Current through Register 2024 Notice Reg. No. 28, July 12, 2024
(a) The definitions in
						section 30100 apply to this article.
(b) As used in this article:
(1) "Energy compensation source" means a small
						sealed source (not exceeding an activity of 100 microcuries), used within a 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 licensed radioactive material or radiation
						machines may be stored or used and from which equipment is dispatched to temporary
						jobsites;
(3) "Fresh Water Aquifer"
						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 radioactive 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) "Logging assistant" means any individual who,
						under the personal supervision of a logging supervisor, handles radiation sources
						that are not in logging tools or shipping containers or who performs surveys
						required by section
						30348.4;
(7) "Logging supervisor" means any individual who
						uses radiation sources or provides personal supervision in the use of radiation
						sources at a temporary jobsite and who is responsible to the user for assuring
						compliance with the requirements of this regulation and the conditions of the
						license;
(8) "Logging tool" means a
						device used subsurface to perform well logging;
(9) "Personal supervision" means guidance and
						instruction by a logging supervisor who is physically present at a temporary
						jobsite, who is in personal contact with logging assistants, and who can give
						immediate assistance;
(10) "Radioactive
						marker" means radioactive material used for depth determination or direction
						orientation. The term includes radioactive collar markers and radioactive iron
						nails;
(11) "Safety review" means a
						periodic review provided by the user for its employees on radiation safety as it
						relates to 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 safety questions by employees;
(12) "Source holder" means a housing or assembly
						into which a sealed source is placed to facilitate the handling and use of the
						source in well logging;
(13) "Subsurface
						tracer study" means the release of unsealed radioactive material or a substance
						labeled with radioactive material in a single well for the purpose of tracing the
						movement or position of the material or substance in the well or adjacent
						formation;
(14) "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;
(15) "Temporary jobsite" means a place where
						licensed radioactive materials or radiation machines are present for the purpose of
						performing well logging or subsurface tracer studies;
(16) "Tritium neutron generator target source"
						means a tritium source used within a neutron generator tube to produce neutrons for
						use in well logging applications;
(17)
						"Uranium sinker bar" means a weight containing depleted uranium used to pull a
						logging tool towards the bottom of a well;
(18) "Well" means a drilled hole in which well
						logging may be performed and includes drilled holes for the purpose of oil, gas,
						mineral, groundwater, or geological exploration;
(19) "Well logging" means all operations involving
						the lowering and raising of measuring devices or tools which contain radiation
						sources or are used to detect radiation sources in wells for the purpose of
						obtaining information about the well or adjacent formations which may be used in
						oil, gas, mineral, groundwater, or geological exploration;
(20) "Wireline" means a cable containing one or
						more electrical conductors, which is used to lower and raise logging tools in the
						well-bore.
