				meaning specified in ARM
				17.50.502.
(10) "Health physicist" means a scientist or
				engineer that has sufficient training and experience to make sound professional
				judgments regarding radiation monitoring, equipment, environmental protection,
				health, and safety. The training and experience must pertain to naturally
				occurring radioactive materials and health physics concerning protecting people
				and the environment from potential radiation hazards. Sufficient training and
				experience is gained through a baccalaureate and/or post-graduate degree in the
				natural sciences or engineering, professional certifications, and work
				experience.
(11) "Landfill" has the
				meaning specified in ARM 17.50.502.
(12) "Leachate" has the meaning specified in
				ARM 17.50.502.
(13) "Leachate
				collection system" has the meaning specified in ARM 17.50.502.
(14) "Leachate removal system" has the
				meaning specified in ARM 17.50.502.
(15) "Licensed boundary" has the meaning
				specified in ARM 17.50.502.
(16)
				"Load" is a measured quantity of waste prepared for or being transported at any
				one time.
(17) "Method of receipt"
				means the name of the transporter and equipment used to deliver the waste to
				the TENORM waste management system.
(18) "Microroentgen" (µR) is one
				millionth of a roentgen.
(19)
				"Millirem" (mrem) means a unit of equivalent dose that is equal to one
				thousandth of a rem.
(20)
				"Milliroentgen" (mR) means a unit of measurement for radiation exposure that is
				one thousandth of a roentgen.
(21)
				"Picocuries" is a unit of radioactivity that is one trillionth of a
				curie.
(22) "Qualifiedground water
				scientist" has the meaning specified in ARM
				17.50.1302.
(23) "Radiation" means alpha particles, beta
				particles, gamma rays, x-rays, neutrons, high-speed electrons, high-speed
				protons, and other particles with sufficient kinetic energy to strip electrons
				from atoms. Radiation does not include non-ionizing radiation, such as radio or
				microwaves, or visible, infrared, or ultraviolet light.
(24) "Rem" or "roentgen equivalent man" is
				the dose unit representing the amount of energy absorbed in human tissue, the
				distribution of the energy, and the sensitivity of the whole body or individual
				organs to radiation.
(25)
				"Roentgen" (R) is the unit of measurement for x-radiation or gamma radiation
				producing one electrostatic unit of positive or negative ionic charge in one
				cubic centimeter of air under standard pressure or 0.000258 coulombs per
				kilogram of dry air.
(26)
				"Screening" means the examination and measurement procedures to verify that
				incoming waste meets the acceptance criteria for the waste management
				system.
(27) "Solid waste" has the
				meaning specified in ARM 17.50.403.
(28) "Solid waste management system" has the
				meaning specified in ARM 17.50.403.
(29) "Source" means the location where the
				TENORM waste is generated or, if aggregated, the location where the last
				aggregation occurs.
(30) "Spill"
				means the accidental or unintentional release of TENORM waste during transport
				or onsite at the TENORM waste management system in an area not designated for
				disposal.
(31) "Storage" has the
				meaning specified in ARM 17.50.403.
(32) "Technologically enhanced naturally
				occurring radioactive material" (TENORM) means naturally occurring radioactive
				material whose radionuclide concentrations are increased by or as a result of
				past or present human practices. TENORM does not include background radiation
				or the natural radioactivity of rocks and soils. TENORM does not include
				"source material" and "byproduct material," as both are defined in
				42
				USC §
										2014, a section of the Atomic
				Energy Act of 1954.
(33) "TENORM
				surface-contaminated objects" means objects that have TENORM distributed on
				either the external or internal surfaces, or both, including but not limited to
				pipes, valve stems, and equipment or survey instruments.
(34) "TENORM waste" is solid waste that
				contains TENORM.
(35) "TENORM waste
				management system" means a system that accepts, stores, treats, recycles,
				recovers, disposes, or transports TENORM waste. Such a system may be composed
				of one or more waste management facilities. This term does not include
				hazardous waste management systems.
(36) "TENORM waste unit" means a discrete
				area of land or an excavation used for the landfilling or other disposal of
				TENORM waste at a TENORM waste management system.
(37) "Total Effective Dose Equivalent" (TEDE)
				means the overall measured and/or calculated effective dose that takes into
				account the type of radiation and the nature of each organ or tissue being
				irradiated.

				meaning specified in ARM 17.50.502.
(41) "Waste characterization" means the
				standardized process for analyzing the composition of different waste
				streams.
