Can carbon dating false

This usually occurs when the items are heated to 350 degrees Celsius.Therefore, in archaeology, thermoluminescence dating works best for ceramics, cooking hearths, incidentally fire-cracked rocks, and deliberately fire-treated rocks, such as flint or chert.When the sample is heated in the lab, it releases thermoluminescence light.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.Instead, a less sophisticated method that would deceive TL testing is to reuse original broken and unmarketable pieces.Forgers commonly use the bottom of an original broken vessel, which has no commercial value, and make a new fake vessel on top of it.Create fake pottery that will pass the thermoluminescence test One way to pass a fake through a TL test is to expose the newly-made pottery to a high dose of artificial radiation sources, thus fooling the measurement instruments.

Therefore, thermoluminescence dating is actually determining the last time a crystal was heated and electrons were released.Indeed, the figure shows an automatic instrumentation which allows measurement of thermoluminescence light from samples and also the determination of the dose rate per year.This last procedure involves the use of a radioactive source, though very weak.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.

Then we need to correlate thermoluminescence light to radiation dose rate per year which the sample has received since its last clock resetting event.
