Thorium vs Uranium Nuclear Power

Thorium 232, which alone makes up nearly all natural thorium, is the most common isotope of thorium in the nature.This isotope has the longest half-life (1.4 x 10 10 years) of all isotopes with more than 83 protons. In fact, its half-life is considerably longer than the age of earth. Therefore 232 Th belongs to primordial nuclides.. 232 Th decays via alpha decay into 228 Ra .

Occurrence of thorium Wikipedia

Thorium is found in small amounts in most rocks and soils.Soil commonly contains an average of around 6 parts per million (ppm) of thorium. Thorium occurs in several minerals including thorite (ThSiO 4), thorianite (ThO 2 + UO 2) and monazite.Thorianite is a rare mineral and may contain up to about 12% thorium

Composition of hydroponic medium affects thorium uptake by

Aug 01, 2013· Highlights Thorium was preferentially accumulated in root system of the tobacco plants. In the presence of organic acids the increase of Th content was observed. The addition of polyamines resulted in decrease of thorium accumulation. The higher Put concentration resulted in the lower Th uptake in the roots. The absence of phosphate ions caused the large increase of Th uptake.
