A review of 20 years publication in the field of radiation protection in diagnostic radiology in Iran

Abstract

In recent years, knowing the risks of stochastic effects of radiation, patient dose in diagnostic radiology is taken in to consideration extensively. Many countries and international organization, including International Commission on Radiological Protection, use quantities such as dose area product, entrance surface dose, etc. in radiological investigations, which serve as a guide for patient dose reduction. The concept of diagnostic reference level (DRL) is used to optimizing the dose of patients undergoing diagnostic radiology examinations. The present study aimed to review the studies on the DRLs in Iran. This study was conducted to review the status of patient dose in diagnostic radiology in Iran. A comprehensive literature search was performed without time constraints in the popular databases such as Google Scholar, Medline, Embase, PubMed, Irandoc, Iran Medex, Magiran and Scientific Information Database under the key words ‘Entrance Surface Dose’, ‘dose area product, ‘diagnostic reference level’ and ‘DRL’ in Iran. Data on the radiation dose to patients has demonstrated further reductions in patient doses in the Iran. Considering advanced techniques and dose reduction methodologies complicates comparability between studies. Joint efforts of experts in the field of radiological protection and medical imaging and training program are necessary for achieving an acceptable condition.
