What are three of the natural sources that give off radiation?
- Radiation of cosmic origin- Radiation from radioactive elements (and decay products) of the Earth- Internal radiation of organisms
Where does background radiation originate?
Background radiation can come from all sorts of sources, some natural, some man-made.Examples include...cosmic rays from spaceradon gas emitted from the earth's crustelectromagnetic radiation from a number of possible sourcesatomic radiation from nuclear substances.For much more information see Related links below this box.
How are rotating neutron stars able to produce pulses of radiation as seen by an observer on Earth?
Neutron stars are able to produce pulses of radiation because they are rotating, and only a certain place on the neutron star releases the radiation(just like how light comes out of a flashlight). As the neutron star rotates, the point on the neutron star also moves along. When it points toward the Earth, we see the pulse.
What absorbs Earth's radiation?
It depends on the type of radiation.
Which of these protects the Earth from harmful radiation when found in the stratosphere but is a pollutant at lower altitudes?
Carbon protects the earth from radiation.
What is the background radiation?
Background radiation - is the 'natural' radiation of the Earth. There are radioactive ores naturally present in the ground that give off small amounts of radiation. This is detectable by instruments, but is of no consequence to humans or animals.
What is meant by the term background radiation?
Backround radiation is an explosion which occured in space, which consists of radiation comming from all directions in space.
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.

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.

Why do tidal nuclear and geothermal energy do not depend on the sun.?
Tidal energy comes from the energy of Earth's rotation. This is unrelated to the Sun's radiation. Nuclear energy comes from elements that are available on Earth - it doesn't depend on the Sun's radiation either. Geothermal energy comes from these same elements, which gradually decay, keeping Earth's interior hot.

In 1964 Arno Penzia and Robert Wilson discovered that radiation bombards Earth from all directions in space Cosmologists reason that this radiation is cosmic background radiation left over from the?
A theory that states that the universe began with a tremendous explosion.
What does ozone produce?
Ozone does not produce anything. Ozone layer blocks around 97% of the total radiation received by the earth. It acts as a blanket and keeps the atmosphere cool. It is responsible for the survival of life on earth.
Greenhouse effect events in order starting with lights origin?
Incident infrared radiation is blocked. Visible and ultraviolet radiation heat Earth. Earth radiates infrared radiation. Infrared radiation is blocked and heats Earth. Visible and shortwave radiation heat Earth.Earth radiates longwave radiationLongwave radiation is reflected downward Longwave radiation heats Earth
What is the current residual radiation of hiroshima and nagasaki?
Today, the background radiation in Hiroshima and Nagasaki is the same as the average amount of natural radiation present anywhere on Earth. It is not enough to affect human health. http://www.pcf.city.hiroshima.jp/kids/KPSH_E/question_box/question12.html
