If a cell is damaged by radiation, there are five ways it can go.
Cell repairs itself, divides into healthy daughter cells.
Mutated cell divides into mutant daughter cells that live.
Mutated cell divides into mutant daughter cells that die.
Reproductive death. Cell functions. No longer divides.
You left off “Cell vaporizes”.
If you're in a radiation field that strong, you won't need to worry about long-term health effects.
And technically, vaporization is covered under cell death.
