The activity of a radioisotope changes with:

When nuclear energy is intended to be harnessed for the generation of electricity,the potentially destructive neutrons released in a nuclear reactor are absorbed by:

In the Thorium series,$_{90}Th^{232}$ loses a total of $6$ $\alpha$-particles and $4$ $\beta$-particles in ten stages. The final isotope produced in the series is

The energy required to separate a neutron and a proton from the nucleus is called:
