Document Title: Ultrapure Yttrium-90
Category: Health-Related Research and Technologies
Media Type: Photos
Date of Image/Photo: 1991
Background: Previous techniques left traces of strontium-90 and metal contaminants, which hampered effective treatment using yttrium. The process removes those contaminants to generate an exceptionally high-quality radioisotope.
