Even outside of combat this Semblance is worthless. Remnant has no interest in harnessing the power of the atom for peaceful power or punishing purges. The only case where this could be useful outside of a fanfic that makes things up to suit the author (not a logical, good narrative) or makes huge leaps in logic and/or event progression, would be stumbling across raw nuclear material that had been uncovered as a byproduct of looking/mining for Dust or combat.

Even then the poor sap might not even realize what they can do here, and suffer (minor-medium) lingering health problems. Given how few people seem to actually understand radiation and basic nuclear science IRL, I doubt some random person in Remnant would have any useful knowledge for this Semblance, let alone find frequent, if any, opportunities to use it.

Remnant's technology is fundamentally based on Dust. Researching nuclear power would seem needlessly dangerous and expensive. Why bother trying to harness the ore that would be seen as harmful geological filler when you could pick up some crystals topower your home, run a sauna, and torch anything that looks at you funny.

When their attempts at space exploration failed due to Dust losing power upon leaving Remnant's atmosphere, they gave up. They didn't try any sort of alternative that meant leaving the atmosphere beacause that is how much they rely on Dust.
