Unit 1 Fundamental Concepts 1-5 Radiation Penetration Into Skin Exposure to beta particles from outside the body is normally thought of as a slight hazard. However, if the skin is exposed to large amounts of beta radiation for long periods of time, skin burns similar to heat burns may result. If removed from the skin shortly after exposure, beta-emitting materials will not cause serious burns and will not pose a severe external hazard. Like alpha particles, beta particles are considered to be an internal hazard if taken into the body by eating food, drinking water, or breathing air containing radioactive material. Beta emitting contamination can also enter the body through unprotected open wounds. Gamma Gamma rays are similar to medical x-rays. As discussed earlier, gamma rays are a type of electromagnetic radiation, energy transmitted through space in the form of waves. Physical characteristics of

Unformatted text preview: electromagnetic radiation include wavelength and frequency. Different types of electromagnetic radiation have unique wavelengths and frequency. By measuring these characteristics, the type of radiation can be identified. Short wavelength and high frequency are characteristic of radiations, such as gamma and x-rays. Gamma rays are the most hazardous type of radiation from sources outside the body because they can travel much greater distances through air and all types of material. Gamma rays can travel up to a mile (1.6 km) in open air and may present a significant hazard even at fairly large distances. Since gamma rays penetrate more deeply through the body than alpha or beta particles, all tissues and organs can be damaged by sources outside of the body....
