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)
Some naturally occurring ways we receive radiation include cosmic radiation from outer space, radon gas from the ground, and radiation from radioactive materials in rocks and soil. Additionally, radiation is also present in foods and our own bodies.

Are all the elements naturally occurring manmade or both?
Not all the elements occur naturally; some elements are man-made.
Is zircon manmade?
Zircon itself is a naturally occurring mineral, so it is not manmade. However, some zircon gemstones undergo treatments, such as heat treatment, to enhance their color or clarity, but the base mineral itself is natural.
Can a natural isotope be radioactive?
Yes, a natural isotope can be radioactive. Some natural isotopes have unstable nuclei and undergo radioactive decay to achieve a more stable form. This process involves the emission of radiation in the form of alpha particles, beta particles, or gamma rays.
Which elements found in nature have mainly radioactive isotopes?
Some elements found in nature that mainly have radioactive isotopes include uranium, thorium, and potassium. These elements have naturally occurring radioactive isotopes that decay over time, releasing energy in the form of radiation.
Why do we say that some elements aren't naturally occurring?
Some elements are not naturally occurring because they are created in laboratories through nuclear reactions or particle accelerators. These synthetic elements do not have stable isotopes and decay rapidly, making them difficult to find in nature. Examples include elements beyond uranium on the periodic table.
Why does light have to be invented?
Light doesn't have to be invented. Emitting radiation in the form of light is a naturally occurring phenomena under some conditions.
Are all the elements naturally occurring manmade or both?
Not all the elements occur naturally; some elements are man-made.
What are some naturally occurring hazards in Mexico?
Cenotes
CFC's are A Naturally Occurring B Man-Made C Produced by Bacteria D None of the Above?
CFC's are naturally occurring. Some people disagree and say they are completely man made.
What is background radiation List some of its sources?
Background radiation is the ionizing radiation present in the environment from natural and human-made sources. Some sources include cosmic radiation from space, radioactive elements in the Earth's crust, and medical procedures like X-rays. It is constantly present and contributes to the overall radiation exposure that individuals receive.
Do lions live in Germany?
Lions are not naturally occurring in Germany, but some live in zoos and parks.
Most of the naturally occurring elements are?
Most of the naturally occurring elements are metals. These elements are found in the Earth's crust and have various physical and chemical properties. Some examples of naturally occurring metals include iron, copper, and gold.
Why is there naturally occurring technetium on earth?
Natural technetium exist only in infinitesimal traces in some uranium deposits.
What are some natural phenomons?
Natural disasters such as tornadoes, hurricanes, and thunderstorms, or naturally occurring phenomenae such as the Northern Lights.
Is zircon manmade?
Zircon itself is a naturally occurring mineral, so it is not manmade. However, some zircon gemstones undergo treatments, such as heat treatment, to enhance their color or clarity, but the base mineral itself is natural.
Can a natural isotope be radioactive?
Yes, a natural isotope can be radioactive. Some natural isotopes have unstable nuclei and undergo radioactive decay to achieve a more stable form. This process involves the emission of radiation in the form of alpha particles, beta particles, or gamma rays.
Why are rust spots appearing on the cement walkway?
I have seen this happen when there is some naturally occurring iron in the stone used in the mix.
