[Dune] When shields get him by a lasgun beam and create a nuclear detonation, how big of an explosion are we talking? Does a single person's body shield blow up in a small area like Fallout's Fat Man launcher, or is a city-sized mushroom cloud like Hiroshima?

Completely random.

It could be highly localized and just vaporize those who triggered the effect, or it could cause an atomic explosion that level cities.

The unpredictability is why it is not really used by anyone, either as small scale bomb or as atomic weapons.
