Radiation Types and Applications

Front

What is radiation?

Back

Radiation is the emission of energy as electromagnetic waves or as moving subatomic particles, especially high-energy particles that cause ionization.

Front

What are the main types of radiation?

Back

The main types of radiation are alpha particles, beta particles, gamma rays, and neutron radiation.

Front

What is alpha decay?

Back

Alpha decay is a type of radioactive decay in which an atomic nucleus emits an alpha particle, consisting of 2 protons and 2 neutrons, resulting in a new element.

Front

What is beta decay?

Back

Beta decay is a type of radioactive decay in which a beta particle (an electron or a positron) is emitted from an atomic nucleus, transforming a neutron into a proton or vice versa.

Front

What is gamma radiation?

Back

Gamma radiation is a form of electromagnetic radiation of high energy and short wavelength, emitted from the nucleus of a radioactive atom.

Front

What is nuclear fusion?

Back

Nuclear fusion is a process where two light atomic nuclei combine to form a heavier nucleus, releasing a significant amount of energy.

Front

What is nuclear fission?

Back

Nuclear fission is a process in which a heavy atomic nucleus splits into two or more smaller nuclei, along with the release of energy.

Front

What is the role of neutrons in nuclear reactions?

Back

Neutrons play a crucial role in nuclear reactions by initiating fission in heavy nuclei and stabilizing the nucleus.

Front

What is a half-life?

Back

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

Front

What is a radioactive isotope?

Back

A radioactive isotope is an isotope of an element that has an unstable nucleus and emits radiation as it decays.
