Alpha, Beta and Gamma Radiation

Front

What is Alpha Radiation?

Back

Alpha radiation consists of alpha particles, which are made up of 2 protons and 2 neutrons. It is the least penetrating type of radiation.

Front

What is Beta Radiation?

Back

Beta radiation consists of beta particles, which are 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, similar to X-rays, and is the most penetrating type of radiation.

Front

Which type of radiation is the most ionizing?

Back

Alpha radiation is the most ionizing type of radiation.

Front

What is the structure of an alpha particle?

Back

An alpha particle is made up of 2 protons and 2 neutrons.

Front

What happens to the mass number in alpha decay?

Back

In alpha decay, the mass number decreases by 4.

Front

What material can absorb beta radiation?

Back

Which type of radiation is the most penetrating?

Back

Gamma radiation is the most penetrating type of radiation.

Front

What is the charge of an alpha particle?

Back

An alpha particle has a positive charge due to its 2 protons.

Front

What is the charge of a beta particle?

Back

A beta particle can have a negative charge (electron) or a positive charge (positron).
