Radioactive elements are those elements that produce radiation. Radioactivity is the phenomenon of uncontrolled radiation releases through radioactive substances. Three-fourths of the surface of the planet is made up of oceans. It would have been inconceivable to conceive that people could severely damage these enormous quantities of water less than a century ago. Humans have been using the ocean as a landfill for trash and other waste for as long as there have been people living near the shore. Radiation is a characteristic of the natural world. It's critical to consider the overall radiation exposure, both internal and external, arising from both natural and artificial sources when evaluating how radiation affects people. Cosmic rays from extraterrestrial sources and terrestrial radiation sources both contribute to external exposure. This study focuses on the effects of radioactive waste on our environment. The results conclude that more than almost any other environmental occurrence, radioactivity in the environment prompts a strong response from the people.
