Medical imaging professionals (diagnostic radiographers) are responsible for producing high quality medical images with various types of radiation to monitor and diagnose injuries and illnesses.
What Is Radiation?
Radiation, taken from the Greek “radius” (meaning beam of light) is the outward emission of energy from a central source.

Radiation Sources
Radiation is, and always has been, a natural part of our environment. Consequently, a range of different sources – both natural and man-made – contribute to our exposure to ionizing radiation in daily life.

Benefits and Risks of Radiation
It’s a natural conundrum! Being exposed to too much radiation can be harmful, if not lethal. On the other hand, without radiation, we wouldn’t benefit from the heat of the sun and life wouldn’t exist as we know it.

History of Medical Radiation
X-rays were discovered by Wilhelm Röntgen in 1895. Within six months, they were being used to locate bullets in wounded soldiers and today they form the center of many areas of medical diagnosis and treatment.
