				  accordance with the procedure prescribed in LAC 33:XV.1599.B-F.
A2
- the maximum
				  activity of radioactive material, other than special form, low specific
				  activity (LSA), and surface contaminated object (SCO) material, permitted in a
				  Type A package. This value is listed in 10 CFR Part 71, Appendix A, Table A-1,
				  A-2, A-3, or A-4, incorporated by reference in LAC 33:XV.1599.A, or may be
				  derived in accordance with the procedure prescribed in LAC
				  33:XV.1599.B-F.
Carrier
- 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.
Certificate Holder
- a person who has been
				  issued a certificate of compliance or other package approval by the U.S.
				  NRC.
Certificate of Compliance (CoC)
- the
				  certificate issued by the U.S. NRC that approves the design of a package for
				  the transportation of radioactive material.
Close Reflection by Water
- immediate
				  contact by water of sufficient thickness for maximum reflection of
				  neutrons.
Consignment
- each shipment of a package or
				  groups of packages or load of radioactive material offered by a shipper for
				  transport.
Contamination
-the presence of a radioactive
				  substance on a surface in quantities in excess of 0.4
				  Bq/cm2 (1 x 105
				  [MICRO]Ci/cm2) for beta and gamma emitters and low
				  toxicity alpha emitters, or 0.04 Bq/cm2 (1 x
				  106 [MICRO]Ci/cm2) for
				  all other alpha emitters.
a.
Fixed Contamination
-contamination that cannot be removed from
				a surface during normal conditions of transport.
b.
Non-Fixed
				Contamination
-contamination that can be removed from a surface during
				normal conditions of transport.
Containment System
- the assembly of
				  components of the packaging intended to retain the radioactive material during
				  transport.
Conveyance
- for transport by public highway
				  or rail, any transport vehicle or large freight container; 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 for transport by

Criticality Safety Index (CSI)
-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 LAC 33:XV.1511 and 1512 and in
				  10 CFR
				  71.59. The
criticality safety
				  inde
x 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.

				  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.

				  maximum gauge pressure that would develop in the containment system in a period
				  of one year under the heat condition specified in
				  10 CFR
				  71.71(c)(1), in the absence
				  of venting, external cooling by an ancillary system, or operational controls
				  during transport.

				  occurring distribution of thorium isotopes (essentially 100 weight percent
				  thorium-232).

-
				  radioactive material which has not been demonstrated to qualify as special form
				  radioactive material.

				  such an extent that the maximum nuclear reactivity results.
Package
- the packaging together with its
				  radioactive contents as presented for transport.
a.
Fissile Material Package, Type AF
				Package, Type BF Package, Type B(U)F Package, or Type B(M)F Package
- a
				fissile material packaging together with its fissile material
				contents.
b.
Type A
				Package

Type A package
is defined and must comply with the U.S. DOT
				regulations in   49 CFR Part 173.
c.
Type B Package
- a Type B
				packaging together with its radioactive contents. On approval, a
Type B
				package
design is designated by the NRC as B(U) unless the package has
				a maximum normal operating pressure of more than 700 kPa (100

				allow the release of radioactive material to the environment under the tests
				specified in
				10 CFR
				71.73 (hypothetical accident conditions), in
				which case it will receive a designation B(M). B(U) refers to the need for
				unilateral approval of international shipments; B(M) refers to the need for
				multilateral approval of international shipments. There is no distinction made
				in how packages with these designations may be used in domestic transportation.
				To determine their distinction for international transportation, see U.S. DOT
				regulations in 49 CFR Part 173. A
Type B package

				before September 6, 1983, was designated only as Type B. Limitations on its use
				are specified in
				10 CFR
				71.19.
Packaging
