Studying the effect of the geometric shapes of the screen and the projection devices (Computers) in Amount of radiation change
Abstract
Abstract The importance of this study is encountered in the fact that there is no lower limit for The dangerosity of radiation . The problem arises especially after the arrival of a number of visible devices with lower international standards Thermo luminescence Dosimeter.(TLD) and x-ray film were used to study the effect of geometrical shapes of the screens of these devices working with (20-40kV)on the amount of change in radiation dose emitted from these screens.
