Atmospheric testing of nuclear weapons during the 1950s and early 1960s doubled the concentration of carbon-14 atmosphere and created a pulse that labeled everything alive in the past 50 years as carbon moved up the food chain the variation in carbon-14 concentration in time is well-documented and. So in bomb pulse dating it is the amount of 14c in the atmosphere that is decreasing and not the amount of 14c in a dead organisms, as is the case in classical radiocarbon dating this decrease in atmospheric 14c can be measured in cells and tissues and has permitted scientists to determine the age of individual cells and of deceased people.
