Human Radiation Exposure
Normal Cosmic and Earth Based Radiation
USA Average = 60 mrem / yr
Natural Radioactivity in human body tissue
40 mrem = 400 mSv (millisieverts)
Air Flight One Way Trip NYC to London
4 mrem = 40 mSv (millisieverts)
Chest X-Ray
10 mrem = 100 mSv (millisieverts)
Radon in your home (varies depending on abatement and location)
200 mrem = 2000 mSv (millisieverts)
Man Made (Medicine, Chemical Exposure, Watches, etc)
60 mrem = 600 mSv (millisieverts)
A baseline of Common Radiation Exposure Levels:
Ionizing Radiation is the most threatening type of radiation because it is capable of producing charged particles (ions) in matter. It can make a solid object radioactive. It is caused by unstable atoms because they have an excess of energy, mass or both.
The greater the level of radiation the more severe the early effects and the more likely to lead to cancer and other late effects.
The Biological Effects of Ionizing Radiation Committee of the National Research Council (USA) estimates an increase of cancer mortality (deaths) of 790 persons per 100,000 people per 10 rem (10,000 mrem) of exposure.
10 rem = 10,000 mrem = 100 mSv (millisieverts)
