For organic objects of intermediate ages—between a few centuries and several millennia—an age could be estimated by measuring the amount of carbon present in the sample and comparing this against the known half-life of carbon From the measurement performed in the Dead Sea Scrolls were determined to be years old giving them a date of 53 BC, and confirming their authenticity. There are two types of testing technology: Carbon is distributed throughout the atmosphere, the biosphere, and the oceans; these are referred to collectively as the carbon exchange reservoir, [32] and each component is also referred to individually as a carbon exchange reservoir.
