ASTM C1718 is a technical standard for the nondestructive assay of radioactive material by tomographic gamma scanning. It provides a structured approach for evaluating radioactive contents without opening or altering the item being measured, which can be important for safety, accountability, and waste characterization. By defining a recognized test method, ASTM C1718 supports more consistent measurements and helps users compare results with greater confidence in regulated and quality-controlled environments.

Overview of ASTM C1718

The Standard Test Method for Nondestructive Assay of Radioactive Material by Tomographic Gamma Scanning describes a measurement approach based on gamma scanning and tomographic reconstruction concepts. As an ASTM standard, it is intended to support a repeatable technical method for assessing radioactive material while keeping the sample or container intact. This makes ASTM C1718 relevant where accurate assay results are needed, but intrusive sampling is not practical or desirable. It is generally used as a reference for method selection, procedure development, and compliance-oriented measurement programs.

Common use cases of ASTM C1718

This standard is commonly used in settings that require nondestructive evaluation of radioactive material, especially when the contents of a container, package, or similar item must be measured without opening it. It may be applied in waste management, inventory verification, characterization workflows, and other radiation-related measurement programs. ASTM C1718 is especially useful when tomographic gamma scanning is selected as the assay technique and a documented, standardized method is needed for consistent execution and reporting.

Benefits of using ASTM C1718

Using ASTM C1718 can help improve consistency in radioactive material assay by providing a recognized framework for nondestructive measurement. It supports quality control by helping users apply the same technical method across similar items and measurement campaigns. For procurement and compliance purposes, the standard also offers a clear point of reference when specifying assay requirements or reviewing technical documentation. In practice, that can reduce uncertainty, support defensible results, and improve confidence in operational decisions.
