The decay product of tritium is

There are four radioactive decay series called thorium (4n) , uranium (4n + 2) actinium (4n + 3) and neptunium (4n + 1) series. Neptunium series is artificial while other three series are natural. The end productsd of each radioacitve decay series have stable nuclei. All natural decay series terminate at lead but neptunium or artificial series terminate at bismuth. The end products of uranium and actinium series are, respectively

A nucleus of uranium decays at rest into nuclei of thorium and helium. Then :

Radium being a member of the uranium series occurs in uranium ores. If the half lives of uranium and radium are respectively 4.5 xx 10^(9) and 1620 years calculate the (N_("radiun"))/(N_("Uranium")) in Uranium ore at equilibrium.

Deawing attention to the pitfalls of __________ solely on Uranium as a fuel for nuclear reactors, Indian scientists warned that Uranium will not last for long and thus research on Thorium as its _________ must be revived.
