The article reviews the project of radiation safety management for the short-lived alpha nuclides, 211At, 223Ra and 225Ac. 211At is dispersed to a certain extent from an aqueous solution and the dispersal rate decreases when the cap is put on the vessel. The small amount of 219Ra is dispersed in use of 223Ra. The dispersal rate decreases with decreasing exposed surface area of the solution to the air. The dispersal rates of 225Ac and the descendant nuclides are quite small. The project to develop a guideline and instruction material for radiation safety management of short-lived radionuclides was started from 2019. The work is in progress.
