| + | ==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]].

| + | ==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. |

| − | 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. '''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/

| |
| − | The day before the workshop starts (on 10 September) there will be provided bus transport from Keflavík airport and Reykjavík to Hotel Örk, stopping at '''Hellisheiði Geothermal Power Plant''', Iceland's largest geothermal power plant, soon to be the world's largest.
| |

| |
| − | | |
| − | === Hotel Örk ===
| |
| − | The workshop this year will be held at Hotel Örk, Hveragerði, Iceland. It is located at the outskirts of the small town of Hveragerði, well known for being geothermally very active (in some areas you need to watch out when you walk, there are areas where the ground is really steaming).
| |
| − | | |
| − | The workshop rate for 2 nights is '''ISK 15.800 per night for a single room''' (this corresponds to ca. 100 € on 21 June 2012, please check [http://www.landsbankinn.com/#gengi exchange rates] which can change).
| |
| − | | |
| − | Please note that this is the TOTAL price for room with breakfast AND for use of conference facilities, lunch, morning and afternoon refreshments (sandwiches, cakes and fruits), coffee and tea which will be available at all times. Extra price for a 'superior' room is ISK 4000 per night. For an accompanying person sharing a room with a participant (but not taking part in the workshop) the added price is also ISK 4000 per night.
| |
| − | | |
| − | If you want to arrive earlier or leave later, the price for a single room for each night before or after the seminar is ISK 9900. This includes breakfast, but of course no lunch or other morning or afternoon refreshments. The hotel is within the southern lowland area and offers various possibilities for sightseeing, horse riding etc.
| |
| − | | |
| − | The workshop dinner Tuesday evening is arranged by the NKS-B GammaWorkshops.
| |
| − | | |
| − | Included in the room rate is access to all facilities at the hotel such as (geothermal) swimming pool, sauna, hot pools, golf course, billiard etc.

If requested when registering, the bus will also stop in Reykjavík (e.g. to pick up those who might have arrived earlier). '''Please indicate in your registration whether you want to make use of this bus service and whether it should be from the airport or Reykjavík'''.
