A mutation in a plant that could cause negative outcomes could be the plant has less leaves, or isn't hardy enough, like other plants. It would die. A plant from an area like Chernobyl, that has been affected by radiation could poison other animals, or pass that gene along, and ultimately kill that strand of plant.
The stabilization of a radioactive parent element into a stable daughter element occurs through the process of radioactive decay. The unstable atomic parent emits radiation and loses its energy. This leads to the formation of a daughter element, which is less radioactive or is stable.
