y and other societal and socioeconomic considerations, and in relation to the use of atomic energy in the public interest” (10 USC 50.34a). assessment: A planned and documented activity performed to determine whether various elements within a quality management system are effective in achieving stated quality objectives (ANSI N42.23-2003). audit: A planned and documented activity performed to determine by investigation, examination, or evaluation of objective evidence the adequacy of, and CONFORMANCE with, established procedures, instructions, drawings, and other applicable documents as well as the effectiveness of implementation. An audit should not be confused with surveillance or inspection activities performed for the sole purpose of process control or product acceptance (after ANSI N42.23- 2003). background (instrument): Radiation detected by an instrument when no SOURCE is present. The background radiation that is detected may come from radionuclides in the materials of construction of the detector, its housing, its electronics, and the building as well as the environment and natural radiation. Appendix A to DG-4010, Page A-2 background level: A term that usually refers to the presence of radioactivity or radiation in the environment. From an analytical perspective, the presence of background radioactivity in samples needs to be considered when clarifying the radioanalytical aspects of the decision or study question. Many radionuclides are present in measurable quantities in the environment. bias (of a measurement process): A persistent deviation of the mean measured result from the true or accepted reference value of the quantity being measured, which does not vary if a measurement is repeated. blank (analytical or method): A SAMPLE that is assumed to be essentially free of the TARGET ANALYTE (the “unknown”), that is carried through the radiochemical preparation, analysis, mounting, and measurement process in the same manner as a routine sample of a
