3. Outline Ionizing vs. Nonionizing Radiation Biological Effects
Typical Nonionizing Systems in DOD
Control Measures

4. Ionizing vs Nonionizing Radiation
Higher energy electromagnetic waves (gamma) or heavy particles (beta and alpha).
High enough energy to pull electron from orbit.
Nonionizing Radiation
Lower energy electromagnetic waves.
Not enough energy to pull electron from orbit, but can excite the electron.

5. Examples on Nonionizing Radiation Sources
MICROWAVE
GAMMA
ULTRA V
VISIBLE
INFRARED TV AM RF
