Study Notes
Ionizing Radiation
- Alpha particles have 2 neutrons and 2 protons, travel short distances, and have a large mass.
Radiation Formation
- Beta particles are formed through a process where a neutron in an unstable atom is converted into a proton and an electron, with the electron being emitted as a beta particle.
X-Ray Generation
- X-rays are typically generated when high-energy electrons are suddenly stopped or decelerated, resulting in the emission of electromagnetic radiation.
Unstable Atoms
- Unstable atoms emit ionizing radiation due to having excess energy or mass, which they release to become stable.
Stable vs Unstable Atoms
- The primary difference between stable and unstable atoms is that stable atoms do not emit ionizing radiation, whereas unstable atoms do.
Gamma Radiation
- Gamma radiation consists of high-energy photons and does not consist of particles like alpha or beta particles.
Alpha Radiation
- Alpha particles are characterized by being heavy, consisting of 2 neutrons and 2 protons.
High-Energy Radiation
- Gamma radiation contains more energy than ultraviolet, infrared, radio waves, microwaves, or visible light.
Non-Ionizing Radiation
- The main characteristic of non-ionizing radiation is that it is unable to disrupt atoms and molecules, and therefore does not lead to the formation of ions and free radicals.
Ionizing Radiation
- Ionizing radiation is defined as radiation that is able to disrupt atoms and molecules, leading to the formation of ions and free radicals.
Test your knowledge on the primary types of ionizing radiation, including alpha particles, beta particles, and gamma rays. Learn about radiation that has enough energy to eject electrons from atoms or molecules in the irradiated medium.
