Term
| There are three kinds of ionizing radiation: |
|
Definition
alpha particles,
beta particles, and
gamma radiation and x-rays. |
|
|
Term
| ---- particles are heavy; they travel just a few centimeters in the air and are easily absorbed by thin layers of light materials, such as a sheet of paper. They cannot penetrate the skin, so they generally pose the least threat to safety when external |
|
Definition
|
|
Term
| particles are a serious health threat if ingested, inhaled, or absorbed through open wounds. Once within the body, alpha particles are much more cytotoxic and induce more biological damage over a shorter range than do other types of radiation |
|
Definition
|
|
Term
| particles are moderately penetrating, so precautions are necessary when they are handled. The ability of a beta particle to penetrate matter is a function of its energy |
|
Definition
|
|
Term
| particles also produce a secondary form of radiation called bremsstrahlung (also known as “braking radiation”), a type of x-ray produced when these particles are decelerated as they pass through matter. Sheets of Lucite® (a type of plastic) often serve as the primary shield to protect the body from the radiation emitted |
|
Definition

Term
| ---are types of electromagnetic radiation similar to visible light, radio waves, and ultraviolet light, but with higher energy. |
|
Definition
| Gamma (γ) radiation and x-rays |
|
|
Term
| accelerates and collides electrons against a metal target |
|
Definition
|
|
Term
| is generated from radioactive decay |
|
Definition
|
|
Term
| can penetrate through the body, so they represent a serious exposure hazard whether their source is external or internal (ingested, inhaled, or absorbed) |
|
Definition
| Gamma radiation and x-rays |
