11. The radiation source can be a gas chamber, filled with 86 Geiger Mueller counter. 12. A great number of such beamlines can emerge from modern third-generation synchrotron radiation sources . 13. If so, opening the case to replace the radiation source would vent the chamber. 14. Losses and thefts of radiation sources account for over 90 percent of these accidents, 15. The remaining 20 % results from exposure to man-made radiation sources , primarily from medical imaging. 16. A wide variety of radiation sources are employed in order to cover the electromagnetic spectrum. 17. They are widely used in industrial water treatment, because they are very intense radiation sources . 18. Third-generation synchrotron radiation sources were conceived and optimized from the outset to produce brilliant X-rays. 19. Radioluminescence is also sometimes seen around high-power radiation sources , such as nuclear reactors and radioisotopes. 20. Photoemission spectra are also measured using synchrotron radiation sources .
