Current through Register 1525, July 5, 2024
The following terms are as defined here for the purpose of
				  105 CMR
				  120.770. To ensure compatibility with
				  international transportation standards, all limits in this part are given in
				  terms of dual units: The International System of Units (SI) followed or
				  preceded by U.S. standard or customary units. The U.S. customary units are not
				  exact equivalents but are rounded to a convenient value, providing a
				  functionally equivalent unit. For the purpose of
				  105 CMR
				  120.770, either unit may be used.
A
1 means the
				  maximum activity of special form radioactive material permitted in a Type A
				  package. This value is either listed in
				  105 CMR
				  120.798:
Appendix A
, Table
				  A-1, or may be derived in accordance with the procedures prescribed in
				  105 CMR
				  120.798:
Appendix A
.
A
2 means the
				  maximum activity of radioactive material, other than special form material,
				  LSA, and SCO material, permitted in a Type A package. This value is either
				  listed in
				  105 CMR
				  120.798:
Appendix A
, Table
				  A-1, or may be derived in accordance with the procedures prescribed in
				  105 CMR
				  120.798:
Appendix A
.

				  is described in
				  105
				  CMR 120.781 and
				  120.782, and
				  10 CFR
				  71.59. 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.

				  source, byproduct or special nuclear material required to be in US Nuclear
				  Regulatory Commission-approved specification packaging while transported to,
				  through or across a state boundary to a disposal site, or to a collection point
				  for transport to a disposal site.
Package
means the packaging together
				  with its radioactive contents as presented for transport.
(1) Fissile material package or Type AF package, Type BF
				  package, Type B(U)F package, or Type B(M)F package means a fissile material
				  packaging together with its fissile material contents.
(2) Type A package means a Type A packaging together with its
				  radioactive contents. A Type A package is defined and must comply with the DOT
				  regulations in 49 CFR Part 173 .
(3) Type B package means a Type B packaging together with its

				  device that would 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 DOT
				  regulations in 49 CFR Part 173. A Type B package approved before September 6,
				  1983, was designated only as Type B. Limitations on its use are specified in
