Check the patient's identity Note the image date and time Note the image projection: Check if a posterior anterior (PA) or anterior posterior (AP) projection was used, and note if the patient was standing, sitting or supine? Was the mobile X-ray machine used? The image annotations are often useful: This is a mobile chest X-ray taken with the patient supine, at 11.25 am in the resuscitation room. The patient's name, ID number and date of birth are annotated. Note the side marker is correct.

Time (reduce to a minimum the time you spend around an X-ray source) Distance(X-ray dose is inversely proportional to the distance squared) Shielding (aprons composed of metal that block x-rays) The three key elements of radiation safety
Slide 17-

X-ray can dislodge electrons from the shell of an atom. This results in the production of an ion (free radical is an unstable molecule with an extra electron. Free radicals become stable by donating their extra electron to other molecules within cells of the body. What can happen when people are exposed to radiation?
Slide 18-

This process permanently damages protein, DNA and other vital molecules. Among the ill effects reported from radiation exposure are birth defects, cancer and cataracts. Cont….
