Types of radiation

Front

What is alpha radiation?

Back

Alpha radiation consists of 2 protons and 2 neutrons (He nucleus) emitted from a radioactive atom.

Front

How can you identify alpha radiation in a nuclear reaction?

Back

You can tell alpha radiation occurred if 2 protons and 2 neutrons are lost from the nucleus.

Front

Rank the types of radiation in order of increasing ability to penetrate matter.

Back

Alpha, beta, gamma.

Front

What is the penetrating power of alpha radiation?

Back

Alpha radiation has the lowest penetrating power, can penetrate only 0.05 mm into the body, and can be stopped by the skin.

Front

What is beta radiation?

Back

Beta radiation consists of high-energy, high-speed electrons or positrons emitted by certain types of radioactive nuclei.

Front

What is gamma radiation?

Back

Gamma radiation is a form of electromagnetic radiation with high energy and high penetrating power.

Front

What is nuclear fusion?

Back

Nuclear fusion is the process where small nuclei combine to form larger nuclei, releasing energy.

Front

What is nuclear fission?

Back

Nuclear fission is the process of splitting a large atomic nucleus into smaller nuclei, accompanied by the release of energy.

Front

Which type of radiation has the highest penetrating power?

Back

Gamma radiation has the highest penetrating power and can penetrate several centimeters of lead or several meters of concrete.

Front

What can stop alpha radiation?

Back

Alpha radiation can be stopped by a sheet of paper or the outer layer of human skin.
