In the past few decades the medical community has become increasingly adept at, as well as increasingly dependent upon, diagnosis by radiography. However, there exists a growing concern over the possibility that cellular and genetic damage is being done by the large amounts of x-radiation turned upon the populations of medically advanced countriesI . The state of the art has considerably reduced the dosages required to obtain satisfactory radiographic images in an attempt to reduce doses to a safe level. However, radiobiologists have studied the effects of low radiation doses on different cell lines in vivo in the hopes that some threshhold would be found below which permanent damage ceases to occur. Unfortunately there are now grounds for believing that the probability of genetic change follows the dose down to nearly zero.
