Class 7

Class 7 - Radioactive material is for material that spontaneously and continually emits certain types of radiation that can be harmful to your health. Common examples include x-ray machines or isotopes used for medical or industrial purposes like Cobalt 60 and Iodine 132.

Radioactive material is divided into the following categories. These categories are determined by the transport index and indicate the required label.

Category I - White includes radioactive materials with low dose rates on the package surface. No transport index is required.

Category II - Yellow includes radioactive materials with dose rates that are higher than Category I and have a transport index that does not exceed 1.

Category III - Yellow includes radioactive materials with dose rates that are higher than Category II or have a transport index that exceeds 1 but does not exceed 10.

Fissile materials include Uranium 233 and 235 and Plutonium 239 and 241. Fissile materials also require Criticality Safety Index labels in addition to the appropriate radioactive labels.
