ANS is celebrating Actinide Days by giving some exceptional radioisotopes the credit they deserve on social media, and today it’s double the fun, with both plutonium-238 and uranium-238 getting a turn in the spotlight. While the actinides may be buried in the bottom row of the periodic table, isotopes of these elements are hard at work in applications in medicine, industry, power, and space. Visit ANS on Facebook, Instagram, and Twitter to join the conversation and speak up for your favorite actinides.
