Dubna was founded in 1956, together with the Joint Institute for Nuclear Research (JINR), a large international research laboratory involved mainly in particle physics, heavy ion physics, transuranium elements and radiobiology. The name of element 105, Dubnium, is derived from the name of the town. One can find street names related to physics, for example Kurchatov Street and Bogolyubov Street. JINR was initially the main employer in the town but its role has been gradually decreasing with the appearance of many industrial enterprises.
