Abstract
The diamond has extraordinary physical and chemical properties. This material by having a Zeff (atomic number-cash) equivalent to the human tissue is converted into a material suitable for use as a dosimeter of radiation. In this work, the properties of response to Afterglow (AG), Thermoluminescence (TL) and Optically Stimulated Luminescence (OSL) in HPHT diamond type lb (high temperature and high pressure diamond) are studied when subjected to lightning X (0.75 mA, 35 kV). The properties dosimetric curve and the TL were obtained on a computer Riso TL/OSL, where studies of fading (fading thermoluminescent), show that after a time of 1 hour, it stabilizes the signal TL and the reproducibility presents an error signal is not greater 5%. It is linearity in the three techniques for absorbed dose between 0-2 Gy. Between 2-9 Gy can be considered a response supralineal for the three techniques used and obtained a saturation of the sample to the absorbed doses increased to 9 Gy. It is showed that this material presents a promising future as a dosimeter in clinical radiation beams soft, used especially for radiation dosimetry for clinical use. © 2017. Acad. Colomb. Cienc. Ex.
