That is not currently known for sure. Check the Wikipedia article on "Ultra-high energy cosmic rays" for different explanations about how they MIGHT be caused.

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.


Does cosmic background radiation comes equally from all directions?

Yes. Its isotropic nature is to one part in ten thousand. This is easy to explain with Big Bang Cosmology, impossible to explain without it. Its minor non-isotropies match exactly what would expect if our Universe began in an inflationary manner.


What percentage of human exposure comes from outer space rocks soil radon gas and the human body?

About 80% of human exposure to radiation comes from natural sources, including outer space (cosmic rays), soil (terrestrial radiation), and radon gas. Cosmic rays contribute approximately 8% of this exposure, while radon gas accounts for about 55%. The remaining exposure comes from terrestrial sources and the natural radioactivity present in the human body itself. Overall, these natural sources contribute significantly to the background radiation that humans are exposed to.


Where does background ultraviolet radiation come from?

it comes from space circle jerk


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!

Where does most background radiation come from?

Most background radiation comes from natural sources, primarily cosmic rays from outer space and terrestrial radiation from radioactive materials in the Earth's crust, such as uranium, thorium, and radon. Additionally, some background radiation is contributed by human-made sources, including medical procedures, nuclear power plants, and fallout from nuclear weapons testing. Overall, natural sources account for the majority of the background radiation that people are exposed to daily.


Electromagnetic radiation that comes from the outer space is?

Cosmic radiation consists of high-energy particles and electromagnetic radiation, including gamma rays, X-rays, and ultraviolet radiation, that originate from sources in outer space such as the Sun and other celestial bodies.


What is the source that the average person receives the largest dose of radiation?

The largest dose of radiation that the average person receives is from natural background radiation, which comes from cosmic rays, radon gas, and radioactive materials in the Earth's crust. This exposure is generally higher than radiation received from medical procedures or nuclear power plants.

What is the largest source of radiation on earth?

The largest source of radiation on Earth is natural background radiation, which primarily comes from cosmic rays, terrestrial sources, and radon gas. Cosmic rays originate from outer space and interact with the Earth's atmosphere, while terrestrial radiation is emitted from radioactive materials in the Earth's crust, such as uranium, thorium, and potassium-40. Radon, a radioactive gas that seeps from the ground, contributes significantly to the overall exposure to natural radiation. Together, these sources account for the majority of the radiation humans are exposed to in their daily lives.

What Annual exposure from radiation non smoker?

The annual exposure to radiation for a non-smoker primarily comes from natural background radiation, which averages about 2-3 millisieverts (mSv) per year globally. This radiation originates from cosmic rays, terrestrial sources, and radon gas, among others. Additionally, non-smokers may have slightly lower exposure to radiation from certain sources associated with smoking, such as radon in homes. Overall, the health risks from this background radiation are considered minimal for the general population.
