"Hamid Reza Asefi said Iran had done research in the past on polonium but stopped 13 years ago. The report by the IAEA was nothing new", he was quoted by journalists in Tehran."

Hamid Reza Asefi said Iran had done research in the past on polonium but stopped 13 years ago.

Since there are samples with the Polonium, this is very easy to check: Po-210, with half-life of 138.39 days, decays into the stable Lead isotope Pb-206. After 13 years almost nothing of the Polonium remains as it has been divided 13*365/138.39 or about 34.29 times. Just measure the relative amounts of Po and Pb. My 2 cents is that he is lying.
