The curie (Ci) is a commonly used unit for measuring nuclear radioactivity: 1 curie of radiation is equal to 3.7 × 100 decay events per second (the number of decay events from 1 g radium in 1 s). A 1.7-mL sample of water containing tritium was injected into a 170-lb person. The total activity of radiation injected was 86.5 mCi. After some time to allow the tritium activity to equally distribute throughout the body, a sample of blood plasma containing 2.0 mL water at an activity of 3.6 µCi was removed. From these data, calculate the mass percent of water in this 170-lb person. Neglect the radioactivity change of the sample during experiment time Mass percent =

When any radioactive dating method is used, experimental error in the measurement of the sample's activity leads to error in the estimated age. In an application of the radiocarbon dating technique to certain fossils, an activity of 0.130 Bq per gram of carbon is measured to within an accuracy of 14.0 percent. Find (a) the age of the fossils and (b) the maximum error (both in years) in the value obtained. Assume that there is no error in the 5730-year half-life of 6C¹4 nor in the value of 0.23 Bq per gram of carbon in a living organism. (a) Number i (b) Number i Units Units
