Background: X-ray examination is associated with the patient’s exposure to ionizing radiation. The dose values depend on the type of the medical procedure used, the X-ray unit technical condition and exposure conditions selected by X-ray technicians. The aim of this study has been to assess the entrance surface dose (ESD) values received by patients during the limb X-ray examination. The results should help doctors in making the decision about sending patients for X-ray examination. At the same time the X-ray unit condition and examination method performance are important for the radiological protection of the medical staff. Material and Methods: The study covered the total number of 118 X-ray units located in 56 public healthcare entities and private medical centers in the Masovian Voivodeship. The measurement of the radiation dose rate received by patients was based on our own research procedures. Results: The research has found that there are even more than 10-fold differences in the dose values received by adult patients with several-fold differences in the case of children patients. The broadest dose value range for adult patients was related to femur radiography. The ESD values for this procedure ranged 70.9–765.2 μGy (with the average value of 319.7 μGy). The broadest dose value range for children was related to the knee radiography. The range for children aged 5 years old was 11.8–95.8 μGy (with the average value of 48.9 μGy). Conclusions: It is essential to immediately implement X-ray room working procedures for the purpose of performing diagnostic examinations based on the existing model procedures.
