How frequently must a physical inventory be conducted for regulated sources of radiation?

Conducting a physical inventory of regulated sources of radiation on a quarterly basis aligns with safety and regulatory requirements. This frequency ensures that organizations can adequately manage their radioactive materials, minimizing the risk of loss or misplacement, and maintaining compliance with regulatory standards set by agencies such as the Texas Department of State Health Services or the U.S. Nuclear Regulatory Commission.

A quarterly inventory allows sufficient time to track usage and changes in possession while still being frequent enough to identify any discrepancies in a timely manner. Conducting the inventory too infrequently might lead to difficulty in managing the sources effectively, while doing so too often could impose unnecessary administrative burdens without significantly enhancing safety. Thus, quarterly inventory strikes a balance between regulatory compliance and operational efficiency.
