| − | 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 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. |

| |
| − | | |
| − | === 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.
| |
| − | | |
| − | '''Weather update:''' The autumn has arrived and the only thing that is predictable about the weather is that it is unpredictable. Please remember warm clothing (if you want to wander outdoors), we could get temperatures down to zero. But I recommend remembering also the geothermally heated warm swimming pool the hotel has.
