Activity name GAMFAC: Advanced In-situ Gamma Spectrometry Field Activity - Chernobyl 
NKS-B Research Area Measurement strategies, technology and quality assurance
Project summary

In-situ gamma spectrometry is a field based analytical technique that forms part of the arsenal of most radiation protection/emergency reponse authorities. Technical developments over the past decade have resulted in practicable instrumental solutions to the problem of HPGe operation ourside of the lab. While theoretical and basic aspects of the application of such detectors can be addressed within a laboratory context, the full realisation of the technique is arguably hampered in many countries due to an absence of appropriate field sites for testing, calibration and method development. Such field sites should include relatively high levels of contamination, a range of isotopes, different soil types and depth profiles of contamination and include the prospect of being well characterised by laboratory based methods in advance.The GAMFAC activity intends to address such aspects of the problem by building on the practical experience and opportunities afforded by the NKS MOBELRAD activity of 2014. GAMFAC will conduct a series of field activities within the Chernobyl exclusion zone (Belarus side), at sites that have been precharacterised in relation to depth distributions, activities etc. These sites will offer a number of technical challenges to operators as well opportunities in relation to contamination levels and isotope suites that are impossible to replicate at other sites in Europe. In addition, GAMFAC will include the participation of a recognised expert in the field of in-situ measurements providing a unique training opportunity and technical exchange forum for participants from the Nordic countries.The primary focus of GAMFAC will be towards the development and practice of procedures and methods for effective in-situ measurements that move beyond the elementary case of surface deposited Cs-137.
