Abstract

There are analytic methods for designing protective barriers however, they lack sufficient efficiency and considering the NCRP (National Council on Radiation Protection and measurements) reports, designing mechanical protective barrier in order to protect the initial x-ray radiation and absorption of the ray quality of such radiation is different. In this study, computer software was designed to calculate the needed barrier with high accuracy. For proper determination of thickness of the protective barrier, relevant information about curves of radiation weakness, dose limit and other items should be entered. This program was done in windows and designed in such a way that the operator works easily, flexibility of the program is acceptable and its accuracy and sensitivity is high. Meanwhile sometimes shielding is more than what required which lacks technical standards and cost effectiveness. When the application index is contrasting zero, thickness of NCRP49 calculation is about 20% less than the calculated rate done by the method of this study. The multi radiation sources in a single room are considered and non guaranteed radiation of NCRP hypothesis is removed. Difference between the theoretical and calculated rates of this method is X2 =10-5 which indicates accuracy and high efficiency of this software.
