PROBLEM TO BE SOLVED: To provide a method for forming a coated base sheet which exhibits extremely low speed dissolution and releasing of a coated radioisotope and is suitable for use in medical applications. SOLUTION: A method for coating a base sheet with a radioisotope is provided. In this case, it consists of a process wherein the base sheet is immersed into a soln. contg. γ, β<+> , α or β<-> releasing radioisotope, a process wherein this base sheet is exposed to conditioning vibration cavitation to produce a coated base sheet, a process wherein the coated base sheet is calcined at a temp. below the recrystallization temp. of the base sheet, a process wherein the coated base sheet is rinsed and a process wherein the coated base sheet is dried. |
