Radiation

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 alpha particles?

Back

Alpha particles are positively charged particles consisting of two protons and two neutrons, emitted during alpha decay.

Front

What happens during alpha decay?

Back

During alpha decay, an atomic nucleus emits an alpha particle, resulting in a new element with a lower atomic number.

Front

What is the penetrating power of alpha particles?

Back

Alpha particles have low penetrating power and can be stopped by a sheet of paper or the outer layer of human skin.

Front

What is the order of radiation types from most to least penetrating?

Back

Gamma, Beta, Alpha.

Front

What is a beta particle?

Back

A beta particle is a high-energy, high-speed electron or positron emitted during beta decay.

Front

What is gamma radiation?

Back

Gamma radiation is a form of electromagnetic radiation of high frequency and energy, emitted from the nucleus of an atom.

Front

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

Back

Alpha radiation consists of helium nuclei, beta radiation consists of electrons or positrons, and gamma radiation consists of electromagnetic waves.

Front

What is a nuclear reaction?

Back

A nuclear reaction is a process in which two nuclei or nuclear particles collide, resulting in the transformation of elements.

Front

What is the significance of the atomic number in nuclear reactions?

Back

The atomic number determines the identity of an element and changes during nuclear reactions, affecting the resulting elements.
