"Uranium is the most efficient power plant fuel. A single uranium fuel pellet, about the size of a pencil eraser, contains as much energy as:
*149 gallons of oil
*157 gallons of gasoline
*1,780 pounds of coal
*17,000 cubic feet of natural gas
Nuclear power is carbon-free and emits no greenhouse gases. It produces 20 percent of America's electricity and almost 75 percent of all emission-free power generation, nationwide."
Nuclear power is the world's largest source of emission-free energy. Nuclear
power plants produce no controlled air pollutants, such as sulfur and
particulates, or greenhouse gases.
As its name implies, radioactivity is the act of emitting radiation
spontaneously. This is done by an atomic nucleus that, for some reason, is
unstable; it "wants" to give up some energy in order to shift to a more stable
configuration.
This gives a great perspective on fossil fuel powered factories. It also gives a great deal of information on how nuclear energy effects the enviornment
Radiation may come from either an external source, such as an x-ray machine,
or an internal source, such as an injected radioisotope. The impact of
radiation on living tissue is complicated by the type of radiation and the
variety of tissues.
Altering chemical bonds may change composition or structure. Ionizing
radiation is powerful enough to do this. For example, a typical ionization
releases six to seven times the energy needed to break the chemical bond
between two carbon atoms.
It takes much longer for the biological effects to become apparent.
If the damage is sufficient to kill the cell, the effect may become noticeable
in hours or days.
