Uses of Radioisotopes in Industry

What is the primary difference between stable and unstable isotopes?

• Stable isotopes are radioactive.

• Unstable isotopes undergo radioactive decay.

• Unstable isotopes do not undergo decay.

• Stable isotopes emit radiation.

How do radioisotopes help in monitoring the content of canned food?

• By using detectors to measure radiation levels.

• By increasing the shelf life of the food.

• By altering the taste of the food.

• By changing the color of the food.

What happens to the detector reading if the canned food content is less than required?

• The reading will fluctuate randomly.

• The reading will remain unchanged.

• The reading will be higher.

• The reading will be lower.

In what way are radioisotopes used to detect underground pipe leaks?

• By sealing the leak with radioactive material.

• By adding radioisotopes to the water and using detectors.

• By increasing the water pressure.

• By changing the color of the water.

How can radioisotopes help in determining the wear rate of engine components?

• By coating the engine with a protective layer.

• By measuring the amount of radioactive substance in the engine oil.

• By increasing the engine's fuel efficiency.

• By reducing the engine temperature.
