Subsequently, these dates were criticized on the grounds that before the scrolls were tested, they had been treated with modern castor oil in order to make the writing easier to read; it was argued that failure to remove the castor oil sufficiently would have caused the dates to be too young. Volcanic eruptions eject large amounts of carbon into the air. Libby and his team of scientists were able to publish a paper summarizing the first detection of radiocarbon in an organic sample. Carbon 14 hast a half life of 5, years which means that after that number of year half of the carbon 14 atoms have decayed into netrogen 14 it is the ratio of carbon 14 to nitrogen 14 in that substance that indicates the age of substen Ce.
