TL dosimeters

TLD Most of the interest in TL comes from the possibility of using it in radiation dosimetry. Radiation is an important tool in nuclear and medical research programs. Since radiation is hazardous, it is necessary to monitor the dose to woikers who are involved in snch programs. There are many devices to measure the radiation dose. The TL dosimeter is one of them. It is inexpensive and very sensitive to radiation. Use is made of the fact that ionizing... 

The studies of TL response of AIN to ionizing radiation were performed in comparison with other well-known and widely used TL dosimeters such as AI2O3 C, LiF Mg,Ti, and LiF Mg,Cu,P [27]. It was found that AlN ceramics reveals a number of very attractive properties, such as ...

The quality of phosphors and their suitabihty for practical devices, e.g. radiation dosimeters, depend on the dopants used, on their concentration and on other fiictors as will be shown below. The lanthanides, R, play a unique role in the production of high-sensitivity reliable TL dosimeters. The present article will give a review of the advance in the investigation of fire properties of R-containing phosphors and in fire TL dosimeters based on these phosphors. 

Automatic computerized glow curve analyzers were developed for large-scale monitoring of the output of TL dosimeters as described by Vana et al. (1988), by Sabre and Schonmuth (1993) and by others.
