Transuranium elements and isotopes are used in medicine [Figure2]

  • Seaborg synthesized 10 transuranium elements and lots of isotopes, which we use now in medicine, industry and the nuclear power industry.
  • Seaborg was the first living person to have an element named for him: 106 Seaborgium.
  • Seaborg was an important asset to the United States during World War II and after.
