Based on the X-ray penetration, differential absorption, photographic effect, ionization effect, fluorescence effect and biological effects, X-ray has been applied to people's social life in various fields, such as industrial injury detection, medical diagnosis and treatment.
X-rays have a strong penetrating ability, in medicine, when irradiating the human body, due to the composition and density of the various parts of the human body tissues are different, so that the amount of X-ray penetration is different, when the remaining X-ray irradiation to the photographic film will be less penetration of the bone to form a clear picture.
2, the difference between CR and DR
