Types of Radiation & Nuclear Reactions

Front

What is fission?

Back

Fission is the process of splitting a nucleus into smaller nuclei, releasing a significant amount of energy.

Front

What type of radiation is emitted when an unstable nucleus loses an electron?

Back

Beta radiation is emitted when an unstable nucleus loses an electron.

Front

What is alpha radiation?

Back

Alpha radiation consists of helium nuclei (2 protons and 2 neutrons) emitted from a radioactive source.

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 of high frequency and energy, emitted from a radioactive nucleus.

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 is radioactive decay?

Back

Radioactive decay is the process by which an unstable atomic nucleus loses energy by emitting radiation.

Front

What is the difference between alpha, beta, and gamma radiation?

Back

Alpha radiation consists of heavy particles, beta radiation consists of electrons or positrons, and gamma radiation consists of electromagnetic waves.

Front

What is a common use of gamma radiation?

Back

Gamma radiation is commonly used in medical treatments, such as cancer radiotherapy, and in sterilizing medical equipment.

Front

What is the significance of half-life in radioactive decay?

Back

Half-life is the time required for half of the radioactive atoms in a sample to decay, indicating the stability of the isotope.
