GammaWiki is a resource webpage for Nordic users of gamma spectrometry. This work is supported by the [http://nks.org Nordic Nuclear Safety Research] (NKS). GammaWiki is a product of the NKS GammaSpec 2016 activity, which is an independent continuation of the [[GammaUser 2014|GammaUser (2014)]], [[GammaTest 2013|GammaTest (2013)]],  [[Gw2011 programme|GammaWorkshop (2011-2012)]], and GammaSem (2009) activities.

Interaction between practitioners in gamma ray spectrometry in the Nordic countries, was once sparse and fragmented. A group of practitioners of gamma spectrometry decided to organize a meeting to bring together experts in the Nordic region for conversation and sharing of experiences. They successfully applied for support from the NKS, and the first GammaSem activity was started in 2009. The response was strong, and the meeting became a great success.

The GammaWorkshops activity enables the 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 in a similar position. 
 
The main topics are:
 
#'''Lessons learned from Fukushima including work on real spectra'''
 
#'''In-situ gamma spectrometry demonstrations'''
 
#'''Other types of detectors'''
 
#'''Background components'''
 
#'''User experience with new techniques'''
 
 
Lecturers at the seminar will be Dr. Sandor Tarjan, Dr. Tim Vidmar, Dr. Andrew Tyler, Dr. Annika Tovedal and  members of the GammaWorkshops working group.
 
 
The programme is being prepared by a working group consisting of: Elisabeth Strålberg (IFE), Sigurður Emil Pálsson (IRSA), Henrik Ramebäck (FOI), Sven P. Nielsen (DTU/Risø) and Seppo Klemola (STUK). Updated information, detailed agenda and links to technical background material will be available on this GammaWiki web site:  https://www.gr.is/wiki/GammaWiki/
 
 
Details concerning hotel reservation and transport between Keflavik/Reykjavik and Hveragerði will be given at the GammaWiki web site.
 
 
In order to facilitate planning, we would appreciate if those interested in participating would fill out and return the enclosed registration form as soon as possible. Deadline for proposal is 2012-xx-xx.

Welcome to GammaWiki

GammaWiki is a resource webpage for Nordic users of gamma spectrometry. This work is supported by the Nordic Nuclear Safety Research (NKS). GammaWiki is a product of the NKS GammaSpec 2016 activity, which is an independent continuation of the GammaUser (2014), GammaTest (2013), GammaWorkshop (2011-2012), and GammaSem (2009) activities. If you wish to read about GammaSpec 2016, you can do so here. The GammaSpec 2017 workshop was held in September 2017 in Risø. Read all about here. Here you can find a link to the GammaRay 2018 site and here to the GammaRayX 2021 site..

Background

Interaction between practitioners in gamma ray spectrometry in the Nordic countries, was once sparse and fragmented. A group of practitioners of gamma spectrometry decided to organize a meeting to bring together experts in the Nordic region for conversation and sharing of experiences. They successfully applied for support from the NKS, and the first GammaSem activity was started in 2009. The response was strong, and the meeting became a great success.

For information on past seminars, see our Past meetings page.

The accident at the Fukushima NPP in 2011 highlighted many challenges in modern gamma spectrometry, such as dealing with complex spectra not encountered on a routine basis, application of appropriate corrections (such as true coincidence summing), estimation of ground contamination and radionuclide concentrations in soils in general.
