Our study aims to determine diagnostic reference levels (DRL) for chest front\nexamination in postero anterior (PA) for optimizing patient entrance surface\ndose (ESD) and dose-area product (DAP) of patients in west of Cote dâ??Ivoire.\n90 patients from three hospitals undergoing conventional radiology were\nconsidered. The ESD and DAP for each patient were obtained during chest\nradiography (PA) examination. The measurements were performed with the\ndevice call Dose-Area Product-meter (DAP-meter) with brand Diamentor\nM4-KDK, type 11017. The DRL were obtained in applying the 75th percentile\nstatistical method to the obtained ESD and DAP. The obtained DRL in ESD\nfor chest radiography for all rooms is 0.40 mGy and in DAP is 54.85 cGy.cm^2.\nOur DRL for ESD is higher than those obtained in Abidjan District and in\nother countries like UK and Cameroon. Our DRL for DAP is higher than\nthose from Abidjan and all other countries for which a similar study was\nmade. The comparison of these values to those from Abidjan and other\ncountries, shows us that radiology technicians can make efforts to choose radiological\nparameters to reduce ESD. They must use convenable the X-rays\ntube to reduce DAP by reducing the patient exposure surface.
