Too Much Radiation Can Cause Us Harm
Obviously, we are exposed to many sources of radiation in
everyday life and no matter what we do, we cannot avoid them.
The radiation that we receive from the earth is very minimal and
has been around since the beginning of time (and it will always
be around). However, some of our own activities has in fact
increased the amount of radiation we are exposed to during our
everyday lives.
The detonation of nuclear weapons releases massive amounts of
radiation. The debris from a nuclear blast is radioactive and
eventually settles to the earth. Nuclear reactors also generate
radioactive materials, but the radiation created from reactors
is in most cases contained.
X-rays used in medical and dental procedures are definitely
contributors to man-made radiation. We all need x-rays from time
to time, but it is best not to overdue it. This is why medical
professionals leave the room when they x-ray a patient. Nuclear
medicine, which may even be used to treat cancer, is another
factor adding to the radiation doses people recieve. The use of
radioactive materials in research settings can also be a hazard.
It is advised that anyone exposed to radiation in their daily
work environment take the proper precautions.
Many products for sale to consumers are radioactive. Some of
these include T.V.'s, luminous-dial watches, smoke detectors,
tobacco products and building materials. In addition, cellphones
are a possible cause of radiation. At this time, it is currently
unknown how much radiation these sources add to our exposure.
