Characterization
Characterization : (1) Determination of the nature and activity of radionuclides present in a specified place. For example, determination of the radionuclides present in a bioassay sample or in an area contaminated with radioactive material (e.g. as a first step in planning remediation). For the latter example, care should be taken to avoid confusion with the existing, and different, definition of the term site characterization. (2) Determination of the character of something. This is the standard dictionary definition, and would not need to be included in an individual glossary. It is included here only to distinguish the normal usage from the more restricted usage indicated in (1). site characterization: Detailed surface and subsurface investigations and activities at a site to determine the radiological conditions at the site or to evaluate candidate disposal sites to obtain information to determine the suitability of the site for a repository and to evaluate the long term performance of a repository at the site. Site characterization is a stage in the siting of a repository; it follows area survey and precedes site confirmation. Site characterization may also refer to the siting process for any other authorized facility. See also: Site evaluation, which includes site characterization and is not specific to a repository site, and area survey. Waste Characterization : Determination of the physical, chemical and radiological properties of the waste to establish the need for further adjustment, treatment or conditioning, or its suitability for further handling, processing, storage or disposal
