1. Radioisotopes can’t be formed nohen radiation that result from the explosion influenced atoms nearly.

2. Underground testing can’t climinate fallout.

3. Not all nuclear explosions produce a giant fireball of intensely hot gases.

4. Fallout particles range in size from line imbisible clust to ask of snowflake size.

5. In general, the intensity of radiation in an area decreases as the distance from the blast site decreases too.

6. Local fallout may settle over a smoothly shaped are, depending upon the winds that carry it.

7. In the most powerful nuclear exposions, much of the fallout may rise to the troposphere.

8. The radioisotopes in fallout give off radioation for definite periods of time.

9. Most of the fallout alements continue to give off radion over a long period.

10. The possibility of nuclear roar has caused people to think about the danger of distant fallout.

11. There is no danger that certain fallot elements may enter the human body through breathing and eating.

12. Subway- train tunnels or other underground areas aren’t designated as public fallout shelters.

30. Match the words in the left column with their explanation in the right column:

Explosion	Is a ball of fire, e.g. one at the centre of a nuclear explosion?
Eliminate	An intensely burning fire or an active burning
Fission	A violent expansion, usually accompanied by noise, caused by a sudden release of energy from a very rapid chemical or nuclear reaction.
Fallout	The remnants of something broken to pieces
Precipitation	Means to remove something completely, especially when it something that you do not want or need.
Decay	Is the splitting of the nucleus of an atom to produce a large amount of energy or cause a large explosion?
Blaze	The often radioactive particles stirred up by or resulting from a nuclear explosion and descending through the atmosphere
Defies	Is a process in a chemical reaction which causes solid particles to become separation from a liquid?
Fireball	To decrease gradually in quantity, activity, or force.
