Module 7: Quality Assurance and Quality Control in Radiochemical Analysis


"Quality Assurance in Radiochemical Analyses: Overview of Requirements for the Laboratory" provides an overview of EPA' requirements for a laboratory’s organization, structure, training, and reporting and for measuring and maintaining control during laboratory analysis through proper use of QC samples and counting instruments. Several references to standards that provide detailed guidance on how to establish a QA and QC program are provided. These references and the EPA "Manual for the Certification of Laboratories Analyzing Drinking Water—Criteria and Procedures Quality Assurance" should be consulted for detailed requirements of the QA and QC program.
