Welcome to GammaWiki

GammaSem: Nordic seminars for users of gamma spectrometry

GammaWiki is a product of the NKS-B GammaSem activity

The activity involves two seminars for users of gamma spectrometry, one was held in 2009 and the second will be held in the autumn of 2010. The seminars focus on practical challenges in gamma spectrometry. Users of gamma spectrometry from Nordic countries are invited.

The GammaSem seminars provide a forum for discussion and sharing of information on practical issues concerning gamma spectrometry and establishing a network of users of gamma spectrometry in the Nordic countries. The network strengthens Nordic collaboration between gamma spectrometry users, and improves competences in practical gamma spectrometry. The funding from NKS contributes to building such a network through contributing to the seminars and work to be done in the time period between them.

The new seminar: 28th-29th September 2010 at Kjeller, Norway

  • Dr. Lars-Erik De Geer will give a presentation about the fundamentals of true coincidence summing correction and when/why it is important
  • Presentations from work groups
  1. Presentations from individual participants (e.g. related to work in the work groups)
  2. Open discussions on future needs and how they should be addressed
  3. Possibility of workshops after the seminar

More information:

The 2009 seminar

The seminar in 2009 was attended by 75 participants from 34 organisations. Key issues for follow-up were identified and 6 working groups established on various aspects of gamma spectrometry. The working group topics are:

  1. uncertainties and detection limits
  2. true coincidence summing corrections
  3. Monte Carlo calculations
  4. absorption corrections
  5. mobile systems, and
  6. nuclear forensics.

The topics for the working groups form the basis for the seminar in 2010 where the groups will present results of their work and ideas/solutions to the problems. Each working group will contribute to the final report for the activity. The number of participants of the GammaSem activity has been expanded to include the working group coordinators.

The GammaSem working groups and participants will ensure contact between the gamma spectrometry users between and possibly after the seminars. The participants will organise a web site with a mailing list that will make it easier to contact Nordic colleagues on issues related to gamma spectrometry.
