Radiation is natural and found everywhere – it comes from outer space, the air we breathe, and the earth we tread. It's even in our bodies; naturally occurring radioactive elements in our bones irradiate us on average 5000 times per second.

Where is radiation most commonly found?

The majority of background radiation occurs naturally from minerals and a small fraction comes from man-made elements. Naturally occurring radioactive minerals in the ground, soil, and water produce background radiation. The human body even contains some of these naturally-occurring radioactive minerals.

What are 3 sources of radiation?

Natural background radiation comes from the following three sources:

• Cosmic Radiation.
• Terrestrial Radiation.
• Internal Radiation.

Where is radiation in the earth?

The global average solar radiation arriving at the outer edge of the Earth's atmosphere is 340 watts per square metre. About seven per cent of the incoming radiation is UV radiation, 46 per cent is in the range of visible light, and the remaining 47 per cent is in the infrared spectrum.

Where does the radiation occur?

Most of it forms naturally from minerals. These radioactive minerals are in the ground, soil, water, and even our bodies. Background radiation can also come from outer space and the sun. Other sources are man-made, such as x-rays, radiation therapy to treat cancer, and electrical power lines.

Do phones have radiation?

Yes – cell phones and cordless phones use radiofrequency radiation (RF) to send signals. RF is different from other types of radiation (like x-rays) that we know can be harmful.

How much radiation can a human take?

Adult: 5,000 Millirems. The current federal occupational limit of exposure per year for an adult (the limit for a worker using radiation) is "as low as reasonably achievable; however, not to exceed 5,000 millirems" above the 300+ millirems of natural sources of radiation and any medical radiation.

What is the strongest form of radiation?

Gamma rays Gamma rays are the strongest from of radiation. This is what makes nuclear radiation so dangerous. This high energy form of radiation can damage human tissue and cause mutations.

What does radiation look like in the air?

How is Earth’s radiation?

Atmospheric radiation is the flow of electromagnetic energy between the sun and the Earth's surface as it is influenced by clouds, aerosols, and gases in the Earth's atmosphere. It includes both solar radiation (sunlight) and long-wave (thermal) radiation.
