Rafter radiocarbon dating

When radiation penetrates the cylinder it starts an electric rafter between the anode and the cathode which can be detected electronically as an electric pulse. The process of converting a conventional radiocarbon age to a "true" or calendar age. It is important to note that the CRA is calculated from a dating of an isotopic ratio, ie radiocarbon dating does not measure time directly.
