Radiation Doses in Diagnostic Radiology and Method for Dose Reduction

Objective: The current research study aims to calculate entrance surface air kerma for skull, chest, cervical spine, lumbar and pelvic X-ray examinations in interior posterior positions generate a method chest dose reduction decrease radiation risk. Materials Methods: indirect measurement was used the research. tube output measured using RAD-CHECK Plus ionization chamber calculated via applying physical acquisition parameters such as focus on skin distance, times exposure time (mAs), applied voltage (kV), mathematical model. Results: main findings were obtained from comparing doses with reference levels of International organizations American College Radiology Atomic Energy Authority. mean skull (AP), (PA), (LAT), spine pelvis (LAT) adult within diagnostic level values by ACR (2018) except ESD (AP) which 0.88 mGy. Conclusions: results concluded that adjusting voltage, kV, product time, mAs decreased 58%.
