Measurement of Entrance Skin Dose and Effective Dose in The most Common Diagnostic radiology Examinations in Jiroft, Iran
Introduction: Medical uses of radiation have grown very rapidly over in the past two decades, medical uses represent the largest source of exposure to people, The most important methods in medical diagnosis are the useses of diagnostic radiology exams. Although the use of these methods is very beneficial for the treatment of patients, but ionizing radiation produces ion pairs, ...
متن کاملEffective dose and thyroid cancer risk in panoramic imaging
Background and Aim: On panoramic radiographs, sensitive organs, including the thyroid, are exposed to radiation. Thyroid cancer is one of the most common cancers in Iran. That is why, in this study the effective dose and risk of thyroid cancer were estimated on panoramic radiography. Materials and Methods: Seventy GR200 thermoluminescence (TLD) dosimeters were used to estimate the absorbed dos...
متن کاملEffective dose and energy imparted in diagnostic radiology.
The patient effective dose, E, is an indicator of the stochastic radiation risk associated with radiographic or fluoroscopic x-ray examinations. Determining effective doses for radiologic examinations by measurement or calculation is generally very difficult. By contrast, the energy imparted, epsilon, to the patient may be obtained from the x-ray exposure-area product incident on the patient. A...
متن کاملEffective dose: a useful concept in diagnostic radiology.
Effective dose (E) was introduced by the International Commission of Radiological Protection (ICRP) to provide a summation of radiation doses to tissues and organs for radiological protection. For a non-uniform irradiation, E is designed to provide an estimate of the corresponding uniform whole-body dose that would result in the same stochastic detriment. E, which has the same units as equivale...
متن کاملApplication of Dose-Area Product compared with three other dosimetric quantities used to estimate patient effective dose in diagnostic radiology
Background: Application of Dose-area product (DAP) quantity has been increased in the clinical practice. DAP is relatively easy to measure. DAP has been shown to correlate well with the total energy imparted to the patient, which is related to the effective dose. Material and Methods: In this study, measurements of DAP were carried out in a sample of 421 adult patients who underwent convention...
