Content:
iation doses are often measured in mSv. An effective dose of 1 Sv requires 1 GRAY of beta or gamma radiation, but only 0.05 Gy of alpha radiation or 0.1 Gy of neutron radiation. source, radioactive: A quantity of material configured for radiation measurement. spike: A known amount of TARGET ANALYTE added to the environmental sample to establish whether the method or procedure is appropriate for the analysis of the particular matrix and how the TARGET ANALYTE responds when the environmental sample is prepared and measured, thereby estimating the bias introduced by the sample matrix. Also termed MATRIX SPIKE. standard reference material: A CERTIFIED REFERENCE MATERIAL issued by NIST in the United States. NIST certifies a standard reference material for specific chemical or physical properties and issues it with a certificate that reports the results of the characterization and indicates the intended use of the material. Appendix A to DG-4010, Page A-7 surveillance: Continual or frequent monitoring and verification of the status of an activity and the analysis of records to ensure that specified requirements are being fulfilled. A surveillance is less extensive and more frequent than an AUDIT and concentrates on a single item or activity. survey: A systematic evaluation and documentation of radiological measurements with a correctly calibrated instrument or instruments that meet the sensitivity required by the objective of the evaluation. target analyte: A radionuclide on the list of radionuclides of interest or a radionuclide of concern for a project. test source: The final radioanalytical processing product or matrix (e.g., precipitate, solution, filter) that is introduced into a measurement instrument. A test source is prepared from laboratory sample material for the purpose of determining its radioactive constituents. See CALIBRATION SOURCE, CHECK SOURCE, and SOURCE, RADIOACTIVE. total effective dose equivalent: The sum of the effective dose equivalent (for
