It is the beta decays, with some associated gamma rays, which make the fission products highly radioactive. This radioactivity (by definition!) decreases with time.

Web7 The mass spectrum of a sample of krypton taken from a meteorite is shown below. 7(a) Use this spectrum to calculate the relative atomic mass of this sample of krypton. Give your answer to one decimal place. Explain why the value you have calculated is slightly different from the relative atomic mass given in the Periodic Table. WebThe shortcomings of the krypton standard were demonstrated by the measurement of the wavelength of the light from a methane-stabilised helium–neon laser (λ ≈ 3.39 μm).
