Does most of the radiation exposure for an average citizen in the US come from nuclear power plant operation and early atmospheric nuclear weapons tests?

No, radiation from these sources is negligible. Most comes from natural background, which depends a lot on the geology of the area. Radon is usually the biggest factor (see the link below)

How much radiation is an average person in the USA exposed to each year?
According to NCRP Report #93, "Ionizing Radiation Exposure of the Population of the United States" (1987) the average exposure is about 295 mRem of Natural Background Radiation and about 63 mRem from Manmade Radiation (medical + consumer products) . Most (about 67%) of the natural background radiation is from inhaling Radon gas.
What is the average annual whole-body radiation exposure for a person living in the US?
Around 105.
What is the average exposure of people living in the US to environmental background radiation?
The average worldwide exposure of people to environmental background radiation is about 2.4 mSv (milliSievert) per year. The referenced source does not break that down by country.Ref: "Report of the United Nations Scientific Committee on the Effects of Atomic Radiation to the General Assembly", http://www.unscear.org/docs/reports/gareport.pdf
What is the average annual dose of radiation exposure to radiation workers?
There is no average dose as exposure varies from place to place, but anyone working with radiation should consult their Local Rules for guidance, and wear a dosimeter. The IAEA recommended that the annual dose for workers be under 20mSv. (20 milli-sieverts, where 1 sievert (J/kg) is the radiation required to impart 1 joule of energy in 1 kg of matter.) The UK and the EU have very strict guidelines for staff that work with ionising radiation. These are the dose limits that have been set up to help protect staff from unheathy amounts of radiation. Whole Body Dose Limits Per Year: Radiation Workers ages 18 yrs and older = 50 mSv. Trainees aged 18 yrs and older = 1 mSv General public (frequent exposure) = 1 mSv General public (infrequent exposure) = 5 mSv == == == == == ==
Is there any way to change the average amount of radiation emitted from a radioactive substance?
No, there is none at all. Shielding can be placed around it to limit exposure, but it has no effect on what the substance is emitting.
The average atmospheric pressure?
37463.
What regulates the Earth's average temperature?
atmospheric pressure
Is radiation a measure of the average kineic energy of the particles in an object?
No, radiation is not a measure of the average kinetic energy of particles in an object. Radiation refers to the emission of energy as electromagnetic waves or particles from a source. The energy of radiation can vary depending on the type and source, and it is not directly related to the average kinetic energy of particles in an object.
What is the name of the condition when the average velocity of atmospheric molecules around you is not zero?
Wind
What evidence indicates that the rising atmospheric carbon dioxide levels are caused by the combustion of fossil fuels?
the average global temp and the atmospheric co2 level has risen
Why is it cold at the poles?
The answer to this question involves the angle at which solar radiation is intercepted by the earth's atmosphere. The rule is that if solar radiation is incident perpendicular to the atmosphere the solar radiation that is incident on the earth's surface will be greatest. Incoming solar radiation at the poles comes in at a sharper angle and is spread over a greater surface area of atmosphere than at the equator. In this way, the poles have more of an atmospheric filter and experience less radiation per area time and hence have lower average temperatures.
Can too much radiation from x-rays and ct-scan cause infertility in men?
Yes but the level of exposure that the average person would have to receive in order for that to occur is typically more than the typical diagnostic exposure time a patient would receive on a single visit. While CT's to give the most exposure at one time, unless it was a direct shot to the testes, one CT is unlikely (thought not impossible. There are rare exceptions to all cases with radiation) that it would happen. X-rays are far lower dosage and shielding of a patient's reproductive organs is typically done by technologists at all possible times.
