- I'm sorry you had to post megabytes of shit, Dave, without telling anyone
- the MAGNITUDE of dose from weapons fallout and the nuclear power cycle.
- Telling me that my kids are going to be retarded and have one leg longer
- than the other won't hack it.

- Average annual individual doses in mrems from natural and man-made
- radiation sources:
-
- Source Exposed Group Body Portion Exposed Indiv. Dose
- ------------------------------------------------------------------------------
- Natural Radiation:
- External sources:
- Cosmic Rays Total population whole body 28
- Terrestial gammas Total population whole body 26
- Radon and daughters Total population bronchial epithelium ~150
- Internal sources:
- K-40 Total population gonads 19
- bone marrow 15
- Heavy elements Total population gonads 8
- bone marrow 8.5
- C-14 Total population gonads 0.7
- bone marrow 0.7
- Rb-87 Total population gonads 0.3
- bone marrow 0.6
-
- Man-made Radiation:
- Medical x-rays Adult patients bone marrow 103
- Medical personnel whole body 300-350
- Dental x-rays Adult patients bone marrow 3
- Dental personnel whole body 50-125
- Radiopharmaceuticals Patients bone marrow 300
- Medical personnel whole body 260-350
- Weapons fallout Total population whole body 4
- Nuclear power cycle Population<10 miles whole body 1
- Workers whole body 200-400
- Building materials Brick,masonry dwellers whole body 7
- Air Travel Passengers whole body 3
- Crew whole body 160
- Television Viewers gonads 0.2-1.5
- Tobacco Smokers (1.5 packs/d) bronchial epithelium 8000

- Taken from: National Academy of Sciences, "The Effects on Populations of
- Exposure to Low Levels of Ionizing Radiation"; IAEA, "Nuclear Power, The
- Environment, and Man"; National Council on Radiation Protection and
- Measurements, "Natural Background Radiation in the United States"; U.S. EPA,
- "Radiological Quality of the Environment of the United States"
-
- These numbers are several years old, and the doses to radiation and medical
- workers may have dropped from these levels.
