CHATPTER 2 Rafiology

Wavelength

The distance between the crest of one wave and the crest of the next.

Electromagnetic

Examples included cosmic rays, gamma rays rays, x-rays, ultraviolet rays, visible light, infrared light radar waves, microwaves, and radio waves

Primary

This type of radiation refers to the penetrating x-ray beam that is produced at the target of the anode and that exits the tubehead

radioactivity

the process by which certain unstable atoms or elements undergo spontaneous disintegration or decay in an effort to attain a more balanced nuclear state

frequency

The number of wavelengths that pass a given point in a certain amount of time

electrons

Tiny, negatively charged particles that have very little mass

Particulate

Type of radiation composed by tiny particles of matter that possess mass and travel in straight lines at high speeds

scatter radiation

This type of radiation is the result of an x-ray that has been deflected from its path by the interaction with matter

orbit

a well-defined path

velocity

This term refers to the speed of the wave

nucleus

The dense core of the atom; composed of protons and neutrons

ionizing

Radiation are capable of producing ions by removing or adding an electron to an atom.
