Answer:
Radioactive
Step-by-step explanation:
The daughter products of fission reactions are radioactive and can be a hazard.
A fission reaction is a method of splitting large particles into smaller ones, for example, splitting of the atom. Fission reaction can either be a nuclear reaction or a radioactive decay process. The effect of fission is the absorption or release of energy. Radioactive decay is the method by which an unbalanced atomic nucleus loses energy by heat.
