Facts About Radiation

Interesting facts about radiation will help you learn about its many different manifestations in nature. Many people associate radiation with something frightening and deadly, but in some cases, it can be beneficial.

For example, small amounts of radiation can be used to treat various diseases, including cancer.

So, here are the most interesting facts about radiation:

Fact 1: There is more radiation in nature than most people realize. Both minerals and plants are radioactive. For example, all of the granite mined in the world is slightly radioactive, though in safe doses, with few exceptions. And bananas are the most radioactive fruit in the world. But it would not take a lifetime to get radiation sickness from eating bananas, even if you don’t eat any other food.

Fact 2: Human activity is slowly but surely increasing the radiation background on the surface of the entire planet. This process is relatively safe because the changes are very slow, but even now, thanks to good isolation, radiation levels aboard nuclear subs are lower than on the surface.

Fact 3: It’s not the employees of nuclear power plants who receive the most radiation, but the crews of commercial airplanes. It is the atmosphere that protects us from radiation and pilots and stewardesses spend a good deal of their lives in the upper layers of the atmosphere.

Fact 4: The whole world is now aware of the dangers of radioactive contamination. But in the last century not even scientists believed in it and after the U.S. aerial bombing of Hiroshima and Nagasaki, the inhabitants soon returned to these cities. And after the disaster at Chernobyl, some residents refused to leave, and stayed in their homes. Some of them still live there.

Fact 5: The level of protection from radiation at modern nuclear power plants is very high. Primitive thermal power plants, which consume hard coal and process it into electricity, are much more radioactive than nuclear power plants. But for some reason there are supporters of shutting down nuclear power plants, and there are quite a few of them, while there are not supporters of shutting down thermal power plants.

Fact 6: Purely theoretically, radiation coming from the depths of space can destroy all life on Earth. It could happen if a star somewhere nearby goes supernova and our planet gets hit by a narrow beam of gamma rays. Although in 2004, scientists recorded the most powerful burst of cosmic radiation in the history of observations, reaching our planet from a neutron star many light years away.

Fact 7: There is more radiation in space than on Earth. More precisely, the cosmic space is simply permeated with it. It is called relict radiation, and scientists believe it is left over from the Big Bang about 14,000,000,000 years ago.

Fact 8: Radiation was not considered dangerous for a long time. For example, the radioactive element radium was added to drinks and toothpaste in the 20th century and Young Chemist kits for children were sold in the United States that included radioactive minerals.

Fact 9. American lunar expeditions left U.S. flags on the Moon. They are still there, but whitened, completely faded. This is a consequence of solar radiation, since there is no atmosphere on the Moon.

Fact 10: It is the last fact about radiation. The bodies of city dwellers are more radioactive than those of rural dwellers, and the average metropolitan dweller is more radioactive these days than his smartphone. A couple of hundred years ago, people’s bodies weren’t radioactive, but the further we go, the more radiation appears in the world around us, and in our bodies, too. The bodies of the people of the future will be even more radioactive than ours.
