The electrons that have been excited to the conduction band may become entrapped in the electron or hole traps.Under stimulation of light the electrons may free themselves from the trap and get into the conduction band.

OSL is used in at least two applications: optical dating of ancient materials: mainly geological sediments and sometimes fired pottery, bricks etc., although in the latter case thermoluminescence dating is used more often radiation dosimetry, which is the measurement of accumulated radiation dose in the tissues of health care, nuclear, research and other workers, as well as in building materials in regions of nuclear disaster To carry out OSL dating, mineral grains have to be extracted from the sample.Apart from medical surveillance, Occupational Health Doctors are also responsible for carrying out health surveillance for employees who work in confined spaces to ensure the health of workers involved is in the optimum condition both physically and mentally.Health surveillance for employees working in confined spaces are as outlined in the Industry Code of Practice For Safe Working In A Confined Space 2010.From the conduction band they may recombine with holes trapped in hole traps.
