Class 7 Radioactive Chemicals and Substances Examples |
 |
Class 7 radioactive materials are extremely dangerous and contain radionuclides which emit ionising radiation. Ionising radiation can potentially cause serious risks to human health. Class Description: Radioactive 7 i |
Uranium Medical Isotopes Thorium Plutonium |
 |
Material in which radioactive material is distributed throughout & the average specific activity is: – ≤ 10 -4 A 2/gram for solids – ≤ 10 -5 A 2/gram for liquids. Class Description: Radioactive 7 ii |
Water with tritium concentration |
 |
Radioactive solids which are either consolidated wastes or activated materials meeting the requirements for §173.468. Radioactive radiation which is distributed throughout a solid, collection of solid objects, or solid compact binding agent (concrete, ceramic, etc). Radioactive Material is relatively insoluble or intrinsically contained in a relatively insoluble material so leaching in water will not exceed 0.1 A 2 after 7 days. Must have an average specific activity of ≤ 2 x 10 -3 A 2/g. Class Description: Radioactive 7 iii |
