Xray is being used in the health industry as the most important tool to diagnose especially in orthopaedic speciality. Xray was a chance discovery by Roentgen in the year 1895. He had the acumen to understand the importance and potential of a chance discovery which is the hallmark of great men.
Xray comes with a rider, radiation… but thankfully it is very negligent. The radiation is measured in Millisievert(mSv).
In orthopaedics, Xray is used to diagnose treat and manage fractures. It is the most important tool of an orthopaedic surgeon. Now we have digital Xray where the quality and the contour are better, enhancing the diagnostic capabilities of the surgeon.
Now we come to the most important question, How much of Xray is safe for a person in his lifetime?
Xray is generally measured or compared with normal environment radiation. The American College of Radiology recommends 100mSv in a lifetime which is equal to 10000 chest Xrays or 25ct chest scans. A standing chest Xray is 0.1mSv.
From this, we can safely conclude, an average healthy individual can safely take as many Xrays as possible in his lifetime, Surmising the maximum of 10000 usually will not be surpassed.
