Background and purpose: Most exposure of people to artificial sources through diagnostic radiographs is due to the increase of these tests in the community and the inevitability of these tests. Optimizing the dose of skin inlet can play an important role in reducing radiation exposure, which can be achieved by monitoring the inlet dose as a key parameter.

The purpose of this study was to evaluate the rate of skin input dose in routine radiographic tests at Loghman Hakim Hospital in Tehran to compare the doses recommended by the International Commission for Protection against Radiation (ICRP) as well as, if possible, to provide simple guidelines for dose reduction and optimization. Patients with preserved image quality.
Materials and Methods: This descriptive study was performed in Loghman Hakim public hospital in Tehran with 235 patients 100 females and 135 males with a weight range of ± 10 kg. In this study, skin doses of patients were measured using four diagnostic radiographs of IAEA standards, in 12 common radiographic views using thermoluminescence chips and Geiger Müller dosimeter.
Results: The doses of skin for each radiographic method in milligrays were as follows: Chest (posterior-anterior) 0.34, Chest (1.85), Abdominal (anterior-posterior) 3.31 , Hip (anterior-posterior) 4.79, cervical (anterior-posterior) 1.95, cervical vertebra (1.24), dorsal (anterior-posterior) 2.38, dorsal vertebrae (profile) 4.68), lumbar vertebrae 3.95, lumbar vertebrae 9.53, skull (antero-posterior) 29.2 and skull 1.89.
Conclusion: This study shows that the rate of skin inlet dose in the twelve investigated facets was in accordance with the recommended doses and was in line with the standards provided by the International Commission for Protection against ICRP and also optimized the radiation parameters. And standardizing radiographic conditions by preserving the image quality will reduce the dose received by patients. In this regard, dosimetry at regular intervals and periodic and regular quality control tests of radiographic devices can be optimized, monitored, reduced dose. And protecting patients as well as assessing potential harm The object of radiation will be effective.
