Putting it all together! Radioisotopes are often used in diagnostic imaging for detecting disease. The isotope 64Cu (copper-64), which has a half-life of 12.7 hours, is used to study diseases affecting copper metabolism such as Wilson's disease. What percentage of the original activity in the sample remains after 38.0 hours? Show your work, include units, and pay attention to significant figures. Hint: Remember that this process follows first order kinetics and 0.693 t1/2 that half-life is given by: k =
