Scientists Develop Inorganic Resins for Generating and Purifying Radium and Actinium

Wednesday, June 7, 2023 - 16:03 in Health & Medicine

Targeted alpha therapy using radioisotopes such as actinium-225 can destroy cancerous cells without harming healthy cells. However, making actinium-225 by bombarding radium targets with neutrons poses a challenge: how to chemically separate the radium from the actinium. A new approach uses radiation-resistant inorganic resin scaffolds as platforms for separating radium, actinium, and lead, improving production time, cost, and safety.
