AQUINO IGNACIO, Marino Crispín et al. Quantification of the absorbed doses by means of dosimetry thermoluminiscent in dental radiology. Rev. Odont. Mex [online]. 2010, vol.14, n.4, pp.231-236. ISSN 1870-199X.

After the discovery of Roentgen rays, in 1895, different studies were made, discovering the injurious effects that handling this type of ionizing radiation entails, depending on the amount of radiation(1), the absorbed dose and the sensitivity of the tissues to the radiation. These side-effects could be dermatitis, anemias, and hemophilias and in other cases some scientists were mutilated of parts of their body due to necrosis. (2) The effects that caused the ionizing radiations with protective material and equipment for the operator and the patient, such as termoluminiscense dosimeters and termoluminiscense reading equipment were studied. It was observed that annual limits of dose constitute a fundamental guideline in protection of the ionizing radiations. Current limits of dose are mentioned in the NOM-229-SSA 1-2002, as well as in the General Regulation of Radiologic Security. The objectives of the present study were to quantify the absorbed dose for patients and for the occupational exposed personnel (POE) and physical area, according to NOM-229-SSA 1-2002, and also to evaluate if the intraoral and extraoral X-rays in dentistry are an important risk within the exposure to ionizing radiations.
