Radioactive particles are removed from waste or process water and encapsulated by a filtration process wherein the water is filtered through a filter medium composed of a thermoplastic organic polymer. The filter cake so obtained is dried and converted to a solid encapsulating medium by the application of heat and/or pressure. The filter medium comprises, at least partially, a thermoplastic polymer which is wettable by water but non-swelling in water and has a melting point of 100 DEG to 300 DEG C. |
