Radiation, Nonionizing Categories.
 |
High-Energy Shock Waves - Compression waves of large amplitude, across which density, pressure, and particle velocity change drastically. (From McGraw Hill Dictionary of Scientific and Technical Terms, 5th ed) |
|
Microwaves - That portion of the electromagnetic spectrum lying between UHF (ultrahigh frequency) radio waves and heat (infrared) waves. Microwaves are used to generate heat, especially in some types of diathermy. They may cause heat damage to tissues. |
|
Radio Waves - That portion of the electromagnetic spectrum beyond the microwaves, with wavelengths as high as 30 KM. They are used in communications, including television. Short Wave or HF (high frequency), UHF (ultrahigh frequency) and VHF (very high frequency) waves are used in citizen's band communication. |
