2 types of radiation
Non-ionizing radiation,
Ionizing radiation
Capable of removing an electron from an atom
Ionizing Radiation
2 Sources of Ionizing Radiation
Natural Environmental Radiation,
Man-made Radiation
annual dose of Natural Environmental Radiation
approximately 300 millirem (mrem) (3 millisievert [mSv])
Examples of Natural Environmental Radiation
Cosmic rays, terrestrial radiation, internally deposited radionuclides
Annual dose of Man-made Radiation
Approximately 3.2 mSv
Examples of Man-made Radiation
Medical imaging, nuclear power generation, research application, industrial sources, consumer items
Diagnostic x-rays
Man-made Radiation
Two Types of Ionizing Radiation
Particulate radiation,
Electromagnetic radiation
is the radiation of energy by means of fast-moving subatomic particles
Particle radiation
2 Particulate Radiation
Alpha Particles,
Beta Particles
are high energy, large subatomic structures of protons and neutrons
Alpha particles
