<\/div>D<\/span>uring the 1950s and early 1960s, atmospheric <\/span>nuclear testing<\/b> sharply increased the concentration of <\/span>carbon-14<\/b> in the air. This excess radiocarbon was later absorbed by oceans, plants and food, eventually entering the human body.<\/span><\/p>\n
Carbon-14 as a biological clock<\/strong><\/h5>\n

The resulting atmospheric curve, known as the <\/span>bomb pulse<\/b>, became an unexpected <\/span>biological clock<\/b>. By measuring tiny amounts of carbon-14 in DNA, scientists can estimate when certain cells were formed and investigate how long they remain in our bodies.<\/span><\/p>\n
