dirty bombs, as in the non-nuclear form, is simple: you take any type of potently radioactive material and some explosives, like C-4, and load them into a bookbag, a truck, anything, then go VERY far away and denote the explosives. the blast wave propels the radioactive material in a large dust cloud, and the dirty bomb has done its toll.
A dirty nuclear bomb is detonated by using a conventional explosive. It disperses a large amount of nuclear material across the area.
The first atomic bomb detonated was not dropped, it was hung from the top of a steel structure and detonated remotely.
USSR
It is not , if it is not detonated and it is properly maintained.
I assume you mean "Soviet bomb" - The Tsar Bomba (Царь-бомба) was detonated on October 30, 1961, in the Novaya Zemlya archipelago. It was the largest, most powerful nuclear weapon ever detonated.
The Tsar Bomba, the largest nuclear bomb ever detonated, was tested by the Soviet Union on October 30, 1961. It had a yield of approximately 50 megatons and was detonated above the Arctic Circle.
It was dropped over Hiroshima.

The 50 Megaton "Tsar Bomba" hydrogen bomb tested by the USSR in 1961 is the strongest hydrogen bomb ever detonated. The 10 Megaton "Ivy Mike" hydrogen bomb tested by the U.S. in 1952 is the physically largest hydrogen bomb ever detonated.
Yes, the first was detonated by the U.S. in 1952.Codename Mike as part of Operation Ivy, it had a yield of 10.4 megatons(450 times as powerful as the bomb dropped on Nagasaki)and was detonated at Eniwetok atoll in the Marshall islands.
The detonation of the bomb seemed fast approaching and inevitable.
None, the airplane had already been far away when the bomb detonated.
