Front

Define alpha radiation.

Back

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

Front

Define beta radiation.

Back

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

Front

Define gamma radiation.

Back

Gamma radiation is a form of electromagnetic radiation of high frequency and energy, emitted from radioactive decay.

Front

What is the charge of an alpha particle?

Back

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

Front

What is the charge of a beta particle?

Back

A beta particle can be either negatively charged (electron) or positively charged (positron).
