Radiation Safety
From WikiMSK
X-rays are on the electromagnetic spectrum, they are massless particles that travel at the speed of light. They have a very short wavelength which gives it certain properties. You can't see it, it passes through things, and it ionizes all matter. In a biological system it can give rise to unwanted effects. The x-ray scatter is very similar to visible light scatter. Think of x-rays of short wavelength light that is ionizing. Every x-ray machine uses the same fundamental method of producing x-rays. It is measured in volts (kVs), and milliamps.
