Monazite sample contains 9% `ThO""_(2)` and 0.35% `U""_(3)O""_(8).Pb""^(208)` and `Pb""^(206)` are the stable and products in the radioactive decay series of `Th""^(232)` and `U""^(238)` respectively. All the lead in mozaite is of radiogenic origin. The isotopic ratio of `Pb""^(208)/Th""^(232)` was found to be 0.104. The half lives of Th and U are `1.41xx10""^(16)` years and `4.47xx10""^(9)` years respectively. Select the information incorrect about `Th""^(232)`A. It belonges to third group of actinide deriesB. `Th""^(232)` is a fissile materialC. It is a fissile matrialD. It belonges to 4n series |
