Welcome to GammaWiki


NKS-B GammaWorkshops: Nordic workshops for users of gamma spectrometry

A series of linked workshops on gamma spectrometry, 26-28 of September 2011, Risø National Laboratory for Sustainable Energy, Roskilde, Denmark

A follow-up on issues identified at the two NKS GammaSem seminars, held in 2009 and 2010

The GammaWorkshop is hosted by Risø DTU and information on how to get there is found at http://www.risoe.dtu.dk/en/meet_us/Vejviser.aspx.

The GammaWorkshops enable users to address the problems in gamma spectrometry they find most pressing, through lectures and practical exercises in addition to sharing their experience with others. The topics covered by GammaWorkshops are:

  1. Matrix and absorption corrections
  2. True Coincidence Summing (TCS) corrections
  3. Natural radionuclides
  4. Uncertainties and detection limits

It is possible to attend all the sessions or just some of them. The lecturers/instructors include leading expert in the field, Dr. Menno Blaauw (True Coincidence Summing corrections), Dr. Gerhard Fritz (implementation of Cascade Summing Correction in Canberra's Genie-2000), Dr. Tim Vidmar (matrix and absorption corrections), Dr. Kaj Heydorn (ISO-11929:2010) and Dr. Tuukka Turtiainen (natural radionuclides). More to be confirmed.

Participants are encouraged to bring their own computers, with the software they use for gamma spectrometry. In some of the sessions data for demonstration and practice will be distributed, in some software will be distributed as well.
