What is natural and artificial radioactivity in chemistry?
The elements with atomic number 82-92 are found to radiate spontaneously in nature so they are known as natural radioactive elements.
Whereas the elements that are produced in the laboratory by the bombardment of particles are called artificial radioactive elements.
What is the natural radioactivity?
Natural radiation comprises cosmic radiation and the radiation arising from the decay of naturally occurring radionuclides.
The natural radionuclides include the primordial radioactive elements in the earth's crust, their radioactive decay products, and radionuclides produced by cosmic-radiation interactions.
