scope:

This standard sets forth guidelines and performance-based criteria for the design and use of systems for sampling the releases of airborne radioactive substances from the ducts and stacks of nuclear facilities.

Relationship to other standards The potential applications of this standard are diverse, and consequently it is inappropriate to incorporate the many laws, regulations, and guidelines of governmental bodies that have an interest in the measurement of radioactive air emissions. It is incumbent on the user to be familiar with the applicable regulations.

Application of this standard The requirements presented in this standard are aimed at sampling programs conducted for regulatory compliance. These requirements may not be universally applicable to all sampling programs, especially those with more limited objectives such as process control. When designing systems with objectives other than regulatory compliance, the designer should exercise professional judgement in the application of these requirements and should explicitly document the sampling objectives and the reasons for any exceptions to the requirements of this standard.
