Radiology on Children: Less is Necessary !

Most everyone knows of the need for safety when having radiological imaging, such as X-rays(it is from mobile x ray machine or c arm  x ray machine when you are wounded ), done. Steps to protect against the low-level radiation involved with these procedures include the wearing of lead aprons and the extra precautions required for imaging pregnant women.
Additional vigilance and safety are also needed when it comes to the radiological imaging of children.
The individual risk from radiological imaging is quite small when compared to the benefits that it can provide through helping with accurate diagnosis. Still, unnecessary radiation exposure during medical procedures should be avoided. This is particularly important when the patient is a child.
Children may be more sensitive to radiation received from medical imaging scans than adults. One factor to consider is that children have more rapidly dividing cells that can be exposed to the low-level radiation. Also, they have a longer expected lifetime for the effects of radiation exposure to manifest as cancer.
That is why it is important that with children, the lowest radiation dose necessary is used for providing an image from which an accurate diagnosis can be made.
So the technology of x ray machine (mobile x ray machine , stationary x ray machine ) is promoting a lot . The x ray machine is high frequency , high voltage , high mAs,  microcomputer exposure control , microfocus point and so on . they all can reduce radiation from x ray machine a lot . Then people, especially children can get the benefit from x ray without worry.
