Established in 1991, the research center at Karaj produces isotopes for medical and agricultural applications. [1] It is also believed to be involved in undeclared nuclear research. The facility operates a 30MeV cyclotron supplied by Australia that Iran used in secret laser enrichment experiments. [2] It comprises the Departments of Nuclear Agriculture, Ion Beam Applications, Materials Engineering, Nuclear Electronics, Nuclear Medicine, and Health Physics. [3] Iran also declared that Karaj has housed laser enrichment equipment from Lashkar Ab'ad since May 2003. [4] Karaj also stores mass spectrometry equipment and radioactive waste at Karaj. [5]

The Karaj facility is the target of both U.S. and UN sanctions. [6]
