Types of Radiation Non-Ionizing radiation is low energy and does not change atoms. Examples: Light, Radio Waves, Microwaves.

Types of Radiation Ionizing radiation has high energy and can remove electrons from other atoms. Examples: X-Rays and Gamma Rays

Nuclear Physics The nucleus of an atom is held together by the strong force. [

Nuclear Physics When the strong force fails, p + or n can escape, and the atom is radioactive. [

Radiation & Health The amount of radiation a person receives in a year can be measured in rems. (Roentgen Equivalent Man) 1 rem = 1000 mrem (millirem)

Radiation & Health Stochastic (long term) exposure to radiation can include health effects such as DNA mutation & Cancer Average US citizen receives 360 mrem per year. (0.36 rem) EPA guidelines allow for 5000 mrem per year if working around radiation as a job. (5 rem)

Radiation & Health Non-Stochastic (short term) exposure can include health effects that lead to massive cell death and “radiation sickness” [ Click here for EPA descriptions of health limits
