What is the primary purpose of a "master inventory" in radiation safety?

The primary purpose of a "master inventory" in radiation safety is to track the quantity and location of all radioactive materials. This inventory is essential for ensuring compliance with regulations and maintaining safety protocols within an organization that handles radioactive substances. By keeping an accurate record of radioactive materials, safety officers can monitor usage, assess potential risks, and conduct audits to confirm that materials are stored and disposed of correctly. This accountability helps prevent unauthorized access, loss, or accidental exposure to radioactive materials, significantly enhancing the overall safety of the environment where these materials are used. The master inventory also facilitates emergency response planning and inventory management, which are critical for maintaining a safe working environment.
