Why does a Geiger counter occasionally click even if no artificial radioisotopes are nearby?
A Geiger counter can sometimes click due to natural background radiation from sources such as cosmic rays, radon gas, and radioactive isotopes in the earth. These sources can produce random bursts of radiation that the Geiger counter detects as clicks.
What are some of the sources of beta radiation?
Some common sources of beta radiation include radioactive isotopes such as strontium-90, tritium, and carbon-14, as well as certain nuclear reactors and particle accelerators. Beta radiation is also emitted during the decay of some fission products in nuclear power plants.
What are the things that have radiation?
Some common sources of radiation include sunlight, medical imaging tests like X-rays and CT scans, radioactive materials used in industry and research, and natural sources like radon gas and cosmic radiation.
Where is background radiation highest in the UK?
Background radiation levels in the UK can vary, but typically, it is higher in areas with higher concentrations of certain elements like uranium and radon. Some areas in the southwest of England, such as Cornwall and Devon, have higher levels of background radiation due to the presence of granite rock which contains higher levels of radioactive elements.
What contributes to background-radiation exposure?
Many things. Some of which are Radon gas, trace radioactive materials in food and water, high energy gamma rays from space, nuclear weapon fallout, coal ash, luminus watch dials, and pottery fired with uranium based glazes.

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.
If you could block all radiation from sources outside your body explain why you would still be exposed to some radiation?
Some of the elements in your body are naturally radioactive. e.g. potassium, some carbon, etc. You get a larger exposure to radiation from the decay of potassium in your body, than you will from a smoke detector based upon radioactive americium.
What is the concept of radioactivity that's always there?
This is probably a reference to what is called background radiation. Background radiation has a number of contibuting factors, but it is "always there" in some form or another owing to radioactive decay of radioisotopes and to cosmic radiation and its effects.
What are some of the sources of beta radiation?
Some common sources of beta radiation include radioactive isotopes such as strontium-90, tritium, and carbon-14, as well as certain nuclear reactors and particle accelerators. Beta radiation is also emitted during the decay of some fission products in nuclear power plants.
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!
What are some sources of ultraviolet radiation?
The sun, stars, uv lights, and tanning beds.
What are the things that have radiation?
Some common sources of radiation include sunlight, medical imaging tests like X-rays and CT scans, radioactive materials used in industry and research, and natural sources like radon gas and cosmic radiation.
What is low levels of radiation?
Low levels of radiation refer to exposure that is typically considered safe and does not pose significant health risks to humans. This can include natural background radiation from sources like cosmic rays and radon, as well as man-made sources like medical imaging and certain industrial applications. Regulatory agencies often define thresholds for low radiation exposure, which are measured in units such as millisieverts (mSv). Chronic exposure to low levels of radiation may carry some risk, but it is generally viewed as minimal compared to higher levels of exposure.
Where is background radiation highest in the UK?
Background radiation levels in the UK can vary, but typically, it is higher in areas with higher concentrations of certain elements like uranium and radon. Some areas in the southwest of England, such as Cornwall and Devon, have higher levels of background radiation due to the presence of granite rock which contains higher levels of radioactive elements.

What is the difference between cosmic background radiation and red shift?
Cosmic microwave background radiation is a specific radiation. Red shift is a change in frequency due to the fact that an object moves away from us (or for some other reason, such as a gravitational well); and that affects ALL types of radiations.
