Imen Gostar Raman Kish, a company controlled by senior officials in Iran's Organization of Defensive Innovation and Research (SPND), a military nuclear research institute, advertises equipment containing radiation-detection tubes manufactured by U.K.-based company Centronic Ltd. The Mindex Center, the export agency of Iran's Ministry of Defense and Armed Forces Logistics (MODAFL), also advertises the same equipment. The chairman and vice-chairman of Imen Gostar are both senior SPND officials sanctioned by the United States, and its CEO traveled to Russia in 2024 as part of an Iranian delegation seeking technologies usable in nuclear weapons development. Imen Gostar also claims to sell plastic-scintillator detectors that contain components produced by U.S.-based company Eljen Technology as well as a photomultiplier tube produced by a brand controlled by Exosens, Centronic's France-based parent company. There is no evidence that the Western manufacturers knowingly sold the components to Iran.
