The world's most important university research reactor for fighting cancer.
We'll Show You How.
MURR By The Numbers
1,000,000
Cancer treatments were made possible with radioisotopes produced at MURR.
95%
of thyroid cancer patients are cured after using radioisotopes. Liver, prostate and pancreatic cancer patients have a better quality of life and live longer with radioisotope treatment.
60 years
of safe, innovative history. Operating 24 hours a day, 6.5 days a week, 52 weeks a year — MURR is the most powerful university research reactor in the U.S., working at 10 megawatts.
Tiny atoms, big impact
A Vital Resource
MURR offers a wide range of nuclear products and services to a global community, including custom and off-the-shelf products, research and medical grade isotopes and radiochemicals, and analytical and neutron irradiation services.

MURR announces availability of Terbium-161
October 14, 2026Contact: Shayne Martin, shayne.martin@missouri.edu The University of Missouri Research Reactor (MURR) will provide Terbium-161 (Tb-161) to the global marketplace in support of emerging cancer research by the end of the year. Beginning in December of 2026, MURR will support monthly batches of radiochemical grade Tb-161, with plans to scale and transition to weekly batches produced under good manufacturing practices (GMP) by the end of 2027. Tb-161 is a chemical cousin to lutetium-177 (Lu-177), also produced at MURR, which is currently used in two FDA-approved cancer treatments. Like Lu-177, Tb-161 targets cancer cells with…
