People receive some natural or background radiation exposure each day from?

There are several sources of natural or background radiation for people.
First, there are naturally occurring radioactive elements in the crust of the earth which have been present since the earth's formation. These can irradiate people in several ways.
- They can irradiate people externally because the soil and rocks all around us (and some building materials such as concrete and brick) act as radiation sources.
- Plants and animals that we use for food take in the radioactive elements and we ingest them along with our food.
- Some of the radioactivity is present in the air and we inhale it along with the air.
Second, there are radioactive elements which are produced by interactions of cosmic rays with the atmosphere, the best known being carbon-14 and hydrogen-3 (or tritium). These can irradiate us in much the same ways as the elements discussed above.
Third, we are constantly irradiated by cosmic rays.

Does a TV screen emit light?
It depends upon the position of the tv.If its on its a luminious object as it generates its own light and when its switched off its a non- luminious object as it has stopped generating light
Does solar power generation work in the woods?
As long as you have an open area where a solar panel would receive plenty of sunshine you can set it up anywhere. You may want to hire a professional to advise you where to place it for maximum exposure and soaking up the sun's rays.
What role do alleles play in natural selection?
Genes are the medium by which inherited traits are passed on to offspring. It is inherited traits, and thus genes, that receive positive or negative selection.
A synthetic element that is used in smoke detectors is?
Americium-241 this is an emitter of alpha radiation, which is used in smoke detectors as it is very ionising and will not be able to travel through smoke. Therefore, in a fire the detector will not receive any alpha radiation and hence the alarm will go off.
Not all areas on Earth's surface receive the same amount of radiation because Earth's surface?
Mainly the degree of radiation from the Sun which strikes the Earth's surface is due to parts of the Earth offering its surface at different angles to the Sun at different stages of the Earth's 365 rotation about the Sun, and the Earth's own rotation with its axis being tilted with respect to the Sun.
From which direction do you receive background radiation from the big bang?
From every direction that isn't blocked by the earth. The amplitude of the background radiation is almost exactly constant from all directions.
How do you prevent exposure to radiation?
Seal yourself in a lead box with no doors or windows. Actually, even that is insufficient, since you'll still receive thermal radiation. It's ridiculous to talk about "preventing" exposure to radiation, since light is radiation, as is heat, and you can't completely prevent exposure even to more harmful forms like cosmic rays.
How much radiation do you receive per year in your lives?
.2 gamma radiation every year for humans but it is natural
Why is it not safe for the technician to be in the room when the x-ray is taken?
X ray technicians are around the radiation of x-rays all day every day. They need to keep their exposure down to minimum and have to wear badges that monitor how much radiation they receive on a monthly to yearly basis. There is a limit to the amount of radiation exposure a tech can receive without harmful effects to their body or health. Whereas patient's don't typically get x-rays or radiation exposure on the regular basis so a couple x rays aren't likely to cause any adverse effects.
What are some primary contributors to background radiation?
Radiation is a natural part of the universe. It comes from cosmic rays, the big bang, stars, rocks, soil, and gasses. Even BANANAS are radioactive. Google "radioactive bananas" for a real treat!
How much radiation would a passenger receive in a 7 hour airplane flight?
Radiation? You don't get radiation flying!
What is risk of radiation in California by Japan crisis?
Currently, you are far more likely to be hit by lightening twice than to have any issue with the radiation from Japan in any portion of the United States. The background radiation numbers in Tokyo (only 150 miles away from the problem) are roughly the same as we have normally in New York. You will receive more radiation from a window seat in a plane, then you will from this situation.
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.
What are some naturally occurring ways we receive radiation?
I assume you mean ionizing electromagnetic radiation. Cathode ray tube televisions (i.e. the non-flatscreen televisions) and some other electric devices produce some radiation. While it might sound pretty excessive all these sources add up to a very small amount of radiation. About 2.4 mSv. Most additional radiation people receive are from medical imaging methods such as a CT-scan (20 mSv)
What is the penalty for indecent exposure in the state of Missouri?
A person may receive a fine of up to $20,000. A person could also receive up to a year in prison for indecent exposure.
Are tanning beds generally safe?
You are exposed to ultraviolet radiation inside a tanning bed, just as you are in the sun. This UV exposure causes skin cancer, regardless of the source. In addition, you can receive a bad burn in a tanning bed just as you can in the sun. So tanning beds are generally no safer than sun exposure.
How much of the energy that reaches earth is supplied by the sun through the radiation?
