  1. I was wondering what use RadioCarbon dating C-14 has a half-life of 5730 years, is for Recent samples of maybe under 50 years.
    Since the report above had a Name of the testing service, I found that according to them
    Beta Analytic does not report standard deviations of less than +/- 30 BP for single measurements since this can lead to a misinterpretation of the accuracy of the results.
