This area is seriously contaminated with radioactive isotopes.

Nuclear fusion is expected to be a future energy source.

In this chemical reaction, a specific isotope is produced.

Nuclear reactions are used for mass production of energy.

Tritium is a radioactive isotope, mainly produced in nuclear fusion reactions.

This rock is radioactive, so care must be taken when handling it.

His body is very healthy.

We formed a team to create a new project.

This software generates new ideas.

The development of fusion reactors could potentially be the key to solving future energy problems.
