A method for producing a granulated inorganic adsorbent for a radionuclide is provided. SOLUTION: Slurry formation step 1 in which dihydrogen phosphate salt, powdered inorganic adsorbent raw material and coagulation modifier are kneaded in water to form a slurry, pulverized magnesium oxide is added to the slurry, kneaded and solidified Solidified slurry forming step 2 for forming a slurry, the solidified slurry is placed in a tray, dried and cured in a specific temperature range and dried to be cured to form a cured solid material, step 3 for crushing the cured solid material, and using a sieve mesh And granulating step 4 to obtain a radionuclide granulated inorganic adsorbent containing residual drug, and washing with water to remove the residual drug by washing the radionuclide granulated inorganic adsorbent containing residual drug. And a water washing step 5 to complete the manufacture. [Selection] Figure 1 |
