520 _aThis work aims at designing a computer program to calculate the necessary amount of shielding for a given or proposed linear accelerator room design in radiotherapy. The program (Shield Calculation in Radiotherapy, SCR) is developed using Microsoft Visual Basic. It applies the treatment room shielding calculations of the NCRP report no. 151 to calculate proper shielding thicknesses for a given linear accelerator treatment room design. The program is composed of six main user-friendly interfaces. The first one enables the user to upload whatever treatment room design of his choice and to measure the distances required for shielding calculations. The second interface enables the user to calculate the primary barrier thickness in case of 3-Dimensional Conventional Radiotherapy (3D-CRT), Intensity Modulated Radiotherapy (IMRT) and Total Body Irradiation (TBI). The third interface calculates the secondary barrier thickness due to both scattered and leakage radiation. The fourth and fifth interfaces provide a means to calculate the photon dose equivalent for low and high energy radiation, respectively, in door and maze areas. The six interface enables the user to calculate the skyshine radiation for photons and neutrons
