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

The correct term for the ball on a source assembly that prevents the source from exiting through the back of the camera is known as the safety stop ball. This component is designed as a critical safety feature. Its primary purpose is to ensure that in the event of a malfunction or improper handling, the radioactive source cannot inadvertently leave the confines of the camera assembly.

The inclusion of such a feature is essential for maintaining safety protocols in radiation protection, as it helps to mitigate the risk of accidental exposure to radiation by ensuring that the source remains secured within the assembly.

Understanding the function of the safety stop ball is vital for anyone working with radiographic equipment, as it underscores the importance of engineering controls in radiation safety practices. Familiarity with these components not only helps in recognizing their operational significance but also emphasizes the safety measures in place to protect users and the surrounding environment.
