of people believe that television is harmless. However‚ scientific studies prove that unlike any other household equipment television sends out a lot of radioactive rays. Indeed‚ radiation deteriorates vision. As well‚ it can damage it. For example‚ some people like to sit close to TV sets. Their eyes are too close to the screen and radioactive rays are constantly getting in their eyes. For that reason‚ television harms people’s vision. Television sends out radiation that has negative effect on people

1. Why are nuclear wastes at times said to be a problem which is too complicated to solve? Radioactive wastes are wastes that contain radioactive material. Radioactive wastes are usually by-products of nuclear power generation and other applications of nuclear fission or nuclear technology‚ such as research and medicine. Radioactive waste is hazardous to most forms of life and the environment‚ and is regulated by government agencies in order to protect human health and the environment. Radioactivity

ABSTRACT Radioactive radiation level was detected for five samples of vegetable leaves namely: Water leaf‚ Fluted Pumpkin‚ Editan Lasientera africana and Afang Gnetum africanum. These vegetable leaves were collected from Uyo (interland region) and Ibeno (coastal region) in Akwa Ibom. Radioactivity level in each of these samples were measured and recorded. In Uyo waterleaf has the least radioactive level of 0.00079Bq/g while Editan has the highest level

ENVIRONMENTAL POLLUTION Efforts to improve the standard of living for humans--through the control of nature and the development of new products--have also resulted in the pollution‚ or contamination‚ of the environment. Much of the world’s air‚ water‚ and land is now partially poisoned by chemical wastes. Some places have become uninhabitable. This pollution exposes people all around the globe to new risks from disease. Many species of plants and animals have become endangered or are now extinct

If someone were to ask you what is radium or who discovered radium‚ would you be able to answer correctly? You may say that radium is not vital in today’s society or that you could care less about radium‚ but what if you were informed that fifteen percent of the world’s electricity is produced with the help of radium and nuclear power plants. Would you change your mind about the importance of radium? Not many people know but‚ radium is also frequently used in the medical field specially to run

Many American’s assume that nuclear waste can be more dangerous than natural radioactive substances already present in the Earth currently. However‚ Richard Muller challenges this assumption in his chronicle “Nuclear Waste” by demonstrating the mathematical differences concerning the half-life of numerous radioactive substances. Basically‚ Muller is warning that “the dangers of storing our waste at Yucca Mountain to be small compared of the dangers of not doing so‚ and significantly smaller than
