Rocks and soil contain small amounts of naturally occurring radioisotopes as well as various amounts of fallout from atmospheric nuclear testing and the Chernobyl reactor accident. Cosmic rays are in large part nuclei ejected with high velocity by ancient supernovas.

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!
Why do white rocks avoid water evaporation?
White rocks reflect the thermal radiation from the Sun.
Can radiation preserve mummies?
Radiation can kill fungi and decay bacteria, so yes.
What kinds of rocks are caused of weathering?
Metamorphic rocks change into sediments through weathering
What is a weathing rocks?
give support this main idea: weathering of rocks is caused by several forces.
Is there any radiation on mars?
Yes: sun light, solar wind, cosmic rays, weak background from rocks and soil.
What is background radiation List some of its sources?
Background radiation is the nuclear radiation that arises naturally from cosmic rays and form radioactive isotopes in the soil and air. Some of its sources are : the sun, heat, soil, rocks, and plants.
What are the five sources of background radiation?
earths crust, radon gas, cosmic rays, natural sources e.g food, water and rocks.

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.
Do certain areas of the country have higher levels of background radiation than others?
Yes, certain areas of the country can have higher levels of background radiation than others. This can be due to the geological makeup of the region, with areas containing more naturally occurring radioactive materials. Additionally, human activities such as mining, industrial operations, and nuclear facilities can contribute to higher background radiation levels in certain areas. However, it is important to note that these variations in background radiation levels are generally within safe limits and have minimal impact on human health.
What are comets and meteors?
Comets are body of ice, rocks and cosmic dust loosely packed together.Meteor is a streak of light caused when comets dust and meteoride burns up in the earth atmosphere before it reaches the ground.
What rocks are caused by weathering?
Sedimentary rocks.
Which kinds rocks are caused by weathering?
sedimentary rocks
Why do white rocks avoid water evaporation?
White rocks reflect the thermal radiation from the Sun.
Can radiation preserve mummies?
Radiation can kill fungi and decay bacteria, so yes.
Why are earthquakes caused by rocks breaking?
Vibrating through movement of rocks
