In the United States a unit of radiation dose equivalent in humans is called a rem. Humans are usually exposed to about .003 rem per year from natural background radiation. However an exposure level of five rem is usually fatal to an individual.2
             Take for example the incident that occurred on April 26, 1986. One of the four nuclear reactors at Chernobyl, a nuclear power plant in Russia, exploded. Since the sight did not have a containment building like sites in other countries; a cloud of radioactive fallout spread westward. Hazardous radioactive material spread hundreds of miles into Scandinavia and northern Europe. When the explosion occurred, it is estimated that the core of the reactor was burning at temperature about 2,800 degrees Fahrenheit. Due to this accident, more than 30 people died, and more than 135,000 had to be evacuated from the nearby area.2 This incident provided a wa
