Radiation Exposure
People with A-T have an increased sensitivity to ionizing radiation (X-rays and gamma rays). Therefore, X-ray exposure should be limited to times when it is medically necessary, as exposing an A-T patient to ionizing radiation can damage cells in such a way that the body cannot repair them. The cells can cope normally with other forms of radiation, such as ultraviolet light, so there is no need for special precautions from sunlight exposure.

Famous quotes containing the word radiation:
“There are no accidents, only nature throwing her weight around. Even the bomb merely releases energy that nature has put there. Nuclear war would be just a spark in the grandeur of space. Nor can radiation “alter” nature: she will absorb it all. After the bomb, nature will pick up the cards we have spilled, shuffle them, and begin her game again.”
—Camille Paglia (b. 1947)
