SAMPLE TRANSPORTATION INSTRUCTIONS
5.4
3 Prior to shipment assure the package and its contents meet the following requirements:
● The contents are authorized for use in the package.
● The package is in good physical condition for transport.
● All locks or required shipping plugs are properly installed and seal wired where required.
● All conditions of the Type B(U) Certificate of Compliance or Type A approval are met.
[10CFR71.87]
NOTE: Quantities of special form radioactive material equal to or greater than
27Ci (1TBq) of Ir-192, 80Ci (3TBq) of Se-75 or 10.8Ci (0.4TBq) of Co-60 must be shipped
in Type B packages. Quantities less than these quantities can be shipped as Type A.
Type A testing documentation must be kept on file for one year after shipment.
● Maintain copies of the most current Type B, Type A and Special Form certification on file.
4 Assure that the source is secured in the proper shielded position in the shipping package
as described in the appropriate operations manual. Perform a pre-shipment inspection
(see Part A of these instructions) and verify conformance to the transport package certificate.
5 As applicable, attach a security seal with an identification mark to the package closure
that serves as a tamper indicator. [49CFR173.412(a)]
6 If the shipping package is to be packaged inside a crate or other outer packaging, the
outer packaging must be strong enough to withstand the normal conditions of transport
and must not reduce the safety of the package. The shipping package must be placed within
the outer package with sufficient blocking to prevent shifting during transportation.
[49CFR173.25]
7 Survey the exterior surfaces of the package and assure that the maximum radiation level
does not exceed 200mRem/hr (2mSv/hr). Survey 1m from the exterior surfaces of the
package and assure that the maximum radiation level does not exceed 10mRem/hr
(0.1mSv/hr). Determine the proper shipping labels to be applied to the package using the
criteria of table 1. [49CFR172.403]
NOTE: If shipping a Type B container inside an overpack or convenience box in the
back of a vehicle, survey and label both the inner Type B package and the overpack.
Placarding the vehicle is dependent on the category of label applied to the overpack
if used. [49CFR173.448]
Table 1
Maximum radiation Maximum radiation
level at surface level at 1m
Radioactive 0.5mRem/hr None
White I (0.005mSv/hr)
Radioactive 50mRem/hr 1.0mRem/hr
Yellow II (0.5mSv/hr) (0.01mSv/hr)
Radioactive 200mRem/hr 10mRem/hr
Yellow III (2mSv/hr) (0.1mSv/hr)
For a package, both the transport index (TI) and the surface radiation level conditions
shall be taken into account in determining which is the appropriate category of
radioactive material label. Where the TI satisfies the condition for one category but the
surface radiation level satisfies the condition for a different category, the package shall
be assigned to the higher category of the two. For this purpose, category White-I shall
be regarded as the lowest category.
The TI is the maximum radiation level measured in mRem/hr at a distance of 1m from
the external surfaces of the package. When recording the TI, the dose rate units of
mRem/hr are not listed, for example a reading of 2mRem/hr (20µSv/hr) would indicate
a TI = 2.0. (Note that the TI is rounded to the nearest tenth value.)
