Because different parts of the human body have different radiation paths through tissues, the radiation intensity used in the examination is different. When exposed to light, radiation passes through the subject before it reaches the film. When using the X-ray grid, the X-ray grid is between the subject and the negative, because the X-ray grid can be entered correctly.
For children, they are less tolerant, so try to reduce the dose as much as possible. Generally, X-ray grids are not used. For older children and adults.
