Abstract  

A rapid method for the production of115mIn from irradiated cadmium is described. The procedure of the method is based on the extraction of115mIn by bis(2-ethyl hexyl) phosphoric acid (HDEHP) from 0.1N sulphuric acid. Accumulated115mIn can then be reextracted into diluted hydrochloric, hydrobromic, nitric or sulphuric acid solutions with a concentration of 1N or higher. A summary on the behaviour of cadmium and indium extraction with the solvent was given as a preliminary step in the present study. The produced115mIn was found to be free from any cadmium as well as from any other foreign activity.
