Radiation cancer risk from doses to newborn infants hospitalized in neonatal intensive care units in children hospitals of Isfahan province

Background: this study aimed to invesgate dose area product (dap), effectivedose, and radiation risk in newborn infants hospitalized in neonatal intensive careunits in isfahan and kashan. materials and methods: during a period of sixmonths, dap for chest x-ray examinations for newborn infants hospitalized innicus of five special hospitals including behesh (in kashan), al-zahra, imamhossein, amin and goldis (in isfahan) were measured using dap meter. then, usingthe dose area product (dap) and conversion coefficients, the effective dose wascalculated. radiation risk per single exposure was esmated by applying 2.8 × 10-2and 13 × 10-2 factors per sievert. also, to estimate the radiation risk in the exposedpopulaon, the collecve effecve dose and the menoned factors were used.results: the mean dap, the effecve dose, the radiaon risk per singleexposure, and the radiation risk in the exposed population were found to be15.37 ± (1.19), 45.52 ± (3.28), [1.27-5.91] × 10-6, and [0.0045-0.021],respectively. conclusion: findings indicate that the effective dose and thereforeradiation risk in nicus for newborn infants is higher than that of other studied citiesin iran. consequently, it is necessary to acempt to reduce radiation dose whilemaintaining the image quality. in addition, theoreyical and practical trainingprograms are needed to increase the knowledge and skills of radiologictechnologists on the concept of as low as reasonably achievable (alara) andpossible radiation cancer risks.
