| + | ==Welcome to GammaWiki== |
| | + | 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. If you wish to read about GammaSpec 2016, you can do so [[GammaSpec 2016|here]]. The [[GammaSpec 2017]] workshop was held in September 2017 in Risø. Read all about [[GammaSpec 2017|here]]. Here you can find a link to the [[GammaRay 2018|GammaRay 2018 site]] and here to the [[GammaRayX 2021|GammaRayX 2021 site.]]. |

| − | <big>'''NKS-B GammaWorkshops: Nordic workshops for users of gamma spectrometry'''</big>
| + | ==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. |

| − | == GammaWorkshops 2012 - September 11-12, Hótel Örk, Hveragerði, Iceland ==
| + | 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. |
| | | | |
| | | | |
| − | '''A follow-up on issues identified at the two NKS [[#GammaSem: Nordic seminars for users of gamma spectrometry|GammaSem seminars]], held in 2009 and 2010; and the GammaWorkshop held at Risø National Laboratory for Sustainable Energy, Roskilde, in 2011'''

| − | | |
| − | The previous workshop and seminars have aimed at focus on topics of relevance for the participants, including methods for corrections and calibrations in gamma spectrometry. The feedback has been positive, last year one of the participants in the workshop commented that it had been the '''''"most interesting and useful workshop ever attended".'''''

| − | | |
| − | The accident at the Fukushima NPP 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. The previous workshop in 2011 highlighted some of the challenges of sampling and measuring soil cores. This time there will be presentations on gamma spectrometric in-situ measurements as an alternative to soil core measurements. This can be important, especially for assessing contamination of large areas.
| |
| − |
| |
| − | The form of the GammaWorkshops is to enable 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, theory and practice'''
| |
| − | #'''Alternative types of detectors'''
| |
| − | #'''Background components in gamma spectra'''
| |
| − | #'''User experience with new techniques'''
| |
| − |
| |
| − | Lecturers at the seminar will be Dr. '''Sandor Tarjan''', Dr. '''Tim Vidmar''', Dr. '''Andrew Tyler''', Dr. '''Gerhard Fritz''', 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). Information on agenda and links to technical background material will be updated on this GammaWiki web site: https://www.gr.is/wiki/GammaWiki/
