For instance, the amount varies according to how many cosmic rays reach Earth. In we could only calibrate radiocarbon dates until 26, years. Sedimentary rocks can be dated using radioactive carbon, but because carbon decays relatively quickly, this only works for rocks younger than about 50 thousand years.
