IAEA inspectors permitted limited access in March 2003 and full access in May 2003; modified by Iran to conceal undeclared centrifuge enrichment activities, which affected the IAEA's ability to resolve issues related to Iran's enrichment program; environmental sampling by the IAEA revealed the presence of highly enriched uranium particles which were not consistent with the nuclear material declared by Iran; in 2005, the IAEA found that the presence of these particles was likely caused by contamination from imported centrifuge components.
