Constructed in the early 1990s, the Der Al-Hadjar Nuclear Research Center houses Syria's only research reactor, the Chinese-supplied SRR-1 Miniature Neutron Source Reactor. The bulk of Syria's nuclear-related work takes place at the Center. Research includes nuclear physics and chemistry; use of radiation and radioisotopes in medicine, agriculture, biology, and geology; exploration of radioactive ores; management and procedures for the use of radioactive resources; protection from radiation; and the effects of radiation on humans and the environment. The facility is subject to IAEA inspections under Syria's safeguards agreement with the IAEA. In 2008 and 2009, environmental samples taken by the IAEA revealed particles of processed natural uranium that were not in Syria's declared inventory.  Syrian officials later acknowledged performing experiments irradiating uranyl nitrate at the SRR-1. After inspecting the source of the uranium particles at the phosphoric acid pilot plant in Homs and revisiting the SRR-1, the IAEA found that Syria's declarations were consistent and reverted to the "routine implementation of safeguards" at Der Al-Hadjar.
