2 Types of Ionizing Radiation

1. Directly Ionizing Radiation 2. Indirectly Ionizing Radiation

type of ionizing radiation that * Includes charged particles that have enough energy to remove electrons or ionize molecules. * Can cause multiple ionization events.

Directly Ionizing Radiation

Type of ionizing radiation that * Includes uncharged particles such as photons or neutrons. * Occurs from an ionization that sets free a single electron with insufficient energy to produce multiple ionization events.

Indirectly Ionizing Radiation

2 Basic Types of Radiation

Particulate Radiation Electromagnetic Radiation

Basic type of radiation that has * Charged subatomic particles (alpha and beta radiation). * Subatomic particles carry energy and have mass.

Particulate Radiation

* Primarily produced during radioactivity of an unstable atom. * Must be in motion and possess sufficient kinetic energy to cause ionization.

Particulate radiation

Type of Particulate Radiation that is * Equivalent to a Helium nucleus (Consists of 2 protons and 2 neutrons). * Atomic mass is approximately 4 amu. * Large and exerts great electrostatic force. * Emitted only from heavy elements

Alpha Radiation

Type of Particulate Radiation that has an * Average kinetic energy = 4-7 MeV * ionizes approximately 40,000 atoms for every centimeter of travel through the air * Energy is lost quickly because of the amount of ionization. * Travels 5 cm in air; 100 um in soft tissue.

Alpha Radiation

Type of Particulate Radiation that is * Safe if intercepted outside of the body (intercepted by layers of the skin); Intense when intercepted inside the body (Inhaled Radon gas irradiate the lungs).

Alpha Radiation

Type of Particulate radiation that * Differ in terms of mass and charge. * Carry a negative charge but differ from electrons by its origin (nucleus). * Range is longer; 10-100 cm in air and 1-2 cm in soft tissue.

Beta Radiation

Basic Type of Radiation that is * A type of radiation that has both non-ionizing and ionizing capabilities. * Exists over a wide energy range called a an energy continuum. * Has no mass, but has electrical and magnetic energy changing in a sinusoidal fashion. * Travels in the form of photons, which is its smallest quantity.

Electromagnetic Radiation

* Its properties include: Frequency, Wavelength, Velocity, and Amplitude. * Travel at the SPEED OF LIGHT * 3 x 10^8 m/s or 300,000 km/s or……..186,000 miles/s

Electromagnetic Radiation

was coined by James Clerk Maxwell who showed that visible light has both electric and magnetic properties
