How to Stay Safe Around X-Ray Equipment?

   X-rays penetrate the body and allow doctors to see what's going on inside. They provide a picture of internal structures that help doctors make an accurate diagnosis. There are risks, because of the radiation involved, but the amount of radiation exposure from one chest X-ray is equivalent to the exposure you experience from natural surroundings in 10 days. In most cases, the benefits of an X-ray far outweigh the dangers.
      Instructions
      1.Wear lead body aprons and shields. Both protect patients from radiation, though modern equipment filters out unnecessary X-rays and restricts the X-ray beam to the area of interest.
      2.Leave the room. Anyone who is not covered in a lead apron and shield should leave the X-ray room before the image is taken. Even though the radiation is aimed at the person in the chair, it's still risky to be in the room at all.
      3.Use with care. Radiologists and X-ray technicians (using mobile x ray machine and stationary x ray machine)are trained to use the minimum amount of radiation necessary to obtain the image they need. Radiation is released only when a switch is turned on quickly. Once it's turned off, no radiation remains in the room.
      4.Inform doctor if you may be pregnant. Medical X-rays don't pose a tremendous risk to your baby, but there is a small chance of causing illness or other complication. It depends on how far along you are with the pregnancy.
