A wooden artifact is burned and found to contain 21 g of carbon. The 14C activity of the sample is 190. disintegrations min. What is the age of the artifact? (Assume that t/2 for 14C is 5730 yr. The activity of 4C in the atmosphere (and therefore in all living things) today is 0.255 Bq'g of total carbon.) Age = years

A medical technician is working with the four samples of radionuclides listed in the table below. Initially, each sample contains 24.00 umol of the radionuclide. First, order the samples by decreasing initial radioactivity. Then calculate how long it will take for the amount of radionuclide in each sample to decrease to 1/3 of the initial amount. radionuclide time for amount of radionuclide to decrease to 1/32 of initial amount sample Initial symbol half-ife radioactivity 177 Lu 71 7.0 days tehnose one 0 O days 212 Bi O nours 1. hour (choose one) e 83 85 O days Sr 65.0 days (choosa one) B 38 88 107. days O days D.

You are an archaeologist, and send some leather clothing found at a burial site to be radiocarbon dated. Based on other clues, you think that the leather should be 2500 years old. What activity ought to come back from the lab, in Bq per gram of carbon? (These sorts of checks are important in science.) The base carbon-14 activity is 0.231 Bq per gram of carbon, and the decay constant of carbon-14 is 1.21x104 1/year.
