waste:
Material for which no further use is foreseen.

waste, radioactive:
1.   For legal and regulatory purposes, waste that contains or is contaminated with, radionuclides at concentrations or activities greater than clearance levels as established by the regulatory body.
It should be recognized that this definition is purely for regulatory purposes, and that material with activity concentrations equal to or less than clearance levels is radioactive from a physical viewpoint, although the associated radiological hazards are considered negligible.
2.   [Radioactive material in gaseous, liquid or solid form for which no further use is foreseen by the Contracting Party or by a natural or legal person whose decision is accepted by the Contracting Party, and which is controlled as radioactive waste by a regulatory body under the legislative and regulatory framework of the Contracting Party.] [7]
3.   Material, whatever its physical form, remaining from practices or interventions and for which no further use is foreseen (i) that contains or is contaminated with radioactive substances and has an activity or activity concentration higher than the level for clearance from regulatory requirements, and (ii) exposure to which is not excluded from the Standards. [40]

waste acceptance requirements:
Quantitative or qualitative criteria specified by the regulatory body, or specified by an operator and approved by the regulatory body, for radioactive waste to be accepted by the operator of a repository for disposal, or by the operator of a storage facility for storage.
Waste acceptance requirements might include, for example, restrictions on the activity concentration or total activity of particular radionuclides (or types of radionuclide) in the waste or requirements concerning the waste form or packaging of the waste.

waste classes:

Classes not in square brackets are those recommended in Safety Series 111-G-1.1 [62]. This classification system is organized to take into account matters considered of prime importance for disposal safety. A number of issues related to waste classification are currently under review.
The other classes listed below (in square brackets) are sometimes used, e.g. in national classification systems, and are mentioned here to indicate how they typically relate to the classes from Ref. [62].
Other systems classify waste on other bases, such as according to its origin (e.g. reactor operations waste, reprocessing waste, decommissioning waste, defence waste, etc.).

waste disposal:
See disposal.

waste form:
Waste in its physical and chemical form after treatment and/or conditioning (resulting in a solid product) prior to packaging.  The waste form is a component of the waste package.

waste generator:
The operating organization of a facility or activity that generates waste.

! For convenience, the scope of the term waste generator is sometimes extended to include whoever currently has the responsibilities of the waste generator (e.g. if the actual waste generator is unknown or no longer exists, and a successor organization has assumed responsibility for the waste).

waste management:
1.   All administrative and operational activities involved in the handling, pretreatment, treatment, conditioning, transport, storage and disposal of radioactive waste.

2.   All activities, including decommissioning activities, that relate to the handling, pretreatment, treatment, conditioning, storage, or disposal of radioactive waste, excluding off-site transportation.  It may also involve discharges. [13]

waste package:
See package, waste.

worker:
Any person who works, whether full time, part time or temporarily, for an employer and who has recognized rights and duties in relation to occupational radiation protection.  (A self-employed person is regarded as having the duties of both an employer and a worker.). [40]
