Thorium waste half life
WebThe radioactivity of thorium was found independently (1898) by German chemist Gerhard Carl Schmidt and by French physicist Marie Curie. Natural thorium is a mixture of … WebWith a half-life of 77,500 years, thorium-230 makes up more than 80% of the measured radioactivity in soil at West Lake above cleanup limits set by the Department of Energy (DOE) (see Figure 5). Moreover, as the thorium-230 decays to radium-226, it will increase the radioactivity in the landfill 10 to 100 times over a 9,100 year period.
