1. The NIFA administers cobalt-60 radiation source , Near-infrared spectrometer and Ultraviolet visible spectroscopy. 2. For the latter it is desirable to have a strong radiation source . 3. Moreover, earth's natural radiation can easily mask a distant radiation source 's signal. 4. For the arising spectrum there had not been any conventional radiation sources beforehand. 5. Typically, these use Co-60 or Cs-137 isotopes as the radiation source . 6. The hazards from various astrophysical radiation sources were reviewed in 2011. 7. Their plan exposed, Ru'afo insists upon harvesting the radiation source immediately. 8. Many years ago, these radiation sources occasionally fell into molten vats. 9. Quantum Detectors was originally a spin out from the Synchrotron Radiation Source at Daresbury. 10. It is also used in radiotherapy as a radiation source , in particular in brachytherapy.
