International Isotope Society

The International Isotope Society (ITIS) is a global professional organization dedicated to promoting the understanding and use of isotopes—atoms of the same element with different masses—across scientific disciplines. It connects researchers, industry professionals, and institutions to share knowledge, advances research, and foster collaboration in areas such as healthcare, environmental studies, and energy. Through conferences, publications, and educational programs, ITIS helps advance the science of isotopes and their applications, supporting innovation and informed decision-making worldwide.
