What documentation is crucial for radiographic operations according to Texas regulations?

The correct choice highlights the importance of having a license for the radioactive source and established operating procedures, which are vital components in ensuring compliance with Texas regulations governing radiographic operations. A license ensures that all radioactive sources used for industrial radiography are properly authorized and adhere to safety and regulatory standards set forth by both state and federal guidelines. This is crucial for protecting the health and safety of workers and the public, as well as minimizing environmental impacts.

Furthermore, documented operating procedures are essential as they provide standardized guidelines for conducting radiographic operations safely and effectively. These procedures help ensure that personnel apply industry best practices and comply with regulatory requirements, which is key in a field where exposure to radiation is a significant concern. The combination of licensing and procedural documentation forms the backbone of responsible radiographic practices, ensuring that all activities are performed legally, safely, and effectively.
