Radioactive. Elements. Are naturally. Unstable. Their nuclei. Disintegrate. And emit rays. (Radioactive) that are harmful to living things.
The new stable nuclei are formed examples of radioactive elements are uranium,barium and radium

Geiger counter
Some uses of the. Radioactive. Elements
(A) determine the age of fossils. By analyzing the percentage of carbon -14 (radio active element) in fossils,the ages of the fossils can be determined.
(B) producing energy radioactive elements are used in nuclear fission where huge amount of energy is released under controlled situation. This energy controlled situation this energy can be used to heat materials like water and then do work like generating electricity
(C) medical uses some radioactive. Elements are used in diagnosis to. Generate images of organs and glands and in treatment for condition such as cancer.
