In recent years a new potential for application of lasers has been realized. In thermoluminescence (TL) radiation dosimetry, traditionally, the phosphor is heated resistively on a planchet at a rate of 1–20 Ksec−1. The use of IR lasers, such as a CO2 laser, can result in heating rates as high as 104 Ksec−1 due to direct coupling of incident photons with the optical phonons of the phosphor lattice.1 These enhanced heating rates dramatically improve the SNR in thermoluminescence dosimetry enabling the determination of very small doses of nuclear radiation for personnel dosimetry. Alternately microdosimetry is possible utilizing a few micrograms of material for estimating radiation dose.
