Types of Radioactive Decay

Front

What is Gamma Decay?

Back

Gamma decay is a type of radioactive decay where a nucleus emits a high-energy wave, often resulting in the release of gamma radiation. It can penetrate through the human body and is stopped by thick walls of water, concrete, or lead.

Front

What is Alpha Decay?

Back

Alpha decay is a type of radioactive decay where an unstable nucleus emits an alpha particle, which consists of 2 protons and 2 neutrons. It is the weakest type of radiation and can be stopped by a piece of paper or human skin.

Front

What is Beta Decay?

Back

Beta decay is a type of radioactive decay in which a nucleus emits a beta particle, which can be an electron or a positron. This process occurs when a neutron is transformed into a proton or vice versa.

Front

What type of radiation can be stopped by a piece of paper?

Back

Alpha Decay can be stopped by a piece of paper or human skin.

Front

What type of radiation can penetrate the human body?

Back

Gamma Decay can penetrate the human body and requires thick barriers like water, concrete, or lead to be stopped.

Front

Why do atoms undergo radioactive decay?

Back

Atoms undergo radioactive decay to become more stable when they have an unstable nucleus.

Front

What is the symbol for Alpha Decay?

Back

The symbol for Alpha Decay is 'α'.

Front

What is the strongest type of radiation?

Back

Gamma Decay is considered the strongest type of radiation due to its high energy and penetrating power.

Front

What is the difference between Alpha and Beta Decay?

Back

Alpha decay emits alpha particles (2 protons and 2 neutrons), while beta decay emits beta particles (electrons or positrons) as a result of neutron-to-proton conversion.

Front

What is a common use of Gamma Radiation?

Back

Gamma radiation is commonly used in medical treatments, such as cancer radiotherapy, and in imaging techniques.
