These screens are a great deal more sensitive to x-rays than is movie. In the event the x-ray strikes a crystal, it brings about the crystal to phosphoresce, and The sunshine exposes the film secondarily. This method of recording the x-ray image is considerably more efficient than employing movie alone and markedly lessens radiation publicity to the subject (from time to time by a factor of one hundred or maybe more) and also the operator. What's more, it reduces the quantity of scatter radiation recorded over the image. The screens and film are contained in a very lightproof cassette, which is transparent to x-rays.
