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.
