>Uranium sample
Was from a stolen black market deal. The Russian's wanted to determine whose it was, US or Ukrainian(Russian) and we had to meet them to pass the sample.
Here's the background.

The uranium sample that Sumbat Tonoyan and Hrant Ohanyan were peddling is thought to have been stolen several years ago. US tests have confirmed it is 89.4% enriched, usable in a nuclear warhead. The Armenians only had 18 grams, but had been told by their supplier in Armenia that much more was available. They smuggled it into Georgia by train in a cigarette box lined with lead to fool radiation sensors at the border. Tonoyan, a 63-year-old who once ran a successful dairy business but gambled away his fortune, and Ohanyan, a 59-year-old scientist at the Yerevan Institute of Physics, had arranged to meet their buyer in a hotel in the Georgian capital on 11 March. They thought they were selling their 18g sample to a representative of an Islamist group as a precursor to a bigger consignment. But the buyer was an undercover police officer.
It is the third time in seven years HEU has been intercepted in Georgia. There have been 21 seizures or attempted thefts of weapons-grade material, uranium or plutonium, in the region since the Soviet Union collapsed. In every case the material seized had not been missed and mostly the theft was by an insider.
