While studying the properties of a sample of material obtained from an excavation site, you discover an isotope of element W, 176 W. 98 Element W undergoes a series of decays until eventually a stable isotope is reached. Write the equations for the following nuclear reactions: Element W decays to release a gamma ray, The daughter nuclei of the nuclear reaction stated in question 2) b) i) decay to release a beta particle, and The daughter nuclei of the nuclear reaction stated in question 2) b) ii) decay to release an alpha particle. At the time of discovery at the excavation site, a sample of the isotope had 543000 radioactive nuclides and a corresponding activity of 350 Bq. Calculate the half-life of the isotope. The sample is transported from the excavation site to the laboratory. On arrival to the laboratory, its activity is 120 Bq. Calculate The time taken to reach the laboratory, and The number of radioactive nuclides left on arrival at the laboratory.

Suppose that you want to find out how much gasoline is in an underground storage tank. You pour in 1 gallon of gasoline that contains some radioactive material with a long half-life that gives off 5000 counts per minute. The next day, you remove a gallon from the underground tank and measure its radioactivity to be 10 counts per minute. How much gasoline is in the tank?
