²²³Ra is one of the most promising -particle emitters for targeted radionuclide therapy. In this work, the possibility of producing ²²³Ra by neutron irradiation of ²²⁶Ra in Dhruva Reactor at Bhabha Atomic Research Centre, India has been studied.
A Bateman equation solver has been developed and used to calculate the activity yield of ²²⁷Ac for various combinations of irradiation and cooling periods. Based on this analysis, optimum time of irradiation and cooling have been estimated for
maximizing the activity of ²²⁷Ac while keeping the activity from other unwanted nuclides as small as reasonably possible.
