Carbon-14 is an isotope of carbon that is formed when radiation from the sun strikes
ordinary carbon dioxide in the atmosphere. Plants such as trees, which get their carbon
dioxide from the atmosphere, therefore contain a small amount of carbon-14. Once a
particular part of a plant has been formed, no more new carbon 14 is taken in. The carbon
14 in that part of the plant decays slowly.
Let P be the percent of carbon-14 remaining in a part of a tree that grew t years ago (so t
years ago, there was 100 percent of the carbon-14 existing in that part of the tree).
Write the particular equation expressing P in terms of t. You may assume that the half-life
of carbon-14 is 5730 years.
a.)
A piece of wood some believe to have come from Noah's Ark has 47.93% of its carbon-14
remaining. The Great Flood was supposed to have occurred in 4004 B.C. Is this piece of
wood old enough to have come from Noah's Ark? Justify your answer.
b.)
The half-life of phosphorus-32 is about 14days. There are 6.6 grams present initially.a. Express the amount of phosphorus-32 remaining as a function of time t.b. When will there be 1 gram remaining?
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?

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.
