## Radiometric Dating

is second only to charcoal as a material chosen for radiocarbon dating. this method will tell you the years in which the radiocarbon concentration of tree rings is within two standard deviations of your measurement (e.., the activity of the sample, the standards, and the background, when establishing the 1-sigma limits. samples reported as "modern" have levels of radioactivity that are indistinguishable from modern standards such as oxalic acid.

due to contamination from bomb testing, some samples are even more radioactive than the modern standards. here's how:Based on one standard deviation of 120 years:1000 + 120 = 1120 bc (oldest date) 1000 - 120 = 880 bc (most. indeed, it was believed, apparently by analogy with elemental charcoal, that bone was suitable for radiocarbon dating "when heavily charred" (rainey and ralph, 1959: 366). that difference of 10 parts per mil from the oak standard means that the age of the marine mammal bone can be normalized by adding 160 years to its measured age.
