It is also demonstrated that data on violation in the isotopic equilibrium of the thorium content in various media can be used to assess the pathways of thorium release into the environment. It is noted that the spatial patterns of thorium concentrations are rather close in the soil and bottom...
Assessment of Thorium in the Environment (A Review) The calculated potential energy surfaces, V ([beta], [gamma]), forthorium seriesof isotopes are presented in Fig. IBA-1 model has been used in calculating the energy of the positive and negative parity low -lying levels ofthorium seriesof...
In the environment, thorium exists in combination with other minerals, such as silica. Small amounts of thorium are present in all rocks, soil, water, plants, and animals. Soil contains an average of about 6 parts of thorium per million parts of soil. More than 99% of natural thorium ...

In organisms. Thorium is always present in the tissues of plants and animals. The element’s coefficient of accumulation, that is, the ratio of its concentration in the organism to the concentration in the environment, is 1,250 in marine plankton, 10 in benthic algae, 50–300 in the soft...

Waste products such as mill tailings produced from mining and refining activities may result in the contamination of the water and the environment. While we have a greater understanding of the contamination of the environment due to uranium mining waste, very little is known of the impacts of Th...
