The GammaSkill 2023 seminar (September 27-28 2023) covers various aspects of gamma-ray spectrometry. The scope will be broad allowing a range of topics to be considered. The following areas could be included (but are not limited to):

*Laboratory, in-situ and mobile measurements
*Whole body measurements
*Uncertainty calculations
*Efficiency determination
*Spectrum analysis and data management
*Monte Carlo simulations
*Nuclear forensics
*Novel/new approaches
*Applications

The '''GammaSkill 2023 training event''' (September 26) is aimed at those having already some experience or basic knowledge on gamma spectrometry. The participation of students and young scientists is highly welcome.

International experts will be invited to the seminar to give presentations on different aspects and new developments in gamma-ray spectrometry. Participants of the seminar are encouraged to give presentations on subjects of their choice, describing their applications of gamma-ray spectrometry and possible challenges encountered, new developments in detectors, electronics and data analysis.

Name, organization, and e-mail address of the participants will be given only to the participants (if you accept it).

A seminar dinner will be arranged in the [https://www.heureka.fi/visitor-info/how-to-find-us/?lang=en Finnish Science Centre Heureka], which is located around 1 km from STUK and close to Hotel Vantaa.

There is no seminar fee.

==Presentations at the seminar and material==
The participants are encouraged to give presentations on subjects of their choice (15-20 min). We recommend attendees also to give “spontaneous” short presentations (5-10 min) on their work, see presentations of previous seminars.

We recommend that presenters send their presentations no later than September 18 2023 to Raisa Tiililä (see [http://halla.gr.is/wiki/GammaWiki/images/c/ca/Registration_form.pdf registration form)].

== GammaAI 2025 ==
 
Welcome to the GammaAI 2025 page of GammaWiki.
 
 
Here you will find information about the upcoming GammaAI 2025 seminar on gamma-ray spectrometry, taking place at '''DTU Lyngby Campus, Denmark, from October 8 to 9, 2025'''.
 
 
The seminar will introduce essential concepts of artificial intelligence (AI), aiming to emphasize potential practical applications within gamma-ray spectrometry. A dedicated session will provide introductory lessons on AI.
 
GammaAI 2025 will also cover a broad range of topics related to gamma-ray spectrometry. The seminar's scope is intentionally wide, allowing discussions on various relevant areas.
 
The following areas may be included (but are not limited to):
 
* Laboratory, in situ, and mobile measurements
* Whole body measurements
* Uncertainty calculations
* Efficiency determination
* Spectrum analysis and data management
* Monte Carlo simulations
* Nuclear forensics
* Novel approaches
* Applications
 
Participants are encouraged to join the data analysis intercomparison exercise using a soil sample '''[[#Data Analysis Intercomparison|(available here)]]''' and complete a survey regarding the lowest background levels they have achieved '''[[#Background survey|(available here)]]'''.
