What is the material of the X-ray film?

X-ray film is coated with silver halide material on polymer PET film. Among them, the photosensitive material silver halide is mainly the photosensitive material silver iodide, or silver bromide and silver chloride, while the polymer PET is polyethylene terephthalate, which is the same as the photosensitive film, but the photosensitive characteristics are different.

X-rays generally have the following characteristics:

1, high resolution, improving the ability to identify defects.

2. High sensitivity to X-rays, especially medical X-rays, is required to minimize X-ray radiation and prevent human body from being hurt.

3, convenient use and simple processing.

4. The film should be evenly coated without stains, so as not to be confused with trapped images.

5.X-ray film must be coated with high-sensitivity Gao Fancha blind color emulsion on both sides of the film base, so as to improve the utilization rate of X-ray and enhance the image contrast.

Extended data

X-rays are mainly divided into medical X-rays and industrial X-rays according to their uses. Medical x-rays use light blue film base to prevent halo. When in use, you can also add a fluorescent sensitizing screen to stimulate fluorescence shooting, and the effect is better.

Industrial X-rays need particles, low fog, Gao Fancha, high density and high resolution. In addition, there are radiation measuring films for measuring radiation dose, and in a broad sense, they also include films for X-ray photographic reproduction. Usually, both sides of the film base are coated with emulsion for direct photography to improve the sensitivity and contrast.
