⇐ ПредыдущаяСтр 2 из 2


RADIATION

  Radiation is an invisible pollutant that can be highly dangerous. Nuclear radiation comes from radioactive substances, including waste from nuclear weapons testing and from nucle­ar power plants. Small amounts of electromagnetic radiation are produced by a variety of electronic devices including comput­ers, lasers, microwave ovens, TV sets, and X-ray machines.

  Scientists have not determined exactly what effects small amounts of radiation influence people. But exposure to large amounts can cause cancer and harmful changes in reproductive cells.

International agreements ban most testing of nuclear weapons in the atmosphere. Such regulations have helped to elimi­nate the major sources of radiation. However, the amount of radioactive waste is constantly increasing. Scientists are study­ing the ways to eliminate these wastes safely and permanently.
