Oregon Administrative Rules › Chapter 333 - OREGON HEALTH AUTHORITY, PUBLIC HEALTH DIVISION › Division 113 - RADIATION SAFETY REQUIREMENTS FOR WIRELINE SERVICE OPERATIONS AND SUB-SURFACE TRACER STUDIES › Section 333-113-0005 - Definitions

Current through Register Vol. 63, No. 7, July 1, 2024
As used in this division, the following definitions
				apply:
(1) "Energy compensation source
			 (ECS)" means a small sealed source, with an activity not exceeding 3.7 MBq (100
			 microcuries), used within a well logging tool, or other tool components, to
			 provide a reference standard to maintain the tool's calibration when in
			 use.
(2) "Field Station" means a
			 facility where radioactive sources may be stored or used and from which
			 equipment is dispatched to temporary jobsites.
(3) "Fresh water aquifer," for the purpose of
			 this part, means a geologic formation that is capable of yielding fresh water
			 to a well or spring.
(4) "Injection
			 Tool" means a device used for controlled subsurface injection of radioactive
			 tracer material.
(5) "Irretrievable
			 well logging source" means any sealed source containing licensed material that
			 is pulled off or not connected to the wireline that suspends the source in the
			 well and for which all reasonable effort at recovery has been
			 expended.
(6) "Licensed material"
			 means byproduct, source, or special nuclear material received, processed, used,
			 or transferred under a license issued by the Authority under the rules in this
			 chapter.
(7) "Logging assistant"
			 means any individual who, under the personal supervision of a logging
			 supervisor, handles sealed sources or tracers that are not in logging tools or
			 shipping containers or who performs surveys required by
			 333-113-0401.
(8) "Logging Supervisor" means the individual
			 who uses licensed material or provides personal supervision of the use of
			 licensed sources of radiation at the well site and who is responsible to the
			 licensee for assuring compliance with the requirements of Authority rules and
			 the conditions of the license.
(9)
			 "Logging Tool" means a device used subsurface to perform well-logging.
(10) "Mineral Logging" means any
			 logging performed for the purpose of mineral exploration other than oil or
			 gas.
(11) "Personal Supervision"
			 means guidance and instruction by a logging supervisor who is physically
			 present at the jobsite and watching the performance of the operation in such
			 proximity that contact can be maintained and immediate assistance given as
			 required.
(12) "Radioactive Marker"
			 means radioactive material placed subsurface or on a structure intended for
			 subsurface use for the purpose of depth determination or direction orientation.
			 For purposes of these rules, this term includes radioactive collar markers and
			 radioactive iron nails.
(13)
			 "Safety review" means a periodic review provided by the licensee for its
			 employees on radiation safety aspects of well logging. The review may include,
			 as appropriate, the results of internal inspections, new procedures or
			 equipment, accidents or errors that have been observed, and opportunities for
			 employees to ask safety questions.
(14) "Sealed source" means any licensed
			 material that is encased in a capsule designed to prevent leakage or escape of
			 the licensed material
(15) "Source
			 Holder" means a housing or assembly into which a radioactive source is placed
			 for the purpose of facilitating the handling and use of the source in
			 well-logging operations.
(16)
			 "Subsurface Tracer Study" means the release of unsealed license material or a
			 substance tagged with licensed radioactive material for the purpose of tracing
			 the movement or position of the tagged substance in the well-bore or adjacent
			 formation.
(17) "Surface casing for
			 protecting fresh water aquifers" means a pipe or tube used as a lining in a
			 well to isolate fresh water aquifers from the well.
(18) "Temporary Jobsite" means a location
			 where radioactive materials are present for the purpose of performing well
			 logging operations or subsurface tracer studies.
(19) "Tritium neutron generator target
			 source" means a tritium source used within a neutron generator tube to produce
			 neutrons for use in well logging applications.
(20) "Uranium Sinker Bar" means a weight
			 containing depleted uranium used to pull a logging tool down toward the bottom
			 of a well.
(21) "Well" means a
			 drilled hole in which well logging operations and subsurface tracer studies are
			 performed. As used in this division, "well" includes drilled holes for the
			 purpose of oil, gas, mineral, groundwater or geological exploration.
(22) "Well-Logging" means all operations
			 involving the lowering and raising of measuring devices or tools which may
			 contain sources of radiation into well-bores or cavities for the purpose of
			 obtaining information about the well or adjacent formations that are used in
			 oil, gas, mineral, groundwater or geological exploration.
(23) "Wireline" means a cable containing one
			 or more electrical conductors which is used to lower and raise logging tools in
			 the well-bore.
