Class 7 Radioactive Material Hazmat

Class 7 Radioactive Material

7.1 Radioactive material means any material containing radionuclides where both the activity concentration and the total activity in the consignment exceed the values.

7.1.1 The following radioactive materials are not included in class 7 for the purposes of this Code:

(a) radioactive material that is an integral part of the means of transport;

(b) radioactive material moved within an establishment which is subject to appropriate safety regulations in force in the establishment and where the movement does not involve public roads or railways;

(d) radioactive material in consumer products which have received regulatory approval, following their sale to the end user;

(e) natural material and ores containing naturally occurring radionuclides which are not intended to be processed for use of these radionuclides provided the activity concentration of the material does not exceed 10 times the values specified.

7.2 Packages and overpacks should be assigned to either category I - WHITE, II - YELLOW or III - YELLOW in accordance with the conditions specified in the table hereunder and with the following provisions:

(a) For a package or overpack, both the transport index and the surface radiation level conditions should be taken into account in determining which is the appropriate category. Where the transport index satisfies the condition for one category but the surface radiation level satisfies the condition for a different category, the package or overpack should be assigned to the higher category. For this purpose, category I - WHITE should be regarded as the lowest category.

(b) The transport index should be determined following the procedures specified.

(c) If the surface radiation level is greater than 2 mSv/h, the package or overpack should be transported under exclusive use and under the provisions as appropriate.

(d) A package transported under a special arrangement should be assigned to category III - YELLOW.

(e) An overpack which contains packages transported under special arrangement should be assigned to category III - YELLOW.

CATEGORIES OF PACKAGES AND OVERPACKS
Conditions		Category
Transport index	Maximum radiation level at any point on external surface
0^a	Not more than 0.005 mSv/h	I - WHITE
More than 0 but not	More than 0.005 mSv/h but not	II - YELLOW
more than 1^a	more than 0.5 mSv/h
More than 1 but not more than 10	More than 0.5 mSv/h but not more than 2 mSv/h	III - YELLOW
More than 10	More than 2 mSv/h but not more than 10 mSv/h	III - YELLOW^b

^a If the measured TI is not greater than 0.05, the value quoted may be zero. ^b Should also be transported under exclusive use.

Fissile Label:

Applied to packages that contain fissile materials. The Criticality Safety Index (CSI) for each package will not be noted on the label. The CSI is displayed on the label to assist the shipper in controlling how many fissile packages can be grouped together on a conveyance. When applicable, the fissile label will appear adjacent to the radioactive material label.
