Today, the use of radioactive elements and materials in various fields such as medicine, industry, energy production and many other fields is inevitable. Environmental pollution which has dangerous for living organisms and ecosystems is a very important problem in this area. Therefore, it is very important to provide methods or use of materials that could be effective in reducing these pollutions.

Natural zeolites could be successfully used in this area due to their high cation exchange capacity and tendency to absorb some radioactive elements, high specific surface area, high thermal, mechanical and chemical stability, as well as their reasonable price and environmentally friendly nature.
