1. Radon generator in the form of a cylindrical body closed at both ends, equipped with filters and containing radon carrier in between the filters, the body being connected to gas valves, characterized in that as the radon carrier it contains polyurethane foam (1) and that the internal walls of the body (2) are optionally coated with a layer of glue (3).2. A method of radon carrier synthesis by means of polyaddition of aromatic diisocyanates to polyethers in the presence of silicone preparations, amine and organic tin catalysts and water, characterized in that an activating mixture is made as a solution of silicone oil, tri-ethyleno-diamine and organic tin catalyst in toluene, and this solution is added to polyester resin and a solution of radium chloride in hydrochloric acid is added to the obtained mixture.<IMAGE>
