For most of us, the term "radiation," especially when used in the
context of the dirty-bomb threat, implies something sinister,
frightening, and possibly deadly. And with good reason—there
are radioactive sources, both here on Earth and raining down from
space, both natural (like radon) and human-made (like radiological
bombs), that can injure or even kill you.
Yet it may come as a surprise that without radiation you wouldn't be
here. You wouldn't be able to see, feel the warmth of the sun, or
even have food to eat, for virtually all forms of life depend for
their very existence on electromagnetic radiation coming from the
sun.
Sources of Radiation lets you explore an environment to learn about
various types of radiation, both beneficial and potentially lethal.
It is not meant to serve as a comprehensive list of radiation
sources or as a guide to assess potential dangers. For information
about the hazards of radiation and more complete lists of
radioactive sources, check out the Web sites listed in
Links & Books.
