溶液の製造方法。(1) A stirring tank is housed in the extraction tank, and ore containing radioactive substances such as thoron and radon is granulated between the mesh-like filter plates installed on the upper and lower sides of the stirring tank. At the same time, an acidic hot aqueous solution for extraction is injected into the extraction tank to the extent that at least the stirring tank is buried, and a liquid layer is formed at the bottom of the extraction tank and a gas layer is formed at the top. , providing a first circulation flow path that communicates between the bottom side of the lower filter of the stirring tank and the gas layer through a pipe line and pressure-feeding the gas in the gas layer with a pump and injecting it into the stirring tank; The granular ore is stirred between the filters by a jet of the hot aqueous extraction solution generated in the stirring tank, and when the jet passes through the lower filter, the bubbles that are generated rise and rupture to form the granules. Ultrasonic microvibration is applied to the shaped ore to accelerate the decay of the radioactive materials contained in the ore, and the radioactive decay products are extracted into a gaseous state, and a portion of it is directly stored at the extraction temperature in the extraction tank. Most of the remaining water melted in the aqueous solution flows into the gas layer, and a pipe is connected between the liquid layer and the gas layer to transfer the hot aqueous solution for extraction in the liquid layer into the gas layer. A second circulation flow path is provided in which the gaseous radioactive decay products that have flowed into the gas layer are liquefied and melted into the hot aqueous solution for extraction.
