There are 3 problems for measuring decay rates (& therefore "dating: the age of something)
1) The rates of radioactive decay and half-lives may not have remained constant over time. Past conditions could have seriously influenced the decay rates.
2) The assumption that the "clock" was set at zero could be wrong.
3) The assumption that we are dealing with a closed sysytem could be wrong. What if there was a loss of either parent or daughter isotopes being studied.
