X-RAY: Similar to light, they are energy in the form of waves. Because they have more energy than light waves they are able to pass through the body and take pictures. The unit to measure x-rays is the "rem", this is a very large unit and for practicality it is decreased to the unit called the "millirem" (one thousandth of a rem). A dental x-ray exposes a person to 0.5-3 mrem. It is estimated that on the average people are exposed to 360 mrem a year from sources like radiation in foods. The maximum yearly exposure is considered 5,000 millirems. Small doses that are accumulative are preferable to single large doses because the body has time to recover and repair damage prior to receiving and new small dose.
