Abstrakt:	Quantifying the radiological risk from diagnostic radiography is essential for patients' safety. Effective dose is considered the best quantity to determine the stochastic risk associated with the radiological examinations. Therefore, the present work investigated organ and effective dose for adult patients in the most common type of X-ray examinations, such as the chest (PA/LAT), abdomen (AP) and lumbar spine (AP/LAT) projections. The PCXMC version 2 Monte Carlo program was used to estimate the organ and effective dose for 547 patients who underwent a radiographic examination at the King Abdulaziz Hospital, Saudi Arabia. The results showed wide variation in organ doses. The largest organ dose in each X-ray examination were 2.72 mGy for the spleen in the lumbar spine (LAT), 1.98 mGy for the urinary bladder in the lumbar spine (AP), 0.40 mGy for the spleen in the chest (PA), 0.11 mGy for the kidney in the chest (LAT) and 1.78 mGy for the testicles in the abdomen (AP) examinations. Values for the effective dose were estimated for each investigated X-ray examination, and the results were compared with the published values available in the literature. The obtained values for effective dose were relatively lower than those reported by the European Commission and the United Nations Scientific Committee on the Effects of Atomic Radiation for the same examinations. The results presented here will help establish a database that will be useful for future comparisons and monitoring in radiographic procedures. (© The Author(s) 2021.
