In the past few decades, man has created hundreds of radionuclides artificially for a range of uses, including smoke alarms, illuminating displays, radiation, and medical diagnosis.  These uses result in higher radiation exposure levels to Man.  Man-made applications have a direct impact on the demographic groups that use them, in contrast to natural background radiation exposures, which influence the entire population.  The majority of man-made sources are under control, and the amount that people are exposed to is directly correlated with the nation's level of industrial and economic development.In CT imaging, survey or localizer radiographs are essential.  However, radiologists and radiographers frequently lack knowledge of the localizer radiograph's many roles and functions. The issue of radiation exposure has received significant attention in the public consciousness community, despite its advantages for diagnostics.  According to recent studies, CT procedures make up roughly 10% of all diagnostic imaging tests and 62% of the total effective radiation exposure dosage related to healthcare.
