Bananas are rich in potassium and contain the naturally occurring potassium-40 radioisotope. Potassium-40 is a significant source of radioactivity in the human body and the activity of a human body due to potassium-40 is approximately 5400 Bq. Potassium-40 has a half-life of 1.25 x 10⁹ years and it is a beta-emitter. (i) Write the decay equation, including the atomic number and mass for each element when potassium-40 undergoes a beta emission. (3 marks) (6 marks) (ii) Calculate the number of potassium-40 nuclei in a person with an activity of 5400Bq.
