Write two applications of actinoids.

Answer
- The half-lives of natural thorium and uranium isotopes are so long that we get very negligible radiation from these elements. So, we find them in everyday use.
- Th(IV) $oxide$, $ThO_2$ with $1 \%$ $CeO_2$ was used as a major source of indoor lighting before incandescent lamps came into existence only because these oxides convert heat energy from burning natural gas to intense light. Even today, there is a great demand for these lights for outdoor camping.
