Space Radiation Services

Space Radiation Services was founded in 2022 by Dr. Matthew Gill, a nuclear engineer with a PhD and extensive prior experience leading radiation testing and analysis for over 200 systems at Apollo Fusion (electric propulsion startup acquired by Astra). The company is headquartered in San Francisco, California, and supports dozens of customers across three continents — from component and sub-system suppliers to full satellite manufacturers and constellation providers, including Maxar, Airbus OneWeb Satellites, York Space Systems, Astroscale, LeoStella, Spaceflight, and the Air Force Research Lab.

The founding philosophy is that radiation testing should be no more difficult than other environmental testing. Space Radiation Services offers a flexible approach that balances cost, schedule, and risk, tailored to each customer's unique programme requirements — whether that means following strict MIL-STD or ECSS standards for heritage programs or developing novel approaches for New Space ventures. The company's core service areas cover Single Event Effects (SEE), Total Ionizing Dose (TID), and Displacement Damage (DD).

Services include expert advisory and training, BOM scrubbing to identify radiation-tolerant COTS alternatives with public radiation data, radiation test plan and procedure development, on-site test execution and support, shielding analysis, orbital environment modelling for LEO/MEO/GEO and deep space, mitigation guidance (ECC, watchdog timers, latch-up detection), and professional radiation test reports. The company also offers a free suite of online radiation modelling tools (TID, SEE, atomic oxygen, internal charging, and an AI-powered Space Radiation GPT chatbot) and a sister platform (spacereliability.com) focused on satellite reliability.
