Abstract:
The invention provides a method for producing a solution containing 211At− (astatide ion) at a high radiochemical purity by using 211At obtained by a nuclear reaction as a starting material, including a step of adding a reducing agent to a solution containing an impurity derived from 211At. The invention also provides a solution containing 211At− (astatide ion) at a radiochemical purity of not less than 30%.
