The radioisotope 204TI is produced via neutron activation of stable thallium in a nuclear reactor. 204TI isotope is found to have a half-life of 3.78 years. In the product-mixture of a nuclear reactor, a sample of 204TI with activity of 1.56 x 103 dps was isolated and kept in a sealed container. Work out the decay constant and estimate the activity after the container has been stored for 2 years and 3 months. Marking rubrics: (i) calculate the decay constant correctly - 1.5 point, (ii) calculate the activity correctly - 1.5 point.
