Technetium (Tc) is a by-product of the spontaneous fission of Uranium-238 and as such is of particular interest to the nuclear sector. The most common isotope is 99Tc which is unstable and decays by emission of a beta particle, with a half-life of t½ = 2.11 x 105 years. A 99Tc sample is characterised and is found to contain 0.1 mol of the radionuclide. Determine the time required for the amount of technetium to reduce by 1% of this value
