Uranium ores contain one radium-226 atom for every 2.8 * 10^6 uranium-238 atoms. Calculate the half-life of 92U238, given that the half-life of 88Ra226 is 1600 years (88Ra226 is a decay product of 92U238). given that the half-life of 88Ra226 is 1600 years (88Ra226 is a decay product of 92U238). Uranium ores contain one radium-226 [...]
