Content:
ormance: An affirmative indication or judgment that a product or service has met the criteria of the relevant specifications, contract, or regulation; also the state of meeting the criteria (ANSI/ASQC E4-1994). corrective actions: Those measures taken to prevent, rectify, or eliminate conditions adverse to quality or detected nonconformities and — as necessary — to preclude repetition of those conditions. Appendix A to DG-4010, Page A-3 data quality objective (DQO): Qualitative and quantitative statements that clarify the study objectives, define the most appropriate type of data to collect, determine the most appropriate conditions from which to collect the data, and specify tolerable limits on decision error rates. Because DQOs will be used to establish the quality and quantity of data needed to support decisions, they should encompass the total UNCERTAINTY resulting from all data collection activities, including analytical and sampling activities. directed planning process: A systematic framework focused on defining the data needed to support an informed decision for a specific project. Directed planning provides a logic for setting well- defined, achievable objectives and developing a cost-effective, technically sound sampling and analysis design that balances the data user’s tolerance for UNCERTAINTY in the decision process and the available resources for obtaining data to support a decision. Directed planning helps to eliminate unnecessary, poor, or inadequate sampling and analysis designs. dose equivalent: Quantity that expresses all radiations on a common scale for calculating the effective absorbed dose. This quantity is the product of absorbed dose (GRAYS (Gy) or rads) multiplied by a quality factor and any other modifying factors (MARSSIM). The quality factor adjusts the absorbed dose because not all types of ionizing radiation create the same effect on human tissue. For example, a dose equivalent of one SIEVERT (Sv) requires 1 Gy of beta or gamma
