The squee-CHUNK, squee-CHUNK of the vacuum pump forces everyone in the cavernous room to yell.Physicist Bruce Buchholz peers at an aluminum container the size of a black bean.Pauling continued delivering these speeches for a number of years, until it appeared that his career in activism might wind down due to the great time demands required by his ambitious program of protein research.However, after the US detonated the first hydrogen bomb in 1954 and the term “fallout” started to become more commonplace, Pauling’s vigor as an activist returned.Because of its inherently chemical nature, Pauling quickly became somewhat of a fallout expert, and in 1958 he wrote a paper about the dangers of carbon-14, a topic that had not been discussed at great length.Carbon-14 is a radioactive isotope of carbon that is not prevalent in nature – it comprises roughly one part per trillion of all the carbon in the atmosphere – but is a byproduct of nuclear explosions.Using this information, Pauling calculated that, at 1958 population levels, one year of bomb testing would therefore produce enough carbon-14 to lead to “12,000 children with gross physical or mental defect, 38,000 stillbirths and childhood deaths, and 90,000 embryonic and neonatal deaths.” Although these numbers are very small when compared to the total 1958 world population of just under three billion, they still are suggestive of a significantly dangerous side-effect from nuclear weapons testing.Furthermore, Pauling accounted for the fact that, as the population continued to grow, the number of people exposed to carbon-14 would also increase.

Little did we know that the bomb didn’t just scar our psyches. Hundreds of atmospheric bomb tests before 1963 doubled the amount of radioactive carbon in the air.The clue lies inside the tooth, in an unsettling imprint made by atomic bombs.In the decades after World War II, generations of schoolchildren practiced “duck and cover” drills, scrambling under their desks against the grim possibility of nuclear attack.Although it may not present a significant short-term effect, radioactive carbon that is incorporated into the body will remain there and emit radiation for as long as the organism exists, thus increasing the possibility of health problems both for the affected body as well as its offspring.From Libby’s data, Pauling determined that at the rate that bombs were being tested circa 1958 – which Pauling calculated to be 30 megatons worth of explosions – 74 kg of carbon-14 were released per year.
