Radioactive Waste Characteristics and Management

The video explains radioactive waste, which includes any material containing radioactive substances with no foreseeable use. It categorizes waste into four classes: uranium mine and mill waste, low level, intermediate level, and high level radioactive waste. Each class has specific characteristics, sources, and containment requirements. The Canadian Nuclear Safety Commission regulates these wastes to ensure public and environmental safety.

What is the primary characteristic of radioactive waste?

• It is always safe to handle without precautions.

• It is only found in gaseous form.

• It contains a radioactive nuclear substance with no foreseeable use.

• It is always in liquid form.

Which of the following is NOT a class of radioactive waste in Canada?

• Uranium mine and mill waste

• Low level radioactive waste

• Recyclable radioactive waste

• Intermediate level radioactive waste

What materials are included in uranium mine and mill waste?

• Ion exchange resins

• Decommissioned parts

• Tailings and waste rock

• Used nuclear fuel

Which facilities produce low level radioactive waste?

• Nuclear power plants and research reactors

• Solar power plants

• Hydroelectric dams

• Wind farms

What is a characteristic of intermediate level radioactive waste?

• It is safe to dispose of in regular landfills.

• It contains long-lived radionuclides.

• It does not require isolation.

• It is only produced by uranium mines.

What form can low level radioactive waste take?

• Solar panels

• Used equipment and clothing

• Natural gas

• Fresh nuclear fuel

Which type of waste requires isolation for longer than several hundred years?

• Uranium mine and mill waste

• Intermediate level radioactive waste

• Low level radioactive waste

• Recyclable waste

What is the primary component of high level radioactive waste?

• Decommissioned parts

• Ion exchange resins

• Used nuclear fuel

• Tailings

Which organization regulates radioactive waste in Canada?

• Canadian Nuclear Safety Commission

• Canadian Environmental Protection Agency

• Canadian Space Agency

• Canadian Food Inspection Agency

What is required for the containment of high level radioactive waste?

• Immediate recycling

• No special containment

• Long-term isolation

• Short-term storage
