Radiation Exposure of the Patient during X-Ray Examination with the ProScan Chest X-Ray Survey Unit

XRay radiation dose characteristics were measured in the chamber of the ProScan�2000 chest Xray survey unit, in transparent plastic, and in a Torrance model Pelican Products (USA) human body phantom made of tissueequivalent rubber. Measuring conditions were sim� ulated using the Monte Carlo GEANT program. Results of measurements were compared with model data. A method for assessment of the dose of patient radiation exposure using chest Xray survey unit detector is sug� gested. The error of the measurement is estimated.
