Is hydrogen bomb dirty

Answer 1

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.

Answer 2

Yes, hydrogen bombs can be considered dirty because they produce a significant amount of radioactive fallout when they explode. This fallout can have long-lasting environmental and health impacts on the surrounding area.
