One method for determining the age of ancient objects is by radiocarbon dating. Natural processes convert nitrogen to Carbon-14, a radioactive isotope with a half-life of 5730 years. When they are alive, animals assimilate Carbon-14 through the food chain. When an animal dies, it stops replacing its carbon and the amount of Carbon-14 decays exponentially. (a) Suppose the minimum detectable amount is 0.1% of the initial amount. What is the maximum age of a fossil that we could date using Carbon-14? (b) Suppose we wanted to date a fossil that was potentially 70 million years old. A radioactive isotope with what half-life would be required?
Phosphorus-32 is a commonly used radioactive nuclide in biochemical research, particularly in studies of nucleic acids. The half-life of phosphorus-32 is 14.3 days.

An accident at a nuclear power plant has left the surrounding area polluted with radioactive material that decays naturally. The initial amount of radioactive material present is 42 su (safe units), and 5 months later it is still 31 su. a.) write a formula giving the amount A(t) of radioactive material (in su) remaining after t months. (Use integers or decimals for any numbers in the expression. Round to three decimal places needed.) b.) what amount of radioactive material will remain after 11 months? c.) how long will it be until A = 1 su, so it is safe for people to return to the area?
Suppose you are working as a reactor operator in the world’s largest nuclear power station at Kashiwazaki-Kariwa Nuclear Power Plant, Japan. The first unit in this station began to operate in 1985. Suppose the rate at which the nuclear power plant produces radioactive waste is proportional to the number of years it has been operating such that 500 pounds of waste is produced every year. Also, suppose that the waste decays exponentially at a rate of 5% per year. At the beginning of 2011, The Fukushima Daiichi nuclear disaster caused sever damages in the units which released the radiation waste to the atmosphere. Therefore, all the units were closed in 2011 for safety inspection. This left japan completely without nuclear-produced electrical power. Finally, the unit began to operate at the beginning of 2019. As a reactor operator, you are asked to do the following: a. Model the generation of the Kashiwazaki-Kariwa Nuclear Power Plant radioactive waste as a function of time. b.…
