:The rate of decay of 14C is such that 50% of the 14C in the sample will decay in 5730 years ... For this reason, scientists do not generally attempt to carbon date material that is believed to be older than about 50,000-60,000 years old.--[[User:Aschlafly|Aschlafly]] 16:35, 21 January 2008 (EST) | :The rate of decay of 14C is such that 50% of the 14C in the sample will decay in 5730 years ...
