Questions and Answers
What is radiation?
What is radiation?
The emission of energy as electromagnetic waves or as moving subatomic particles, especially high-energy particles which may cause ionization.
What is ionization?
What is ionization?
Ionization is the process by which an atom or a molecule acquires a negative or positive charge by gaining or losing electrons to form ions.

Study Notes
Radiation
- Emission of energy as electromagnetic waves or high-energy subatomic particles.
- Ionizing radiation can lead to the production of ions by influencing atoms and molecules.
Ionization
- Process of an atom or molecule acquiring a charge through electron gain or loss.
- Resulting ions can be due to exposure to specific types of radiation.
Alpha Particles
- Comprise two protons and two neutrons; equivalent to a Helium nucleus.
- Carry a charge of +2, with strong interaction with matter.
- Travel slowly and have limited penetration ability through substances.
Beta Particles
- High-energy, high-speed electrons or positrons emitted during beta decay.
- More penetrating and faster than alpha particles, allowing deeper material interaction.
Gamma Radiation
- Consists of gamma rays which are electromagnetic radiation with extremely high frequency.
- Composed of high-energy photons and categorized as ionizing radiation, posing biological hazards.
Inverse Square Law
- Intensity of phenomena (gravitational force, light, radiation) diminishes with the square of the distance from the source.
- Underlines the principle that as distance increases, intensity decreases dramatically.
Radiation Sickness
- Illness resulting from exposure to ionizing radiation; notably Gamma Radiation.
- Symptoms include nausea, hair loss, diarrhea, bleeding, and damage to bone marrow and central nervous system.
