The method was developed by Willard Libby in the late 1940s and soon became a standard tool for archaeologists.Libby received the Nobel Prize in Chemistry for his work in 1960. uncalibrated, radiocarbon ages are usually reported in radiocarbon years "Before Present" (BP), "Present" being defined as AD 1950.Such raw ages can be calibrated to give calendar dates.

There are also trace amounts of the unstable radioisotope carbon-14 (14C) on Earth.

The older a sample is, the less (the period of time after which half of a given sample will have decayed) is about 5,730 years, the oldest dates that can be reliably measured by this process date to around 50,000 years ago, although special preparation methods occasionally permit accurate analysis of older samples.

The idea behind radiocarbon dating is straightforward, but years of work were required to develop the technique to the point where accurate dates could be obtained.

Carbon is naturally in all living organisms and is replenished in the tissues by eating other organisms or by breathing air that contains carbon.

At any particular time all living organisms have approximately the same ratio of carbon 12 to carbon 14 in their tissues.

In 1960, he was awarded the Nobel Prize in chemistry for this work.

  1. I'm assuming you're using DB2 for z/OS, which unfortunately (for whatever reason, I never really understood why) doesn't support using a values-list where a full-select would be appropriate. It's a little unwieldy, but it works: INSERT INTO table Name (col1, col2, col3, col4, col5) SELECT val1, val2, val3, val4, val5 FROM SYSIBM.
