Question

Write any two uses of actinides.

Answer 1

Uses of actinides:

1. 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.
2. Th(IV) oxide, ThO2 with 1% CeO₂ 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.
