• Question 4

 

	How is C-14 created in our atmosphere?
	Answers: The photosynthetic process of plants produces C-14 as a by product.   C-14 is a industrial pollutant created by the combustion of fossil fuels.   Cosmic rays bombard our upper atmosphere and cause N-14 to transmutate (change) into C-14.   It is produced by the decay of C-15.

• Question 5

 

	What is the half-life of C-14 and what is its daughter element?
	Answers: About 1 hour, B-14   About 1.5 billion years, Pb-206   About 1 million years, C-13   About 5,700 years, N-14
