X-RAY OVERVIEW
 

WHAT IS AN X-RAY
An x-ray produces light at a high frequency and short wavelengths. The high frequency of the light makes it easy to penetrate flesh. Once this high frequency light penetrates the body surface, it is absorbed by the bones. This allows the bones of the body to be photographed.

WHO DISCOVERED X-RAYS
Many scientists contributed to what is now called rsdiology. In terms of the actual discovery of the x-ray and x-ray diffreaction, C.G. Barkla, W.H. Bragg and W.L. Bragg must be given credit. In 1911 C.G. Barkla took the discovery of radiation from Bequerel and combined it with the knowledge of atoms discovered by Ernest Rutherford and Niels Bohr. This brought about the first stage in the evolution of x-rays.

DANGERS OF X-RAYS
X-rays have not evolved to a piont, that they are 100% safe. The reason for this is because the light that x-reays produce is ionising. In other words, x-rays break up different molecules into positive and negative ions. If this were to happen to cells in the body, they would die or not function in the manner they are supposed to. This would obviously be damaging to the patients health.
