What is an X-ray Grid Sciencing

 · Purpose. An X-ray grid is a filtering device that ensures the clarity of the image on X-ray film. When an X-ray machine sends radiation through an object specifically a body the object absorbs or deflects most of the rays. Only about 1 percent of the X-rays pass through the body on a straight line and burn an image onto the film.
