WebApr 10, 2024 · Latest Survey on "Nuclear Medicine Radioisotope Market" Report 2024, With 118 Pages, Forecast 2029 Published: April 10, 2024 at 11:43 p.m. ET Thorium (90Th) has seven naturally occurring isotopes but none are stable. One isotope, Th, is relatively stable, with a half-life of 1.405×10 years, considerably longer than the age of the Earth, and even slightly longer than the generally accepted age of the universe. This isotope makes up nearly all natural thorium, so thorium was considered to be mononuclidic. However, in 2013, IUPAC reclassified thorium as binuclidic, due to large amounts of Th in deep seawater. Thorium has a c…
