I’m sure that in 1985, plutonium is available in every corner drugstore, but in 1955, it’s a little hard to come by.

- Beirut (Wikipedia)
Beirut is the capital and largest city of Lebanon. As of 2014, Greater Beirut has a population of 2.5 million, which makes it the third-largest city in the Levant region. The city is situated on a peninsula at the midpoint of Lebanon’s Mediterranean coast. Beirut has been inhabited for more than 5,000 years, and was one of Phoenicia’s most prominent city states, making it one of the oldest cities in the world (see Berytus). The first historical mention of Beirut is found in the Amarna letters from the New Kingdom of Egypt, which date to the 14th century BC.
- Plutonium (Wikipedia)
Plutonium is a chemical element; it has symbol Pu and atomic number 94. It is a silvery-gray actinide metal that tarnishes when exposed to air, and forms a dull coating when oxidized. The element normally exhibits six allotropes and four oxidation states. It reacts with carbon, halogens, nitrogen, silicon, and hydrogen. When exposed to moist air, it forms oxides and hydrides that can expand the sample up to 70% in volume, which in turn flake off as a powder that is pyrophoric. It is radioactive and can accumulate in bones, which makes the handling of plutonium dangerous.
