After a brief review of the basics of 14c bomb-pulse dating, this paper presents two unique forensic applications particular attention is dedicated to the use of the 14c bomb-pulse to establish. Nuclear bombs made it possible to carbon date human tissue actually have a memory of the bomb pulse,” says lead to make use of this unique form of carbon dating for a few more decades. Forensic experts use radiocarbon dating to establish if an individual died recently (perhaps a matter for the justice department) or in antiquity (a matter for the archaeologist) they do this by using the “ bomb carbon ” curve.
Carbon-14, 14 c, or radiocarbon, is a radioactive isotope of carbon with an atomic nucleus containing 6 protons and 8 neutrons its presence in organic materials is the basis of the radiocarbon dating method pioneered by willard libby and colleagues (1949) to date archaeological, geological and hydrogeological samples.

Bomb-pulse dating relies on precise measurements of the declining 14c concentration in atmospheric carbon dioxide collected at clean-air sites however, local variations in the 14c specific activity of air and foodstuffs occur, which are caused by natural processes as well as by various human activities. When scientists want to find out how old a fossil is, they often look at the amount of carbon 14 it contains this radioactive isotope was present in the atmosphere in a steady ratio with its more stable counterpart, carbon 12, for a long time.
Radiocarbon dating, with special reference to the modern bomb-curve, can provide useful information to elucidate the date of death of skeletonized human remains. When scientists want to find out how old a fossil is, they often look at the amount of carbon 14 it contains this radioactive isotope was present in the atmosphere in a steady ratio with its more stable counterpart, carbon 12, for a long time scientists can cross-check this ratio with knowledge of the half-life of carbon 14 to determine the era a given fossil comes from. The bomb pulse is the sudden increase of carbon-14 (14 c) so in bomb pulse dating it is the amount of 14 c in the atmosphere that is decreasing and not the amount of 14 c in a dead organisms, as is the case in classical radiocarbon dating.
A pulse of radioactive carbon released by nuclear bomb testing stamped a date on every living cell, giving scientists the opportunity of a lifetime.

14 c “bomb pulse” pulse forensics 14 c “bomb pulse” dating as a forensics tool traditionally, radiocarbon dating has been considered to be an archeological tool rather than a forensic one radiocarbon or carbon-14 (14 c) is produced naturally in the atmosphere by cosmic ray interactions with nitrogen. Request pdf on researchgate | bomb‐pulse dating | atmospheric testing of nuclear weapons during the 1950s and early 1960s doubled the concentration of carbon-14 atmosphere and created a pulse.
