Ultra low background gamma spectrometry enables researchers to measure and identify trace levels of radioactivity in samples.

​​

 

​The technique of gamma spectrometry using high sensitivity germanium detectors enables researchers to measure and identify trace levels of radioactivity in samples - an important and useful capability in a variety of studies from material selection in 'rare-event physics' to numerous studies of the environment.

Boulby currently operates a 2kg ultra-low background germanium detector for gamma spectrometry. Operating such a system deep underground, free of interference from cosmic rays, enables improved sensitivities of orders of magnitude compared to that achieved in surface facilities allowing the very lowest levels of radioactivity to be measured.

Participating institutions:

  • STFC Rutherford Appleton Laboratory
  • Sheffield University
  • Edinburgh University
  • Glasgow University
  • The Scottish University Environmental Research Centre (SUERC)
