Draft talk:Radiocarbon dating/Introduction

Recent complications fossile fuels and bombs

 * 1) Two effects have complicated the use of radiocarbon dating for samples less than a few hundred years old. Fossil fuels contain almost no 14C, and the release of carbon arising from burning these fuels has decreased the fraction of C14 in the atmosphere in the past few hundred years.
 * 2) Approximately little or no 14 C was present in the 19th century. Howver, in 1965 C14 in the atmosphere doubled due to nuclear testing.
 * 3) Most fossil fuel contain no 14C due to the increased time it takes to decay. The concentration of 14C in the atmospehre has significant incereased in the past 200 years because of the ways of life demonstrated in humans.
 * 4) The booming fossil fuel industry lead to diluting 14 C in the atomsphere, however nuclear testing doubled the 14 C in 1960's.
