilities.
• Nuclear Filtration Technologies (NFT): Sister company under Alpha Safety providing fixed nuclear-grade filtration systems, HEPA filters, and adsorbers. Operates in the same nuclear filtration niche with overlapping products (HEGA, HEPA, ULPA) and shared customer base of nuclear utilities and DOE sites.
• Camfil: Global manufacturer of HEPA, ULPA, and nuclear-grade air filtration products, including Megalam nuclear filters. Competes with RPS in supplying qualified air filtration to nuclear, pharmaceutical, and life sciences customers, with broader product breadth and global footprint.
• HEPA Corporation: Specialty manufacturer of HEPA filtration products and cleanroom/containment equipment serving nuclear, pharmaceutical, and research markets. Direct competitor in portable and fixed HEPA filtration used in radiological applications.
• Pajarito Scientific Corporation: Sister company under Alpha Safety providing nuclear instrumentation, sampling equipment, and scientific lab products. Overlaps with RPS in serving nuclear utilities and DOE sites with complementary engineered controls and instrumentation products.
• Flanders Corporation: Direct competitor manufacturing nuclear-grade HEPA filters, ULPA filters, and carbon adsorbers for the commercial nuclear industry. Competes head-to-head with RPS on ASME AG-1, ANSI N509/N510 compliant filtration equipment supplied to US nuclear utilities.

Emerging players

• Applied Engineering Controls (AEC): AEC operates as the pharmaceutical containment division within RPS but has historical roots as an independent supplier of dust, contamination, and toxic material control solutions for pharma/biotech — making it a useful comparable for the pharmaceutical containment portion of RPS's portfolio.
