In 1947, science firmly established that the earth was 3.4 billion years old.Finally in 1976, it was discovered that the earth is "really" 4.6 billion years old… The answer of 25 million years deduced by Kelvin was not received favorably by geologists.In medicine, projectional radiographs and computed tomography images are generally use X-rays created by X-ray generators, which generate X-rays from X-ray tubes.A number of other sources of X-ray photons are possible, and may be used in industrial radiography or research; these include betatrons, and linear accelerators (linacs) and Synchrotrons.
