I think that it generally means that something is superior, of great quality, or is greatly enjoyed by a person.
If you mean "atomic" as in the Atomic Bomb, then the word "nuclear" could be substituted = Nuclear Bomb.
A nuclear bomb is any bomb with any nuclear or atomic material inside it, while a plutonium bomb is a specific type of nuclear bomb. Plutonium could be the nuclear material inside the bomb, and if it is, it's a plutonium bomb.
We'll consider "dirty" to mean producing radioactive fallout. Since hydrogen bombs (fusion bomb) require the energy from an atomic bomb (fission bomb) they are a little dirty. Its mostly the atomic bomb that creates dangerous isotopes that contaminate the blast area, and regions down-wind. Now an H-bomb is generally "cleaner" than a bomb purposefully-design to create a large amount of dangerous, radioactive fallout. There are various techniques where one can change the type and duration of fallout. These types of weapons are generally use fission (not fusion) to create this effect.
A hydrogen or fusion bomb will be ten times more powerful than the original fission atomic bomb.
A francium bomb cannot exist.
