Nuclear disintegration and carbon dating. a) The rate of decay of a radioactive nuclide is proportional to the number of nuclei N present at time t, where the proportionality constant is given by the decay constant λ: dN dt = −λN Derive an expression for the number of nuclei as a function of time N, using N0 as the number of nuclei that are present initially (at t = 0). b) Derive the relationship between the half-life T1/2 and the decay constant λ. c) A piece of wood from an ancient sunken ship has a specific activity of 100 Bq/kg due to 14C. A sample of comparable living wood has an activity of 270 Bq/kg. Using the carbon dating method, determine the age of the ancient piece of wood, given that the half-life of 14C is 5730 years.

Which type of nuclear decay is the following radioactive isotope likely to undergo? All known stable isotopes are shown on the graph. The points form what is know as the "belt of stability". If a radioactive isotope is above the belt of stability, think about what type of decay would decrease its N/Z ratio. If an unstable isotope is below the belt of stability, think about what type of decay would increase its N/Z ratio. If a radioactive isotope is...
