Radiocarbon dating 101
Since tree rings provide an annual calendar, and some trees live for thousands of years, by C-14 dating the rings themselves one could correct the radiocarbon dates and calibrate the differences. should refer to the year the method was recognized, 1950.
The Bristlecone pine trees in the Sierra Nevada mountains made this possible and today there are international tree ring databases and agreed-upon calibration curves.
The C-14 method cannot be used on material more than about 50,000 years old because of this short half-life.
Other isotopes are used by geologists to date older material.
" In BAR, we summarized the controversy that has enshrouded this relic, venerated for centuries as the burial cloth of Jesus ("Remains to Be Seen," Strata, Julyl August 1998, p 13).
The most characteristic form of acheiropoietos, however, is the holy cloth. Veronica stepped forward to wipe the sweat from Jesus' brow as he stumbled toward Calvary, and her towel already transformed into a relic through that holy contact miraculously retained the image of Jesus' face.

Each radiocarbon date has a statistical probability shown by the ± number.
This number is called a standard deviation and is a measure of the spread of measurements around the mean (average).
