What’s Radioactivity? What’s are the most RADIOACTIVE places on Earth?

We experience little amount of Ionizing radiation all the time. Even, in banana some of the potassium is Radioactive. So, we are exposed to very little amount of radioactivity that is 0.1 micro sieverts of radiation. Hey don’t worry that does no harm, anything greater than 2 sieverts at once probably kills, in a short time . Ok let’s go further learning, what radioactivity actually is?

In radioactive electromagnetic radiation are emitted from the nucleus. The most common forms of radiation emitted are alpha (a), beta (b), and gamma (g) radiation. Nuclear radiation occurs in other forms, including the emission of protons or neutrons or spontaneous fission of a massive nucleus.

An unstable nucleus will decompose spontaneously, or decay, into a more stable configuration but will do so only in a few specific ways by emitting certain particles¬†or certain forms of electromagnetic energy. Radioactive¬†decay is a property of several naturally occurring elements as well as of artificially produced isotopes of the elements. The Radioactivity is measured in “SIEVERTS”.

The above video shows the most radioactive places on earth. So, a smokers lungs receives the highest radiation, that is 160,000 microsieverts per year.
