To which aspect of radiation safety does the safety stop ball primarily contribute?

The safety stop ball primarily contributes to source integrity in radiation safety. Source integrity involves ensuring that the radioactive source remains contained and does not lead to unintended exposure or contamination. The safety stop ball serves as a crucial mechanism that helps prevent accidental exposure by ensuring that the source is securely positioned and cannot be moved or accessed unintentionally.

Maintaining source integrity is critical because it reduces the risk of radiation leaks or accidents during operation, thereby protecting both personnel and the environment from exposure. This element of safety is foundational in managing the risks associated with radioactive materials and ensuring compliance with safety regulations.
