Span classnews_dtfeb 17 2016spannbsp018332ive been poking about on the internet again as you do and found a whole load of stuff by creationists about the problems with carbon 14 radiometric dating specifically they report with some glee that coal has been found to contain measurable amounts of carbon14 which it should not of course because it is about 300 million.
Carbon14 dating can be used on objects ranging from a few hundred years old to 50000 years old heres an example of calculating carbon14 dating.
In fact due to fluctuations in the carbon amount in the atmosphere modern c14 dating needs to be correlated to dates determined by analysis of treering records dendrochronology here is a brief article about how and why radiocarbon dates must be.
carbon dating is based upon the decay of 14 c a radioactive isotope of carbon with a relatively long halflife 5700 years while 12 c is the most abundant carbon isotope there is a close to constant ratio of 12 c to 14 c in the environment and hence in the molecules cells and tissues of living organisms.
For example pieces of wood that date at about 6200 bc by treering counts date at only 5400 bc by regular c14 dating and 3900 bc by cooks creationist revision of c14 dating as we see in the article dating relative and absolute in.
For example say a fossil is found that has 35 carbon 14 compared to the living sample how old is the fossil we can use a formula for carbon 14 dating to find the answer where t 12 is the halflife of the isotope carbon 14 t is the age of the fossil or the date of death and ln is the natural logarithm function if the fossil has 35.

Radiocarbon dating also referred to as carbon dating or carbon14 dating is a method for determining the age of an object containing organic material by using the properties of radiocarbon a radioactive isotope of carbon the method was developed in the late 1940s by willard libby who received the nobel prize in chemistry for his work in 1960.
