What is the name of the ball on a source assembly that prevents the source from exiting through the back of the camera?

Source ball
Stop ball
Safety ball
Shield ball

The correct answer is: Stop ball

The term used to describe the ball in a source assembly that prevents the source from exiting through the back of the camera is commonly referred to as the "stop ball." This component plays a crucial role in maintaining safety during the operation of the radiographic equipment. Its primary function is to act as a physical barrier that ensures the radioactive source remains securely contained within the camera assembly when it is not in use. By preventing the source from accidentally being ejected, the stop ball significantly reduces the risk of radiation exposure to operators and others nearby. It is an essential safety feature designed to comply with regulatory standards and promote safe practices in industrial radiography.
