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.
