Scattered gamma-rays

The effect is exploited in Mossbauer spectroscopy in which a gamma-ray source is mounted on a moving platform and a similar sample is mounted nearby. A detector measures gamma rays scattered by the sample. The source is moved slowly towards the sample at a varying speed, so as to continuously change the frequency of the emitted gamma radiation by the Doppler effect. A sharp decrease in the signal from the detector at a particular speed (i.e. frequency) indl-... [Pg.542]

There are several schemes for nondestructive evaluation. Changes in electrical resistance can be used to follow corrosion. Radiographic techniques involving X-rays and gamma rays have been applied. Transmitted radiation as well as back scattered radiation have been used. [Pg.19]

There are three methods of attenuating (reducing the energy level of) gamma-rays photoelectric effect, compton scattering, and pair production. [Pg.30]

Scatter occurs when the gamma ray photons emitted from the radionuclide in the lung encounter the thorax tissues and change the travelling direction from their origi-... [Pg.264]
