The total amount requested was 7817 kDKK from an expected budget of 3400* kDKK.



NKS-B Call for Proposals 2015


13 proposals for NKS-B activities were received before the deadline on October 15th. Of these, 6 were applications for continuation of ongoing activities.


The numbers of proposals submitted under the NKS-B areas of interest are as follows:


Area of Interest

No. of Proposals

Total budget for proposals

under area of interest

Emergency Preparedness


1780 kDKK

The total amount requested was 5130 kDKK from an expected budget of 3400* kDKK.


*Note: the expected budget for each programme has been reduced from the previously announced 3750 kDKK to 3400 kDKK due to unforeseen substantial changes in inter-Nordic currency exchange rates at the end of 2014.  



Recent Seminars


NKS-R Nordic-Gen4

Nordic-Gen4 seminar 

4-5th September 2014, LUT, Lapeenranta, Finland

This was the 5th Nordic Seminar on Generation IV Nuclear Reactors. The Nordic-Gen4 seminars provide a forum for addressing current issues and perspectives related to Generation IV Nuclear Reactors. The seminar covered a wide range of Generation IV technologies with presentations on reactor concepts, research efforts and research results. The presentations can be found here:

Workshop on Gamma Spectrometry 

7-8 October 2014, Helsinki, Finland 

The NKS-supported GammaUser 2014 workshop was the sixth meeting of the successful GammaSem series of workshops and seminars on gamma spectrometry. 

There were about 35 participants from different Nordic and European organisations.  Attendees were encouraged to participate in pre-workshop inter-comparison exercises (both with real spectra and physical samples), for which results were presented and evaluated at the seminar. 

The program offered presentations from a diverse set of users of gamma spectrometry and participants gave short presentations on the specific challenges their use of gamma spectrometry entails. In addition, lectures were given by highly qualified invited speakers: 

Tim Vidmar, SCK•CEN, and Marie-Christine Lépy, Laboratoire National Henri Becquerel 

Students and young scientists in fields relevant to gamma spectrometry were particularly recommended to attend.

Seminar on Unmanned Radiometry Systems 

2-3 October 2014, Linköping, Sweden 

Linköping University, STUK, NRPA and NKS arranged a Seminar on Unmanned Radiometric Systems – SemUnaRS. Participants included experts and authorities from Sweden, Norway, Finland and Denmark, and a Swedish SME manufacturing unmanned airborne radiometric system platforms. 

The objective of this seminar was to present and discuss the progress of the Nordic use of unmanned platforms for radiation detection. This start-up seminar was an effort to build an inventory of the Nordic capacity of radiation surveillance equipment using unmanned vehicles and an initiative to build informal Nordic networks within the topic in question. 

Topics for presentations and discussions included: Unmanned platforms, Detectors, Air sampling using unmanned systems, Envisaged applications/scenarios for unmanned radiometry, Methods and strategies, Calibration/validation, Demonstrations, Joint exercises and Future Nordic collaboration. 

The use of unmanned systems in radiation detection is an area in which no joint Nordic activities have previously been established. The technology of unmanned systems has now developed to the point of readiness which enables their exploitation in different safety- and security-related applications.

Seminar on thyroid I-131 monitoring capacity in the Nordic countries 

29 September 2014, Copenhagen, Denmark 

This one-day seminar followed up on the results of the NKS-B THYROID activity, which comprised an extensive calibration program and proficiency test for thyroid monitoring instruments in the Nordic countries.  There were 31 participants from 21 institutions in Nordic countries.   The seminar was aimed at stakeholders from laboratories, hospitals, emergency preparedness and governmental organization etc. 

Results of the comprehensive THYROID NKS activity from 2013 were shared and discussed. Presentations and discussions took place relating to thyroid screening and emergency preparedness, and differences and similarities in Nordic preparedness organisations.  Dr. George Etherington from PHE, UK gave a lecture on dose assessment and the use of the IMBA internal dose model.  A problem was identified from a questionnaire as lack of consistency in calculation methods for internal dose (leading to the CfP 2015 proposal entitled IDEA). 

The organizing group consisted of: NIRP/SIS (DK): Henrik Roed, Asser Nyander Poulsen;  SSM (SE): Lilian del Risco Norrlid. NRPA (NO):   Bjorn  Lind;  IRSA (IS): Óskar Halldórson. Göteborg Uni. (SE): Mats Isaksson. Further information can be obtained from Henrik Roed ( or Asser N. Poulsen (
