The amount of light produced is proportional to the number of trapped electrons that have been freed which is in turn proportional to the radiation dose accumulated. In other words, the OSL date on a foundation wall of a building is the last time that foundation was exposed to light before being used as the initial layers in a building, and hence when the building was first built. Saunders, who thought the thermoluminescence response of pottery shards could date the last incidence of heating. In addition, it can be used to date materials that cannot be dated with these other two methods. Eras Epochs.

However, it poses a serious problem for. The radiation dose rate is calculated from measurements of the radioactive elements K, U, Th and Rb within the sample and its surroundings and the radiation dose rate from cosmic rays. Search this site.
