Luminescence dating laboratory
Then we need to correlate thermoluminescence light to radiation dose rate per year which the sample has received since its last clock resetting event.Eventually, we will follow this formula to found out how many years old the sample is: Age (year) = accumulated dose / dose rate per year Thermoluminescence dating can be performed only in a specialized laboratory which will have a chemical section for the treatment of the samples with reagents and a radiation hazard restricted area.Thermoluminescent Natural radioactivity causes the number of trapped electrons to build up.The older an object, the more trapped electrons it will have.
The intensity of the thermoluminescence light is proportional to the time that has passed from the last clock resetting event, which for ceramics correspond to when it was baked.
Electron trapping Energy absorbed from ionizing radiation frees electrons to move through the crystal lattice, where some are trapped at imperfections.
Later heating releases the trapped electrons, producing light whose intensity is proportional to the amount of radiation absorbed.
A sample of the earth also needs to be collected so environmental radiation can be tested.
The wetness of the soil and the sample should also be recorded.
