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) "Carrier" means a person engaged in the
		  transportation of passengers or property by land or water as a common,
		  contract, or private carrier, or by civil aircraft.
(B) "Certificate holder" means a person who has been
		  issued a certificate of compliance or other package approval by the United
		  States nuclear regulatory commission.
(C) "Certificate of compliance (CoC)" means the
		  certificate issued by the United States nuclear regulatory commission under
		  subpart D of 10 C.F.R. 71 (as in effect on the effective date of this rule)
		  which approves the design of a package for the transportation of radioactive
		  material.
(D)  "Closed transport vehicle" means a transport
		  vehicle equipped with a securely attached exterior enclosure that during normal
		  transportation restricts the access of unauthorized persons to the cargo space
		  containing the radioactive material. The enclosure may be temporary or
		  permanent but shall limit access from top, sides, and ends. In the case of
		  packaged materials, it may be of the "see-through" type.
(E) "Close reflection by water" means immediate contact
		  by water of sufficient thickness for maximum reflection of
		  neutrons.
(F) "Consignment" means each
		  shipment of a package or groups of packages or load of radioactive material
		  offered by a shipper for transport.
(G) "Containment system" means
		  the assembly of components of the packaging intended to retain the radioactive
		  material during transport.
(H) "Contamination" means the
		  presence of a radioactive substance on a surface in quantities in excess of 0.4
		  becquerel per square centimeter (1x10-5microcurie per square centimeter) for beta
		  and gamma emitters and low toxicity alpha emitters, or 0.04 becquerel per
		  square centimeter (1x10-6microcurie per square centimeter) for all
		  other alpha emitters.
(1) Fixed contamination
			 means contamination that cannot be removed from a surface during normal
			 conditions of transport.
(2) Non-fixed
			 contamination means contamination that can be removed from a surface during
			 normal conditions of transport.
(I)  "Conveyance" means:
(1) For transport by public highway or
			 rail, any transport vehicle or large freight container;
(2) For transport by water, any vessel,
			 or any hold, compartment, or defined deck area of a vessel including any
			 transport vehicle on board the vessel; and
(3) For transport by air, any
			 aircraft.
(J) "Criticality safety index (CSI)" means the
		  dimensionless number (rounded up to the next tenth) assigned to and placed on
		  the label of a fissile material package, to designate the degree of control of
		  accumulation of packages, overpacks or freight containers containing fissile
		  material during transportation. Determination of the criticality safety index
		  is described in rules 3701:1-50-11 and 3701:1-50-12 of the Administrative Code
		  and 10 C.F.R. 71.59 (as in effect on the effective date of this rule). The
		  criticality safety index for an overpack, freight container, consignment or
		  conveyance containing fissile material packages is the arithmetic sum of the
		  criticality safety indices of all the fissile material packages contained
		  within the overpack, freight container, consignment or conveyance.
(K) "Deuterium" means, for the purpose of rules
		  3701:1-50-11 and 3701:1-50-13 of the Administrative Code, deuterium and any
		  deuterium compounds, including heavy water, in which the ratio of deuterium
		  atoms to hydrogen atoms exceeds one to five thousand.
(L)  "DOT" means United States department of
		  transportation.
(M) "Enriched uranium" means uranium containing more
		  uranium-235 than the naturally occurring distribution of uranium
		  isotopes.
(N)  "Exclusive use" means the sole use by a single
		  consignor of a conveyance for which all initial, intermediate, and final
		  loading and unloading are carried out in accordance with the direction of the
		  consignor or consignee. The consignor and the carrier must ensure that any
		  loading or unloading is performed by personnel having radiological training and
		  resources appropriate for safe handling of the consignment. The consignor must
		  issue specific instructions, in writing, for maintenance of exclusive use
		  shipment controls, and include them with the shipping paper information
		  provided to the carrier by the consignor.
(O) "Graphite" means, for the purposes of rules
		  3701:1-50-11 and 3701:1-50-13 of the Administrative Code, graphite with a boron
		  equivalent content less than five parts per million and density greater than
		  1.5 grams per cubic centimeter.
(P) "Indian tribe" means an Indian or Alaska native
		  tribe, band, nation, pueblo, village, or community that the secretary of the
		  interior acknowledges to exist as an Indian tribe pursuant to the Federally
		  Recognized Indian Tribe List Act of 1994, Pub.L. No. 103-454, 108 Stat. 4791,
		  25 U. S. C. 5130 (as in effect on the effective date of this
		  rule).
(Q)  "Low toxicity alpha emitters" means natural
		  uranium, depleted uranium, natural thorium, uranium-235, uranium-238,
		  thorium-232, thorium-228 or thorium-230 when contained in ores or physical or
		  chemical concentrates or tailings; or alpha emitters with a half-life of less
		  than ten days.
(R) "Maximum normal operating pressure" means the
		  maximum gauge pressure that would develop in the containment system in a period
		  of one year under the heat condition specified in 10 C.F.R. 71.71(C)(1) (as in
		  effect on the effective date of this rule), in the absence of venting, external
		  cooling by an ancillary system, or operational controls during
		  transport.
(S) "Natural thorium" means thorium with the naturally
		  occurring distribution of thorium isotopes or one hundred weight per cent
		  thorium-232.
(T)  "Natural uranium" means uranium (which may be
		  chemically separated) with the naturally occurring distribution of uranium
		  isotopes (approximately 0.711 weight per cent uranium-235, and the remainder by
		  weight essentially uranium-238).
(U) "Optimum interspersed hydrogenous moderation" means
		  the presence of hydrogenous material between packages to such an extent that
		  the maximum nuclear reactivity results.
(V) "Specific activity of a radionuclide" means
		  the radioactivity of the radionuclide per unit mass of that nuclide. The
		  specific activity of a material in which the radionuclide is essentially
		  uniformly distributed is the radioactivity per unit mass of the
		  material.
(W) "Spent nuclear fuel or spent fuel" means fuel
		  that has been withdrawn from a nuclear reactor following irradiation, has
		  undergone at least one year's decay since being used as a source of energy
		  in a power reactor, and has not been chemically separated into its constituent
		  elements by reprocessing. Spent fuel includes the special nuclear material,
		  byproduct material, source material, and other radioactive materials associated
		  with fuel assemblies.
(X) "State" means a state of the United States,
		  the District of Columbia, the Commonwealth of Puerto Rico, the Virgin Islands,
		  Guam, American Samoa, and the Commonwealth of the Northern Mariana
		  Islands.

		  individual that represents tribal leadership of an Indian tribe, such as the
		  chief, president, or tribal council leadership.
(Z) "Unirradiated uranium" means uranium
		  containing not more than two thousand becquerels (fifty-four nanocuries) of
		  plutonium per gram of uranium-235, not more than nine megabecquerels (two
		  hundred forty-three microcuries) of fission products per gram of uranium-235,
		  and not more than 0.005 grams of uranium-236 per gram of
		  uranium-235.
