Resumen:	Phosphogypsum (PG) is a hazardous waste associated with the phosphoric acid production using the wet process. PG is considered a relatively high level natural uranium series radionuclide material, which provokes a negative environmental impact and many restrictions on the use of the PG waste (only 15% of the PG generated is recycled in agriculture, in gypsum board and cement industries). The US-EPA has classified PG as Technologically Enhanced Naturally Occurring Radioactive Material (TENORM). Legislations and standard regulations have established maximum limits for PG radionuclides concentration and exposure.
