The Radiation Laboratory at the University of Massachusetts Lowell serves the Department of Applied Physics among others. The laboratory contains the University of Massachusetts Lowell Research Reactor (UMLRR), a 1 MW pool-type research reactor that has been operating since 1974, along with a 300 kCi Co-60 gamma ray source and a 5.5 MeV Van de Graaff accelerator.

The first startup was on January 2, 1975. A budget for the reactor is not provided by the university or the state; funding comes from customer irradiations, grants, and the United States Department of Energy.

The UMass Lowell reactor has been one of the many research reactors to make the conversion from high-enriched uranium (HEU) to low-enriched uranium (LEU) as a part of anti-terrorism security measures. The used HEU fuel was reportedly shipped to the Savannah River Site. The original shipping date was June 2002 but had been postponed many times. As of present-day the shipments have been made and the reactor is in operation with LEU.

Neutron irradiation facilities at the UMLRR include: 1x 8-inch beam port, 2x 6-inch beam ports, in-core radiation baskets & flux trap, thermal column, and fast neutron irradiator (FNI).
