X-ray frequency and energy is second only to gamma rays, with penetration, frequency range 30PHz~300EHz, corresponding wavelength of 1pm~10nm, energy of 124eV~1.24MeV. Let's take a look at the properties of X-rays.

Peculiarity:

1. Chemical characteristics

Photosensitivity: X-rays sensitize film as well as visible light. When the X-ray passes through the human body, due to the different density of the human body tissues, the absorption of the X-rayamount is different, and the sensitivity obtained on the film is different, so as to obtain the X-ray image.

Coloring effect: X-ray long-term irradiation of certain substances such as barium platinocyanide, crystals, etc., can make its crystals dehydrate and change color.

2. Biological characteristics

X-ray irradiation to the biological body, biological cells can be inhibited, destroyed and even necrosis, resulting in different degrees of physiological, pathological and biochemical changes in the body. Different biological cells, with different sensitivity to X-rays, can be used to treat certain diseases in the human body, especially the treatment of tumors.
