1. Radioisotopes are often used in:

nuclear power plants

pharmacology (the study of medicines and drugs)

agricultural studies

all of these industries
2. The most common use of radioisotopes in medicine is for diagnosis of illness.

TRUE

FALSE

3. Why is nuclear waste enclosed in lead and cement casks and buried deep under ground?

The cement makes the nuclear material inert.

The lead, cement and deep earth cover act as radiation shields.

The cement reacts with the waste to initiate the nuclear process.

The cement takes on the properties of the fuel, creating more fuel.

4. All of the radioactive storage locations in the United States are located in either Nevada or Utah.

TRUE

FALSE

5. Radioactive contamination can enter the body only through absorption.

TRUE

FALSE


6. The main advantage of using uranium fuel over coal is that uranium is more efficiently burned.

TRUE

FALSE


7. If it could be controlled, nuclear fusion would be a cleaner, more efficient way to create more nuclear power.

TRUE

FALSE

8. Nuclear energy is considered an alternative energy because it is renewable, does not pollute the environment, and reduces carbon dioxide emissions.

TRUE

FALSE


9. Why are nuclear power plants are favored for producing energy over other power facilities?

1. Radio isotopes are used in all the industries mentioned above, that is, nuclear power plants, pharmacology and agricultural studies. So the correct option is D.
2. The statement is true. Radio isotope is used in medicine mostly as a diagnostic tool to diagnose illnesses. 
3. Nuclear wastes are enclosed in lead and buried in cement casks deep underground so that the lead, cement and the earth cover will act as radiation shield. The correct option is B. 
4.This statement is false. The US has 75 different radioactive storage locations across USA.
5. This statement is false. Radioactive contamination can enter the body through inhalation, ingestion, absorption and through contact with skin or clothing materials.
6. The statement is false. Uranium fuel is not burned, it undergoes fission process. 
7. This statement is true. This is because nuclear power production has less green house effects compare to fossils fuels.
8. This statement is false. Nuclear energy is not renewable and it pollutes the environment.
9. Nuclear power plants are favoured because the power produce by them are more reliable source of energy which does not deplete the ozone layer.
