What is the difference between carbon dating and thermoluminescence Free sexy chat with hot man
In the example below, the bone must date to sometime between 1.75 and 1.5 million years ago.
Most mineral materials, including the constituents of pottery, have the property of thermoluminescence (TL), where part of the energy from radioactive decay in and around the mineral is stored (in the form of trapped electrons) and later released as light upon strong heating (as the electrons are detrapped and combine with lattice ions).
Such contamination can occur if a sample is exposed to carbon compounds in exhaust gasses produced by.
In addition, any argon that existed prior to the last time the rock was molten will have been driven off by the intense heat.
Following death, however, no new carbon is consumed.
Progressively through time, the carbon-14 atoms decay and once again become nitrogen-14.
The atoms of crystalline solids, such as pottery and rock, can be altered by this radiation.
