Radiation dose imparted to patients during diagnostic radiology is of concern, since this has the potential to cause stochastic and deterministic effects. Radiation risk and work practices were evaluated for 42 patients who underwent hysteroisalpingography (HSG) examinations using digital imaging system. Dose Area Product (DAP) meter was used for measuring DAP and values obtained were used in estimating entrance surface dose (ESD), effective dose and organ dose. Patients who underwent HSG examinations were categorized into three groups depending upon their thickness. During HSG examinations, ESD varied from 0.19 mGy to 17.07 mGy, effective dose varied from 0.01 mSv to 0.95 mSv and ovarian doses varied from 0.15 mGy to 0.43 mGy, depending upon the individual thicknesses of patients. Precise collimation, selection of appropriate field sizes and use of 0.2 mm copper filler, had an effect on reduction of radiation dose imparted to patients during HSG examinations.
