The 1/2 life of Weapons Grade Plutonium is 24,100 Years. Therefore once you bomb this stuff it will keep killing for at least 24,100 years throughout the middle east:

I think my question would be here: "Would this also eventually drift across the Mediterranean ocean and kill people eventually in Europe too? The answer likely would be: "Within 24,100 years this stuff could literally in the form of radioactive Dust could encircle the planet killing sporadically people everywhere over time. It only takes a few radioactive particles in your lungs to kill a person (like it did John Wayne) from making a movie too close to an old A-Bomb testing site in the U.S. Many other people in this movie also died from radiation poisoning from breathing in a few radiated particles eventually too caused by the A Bomb explosion and it's aftermath. However, the bomb went off possibly 10 to 20 years before and killed that much later. 

 begin quote from Google AI:

The primary isotope in weapons-grade plutonium is plutonium-239, which has a half-life of approximately 24,100 years. This means it takes about 24,100 years for half of the plutonium-239 atoms to decay into other elements. While plutonium-239 is the most common, weapons-grade plutonium also contains other isotopes like plutonium-240, which has a half-life of about 6,560 years.
