Current through all regulations passed and filed through July 1, 2024
Terms defined in rule
				3701:1-38-01 of the
				Administrative Code shall have the same meaning when used in this chapter
				except terms redefined within a given rule for use within that rule only, and
				additionally, as used in this chapter of the Administrative Code:
(A) "Energy Compensation Source" (ECS) means
			 a small sealed source, with an activity not exceeding 3.7 megabecquerels (one
			 hundred microcuries), used within a logging tool, or other tool components, to
			 provide a reference standard to maintain the tool's calibration when in use.
(B) "Field Station" means a
			 facility where licensed material may be stored or used and from which equipment
			 is dispatched to temporary job sites.
(C) "Fresh Water Aquifer", for the purpose of
			 this chapter, means a geologic formation that is capable of yielding fresh
			 water to a well or spring.
(D)
			 "Injection Tool" means a device used for controlled subsurface injection of
			 radioactive tracer material.
(E)
			 "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.
(F) "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 rule
			 3701:1-49-21 of
			 the Administrative Code.
(G)
			 "Logging Supervisor" means an individual who uses licensed material or provides
			 personal supervision in the use of licensed material at a temporary job site
			 and who is responsible to the licensee for assuring compliance with the
			 requirements of Chapter 3748. of the Revised Code and rules promulgated
			 thereunder and the conditions of the license.
(H) "Logging Tool" means a device used
			 subsurface to perform well logging.
(I) "Personal Supervision" means guidance and
			 instruction by a logging supervisor, who is physically present at a temporary
			 job site, who is in personal contact with logging assistants, and who can give
			 immediate assistance.
(J)
			 "Radioactive Marker" means licensed material used for depth determination or
			 direction orientation. For purposes of this chapter, this term includes
			 radioactive collar markers and radioactive iron nails.
(K) "Reasonable Effort" means effort
			 commensurate with an assessment, performed by the licensee and approved by the
			 department, of the health and safety risks of a lost source considering the
			 geological and hydrological location of the source, the source type, and risks
			 and costs of attempted source retrieval.
(L) "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.
(M) "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.
(N) "Subsurface Tracer Study" means the
			 release of unsealed licensed material or a substance labeled with licensed
			 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.
(O) "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.
(P) "Temporary Job Site" means a place where
			 licensed materials are present for the purpose of performing well logging or
			 subsurface tracer studies.
(Q)
			 "Tritium Neutron Generator Target Source" means a tritium source used within a
			 neutron generator tube to produce neutrons for use in well logging
			 applications.
(R) "Uranium Sinker
			 Bar" means a weight containing depleted uranium used to pull a logging tool
			 toward the bottom of a well.
(S)
			 "Well" means a drilled hole in which well logging may be performed. As used in
			 this chapter, "well'' includes drilled holes for the purpose of oil, gas,
			 mineral, groundwater, or geological exploration.
(T) "Well Logging" means all operations
			 involving the lowering and raising of measuring devices or tools which contain
			 licensed material or are used to detect licensed materials 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.
