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[1] 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.

[3][4] 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.

[5] The used HEU fuel was reportedly shipped to the Savannah River Site.

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).
