Data availability

Are data archived or planned to be archived at an AMAP Thematic Data Centre?
Data centres
Radioactivity TDC
If no (or only part of data are reported to a TDC), where and how are (other) data stored?
All data is stored at STUK and the main time series are stored at radioactivity TDC. Some of the data has been used in publications. Data can be obtained by a request from the project leader.

Samples/specimens archived in specimen banks?
Specimen banking information

No speciment banking.

Methods & Procedures

Procedures and methodology used for, e.g., sampling and sample storage, sample pretreatment, extraction and analysis, including which laboratories are involved, references to methods employed, etc.

Samples are mainly delivered to the laboratory by the e.g. reindeer herders.

QA/QC Information (what QA/QC procedures are implemented, laboratories involvment in QA/QC activities, model verification/validation routines, etc.)

Participation in proficiency tests such as NPL PTE.

Additional Information

Is this a bi- AND multi-lateral project (i.e. a project involving cooperation between different countries)?
Other institutes involved in the project

Generally no other institutes are involved. However, some data sharing have been practised with research group in the University of Eastern Finland.

Is this project reporting to other organizations/programmes?
