- ‘It is known that when some materials are excited with nucleonic radiation, such as X-rays, the radiation is absorbed causing the material to emit characteristic radiation during the time of radiation absorption.’
- ‘The purpose of X-ray fluorescence is to determine chemical elements both qualitatively and quantitatively by measuring their characteristic radiation.’
- ‘The peaks of characteristic radiation of each element can be seen at their own places on the energy scale.’
- ‘In addition to the characteristic radiation, a continuous radiation spectrum of low intensity is produced ranging from a very low energy to the maximum kV-peak setting.’
