Sample of decaying materials
WebOne sample of rock is shown decaying and the level of decay is corresponded to points on a decay graph. The fraction of radioactive isotopes observed in the spectrometer will decrease exponentially in time, while the mass of decay products (like boron for carbon-10) … WebAfter another interval of 5.26 years, the sample would contain only 2 g of cobalt-60. Neither the volume nor the mass of the original sample visibly decreases, however, because the unstable cobalt-60 nuclei decay into stable nickel-60 nuclei, which remain with the still-undecayed cobalt.
