The open data online service of the Radiation and Nuclear Safety Authority, Finland (STUK) provides the measurement data from the automatic external radiation monitoring network maintained by STUK and the measurement data of the radioactivity monitoring of outdoor air. The online service was implemented in cooperation with the Finnish Meteorological Institute.

At the first stage, the open data online service will provide the measurement data of the dose rate of external radiation starting from 2010 and the measurement data of radioactivity monitoring of air starting from 2008. The materials will be provided in a machine-readable format.

Members of the public and businesses can search for measurement data produced by these surveillance programmes from the service for their own or commercial purposes.

The objective is to gradually increase materials opened through the online service with the measurement data from the thematic investigations of the environmental radiation surveillance programme.

The technical implementation of the service was realized by the Finnish Meteorological Institute which opened their own open data portal in 2013. In addition to the STUK materials, the online service will have an extensive selection of data materials from the Finnish Meteorological Institute, such as meteorological observation and forecast data.

Monitoring of external radiation

The level of external radiation is monitored with an automatic radiation monitoring network consisting of about 250 measurement stations around Finland. The measurement stations measure the dose rate of external radiation in ten-minute intervals.

In Finland, background radiation normally varies from 0.05 to 0.30 microsieverts per hour. The monitoring network has two main purposes. To alert if the dose rate of external radiation exceeds the station-specific notification limit and to produce a real-time radiation situation overview of Finland.

Monitoring of radioactivity in air

In Finland, the radioactivity of outdoor air is monitored in eight cities: Imatra, Ivalo, Helsinki, Jyväskylä, Kajaani, Kotka, Rovaniemi, and Sodankylä. The monitoring stations pump large quantities of air through a filter collecting radioactive substances.

Filters are changed every 3–7 days, after which the substances collected in the filters are analysed in a laboratory.

The open data online service of STUK meets the requirements of the Inspire directive. These include metadata, spatial data, and online services, such as the catalogue and the review and downloading interfaces. Open data should be distributed in accordance with the Open Geospatial Consortium standards.

Open data on STUK website

The STUK website will provide more detailed information on the service and the opened materials (in Finnish).

STUK is developing the online service on the basis of the usage needs of data materials and the feedback from users. This is why registration is required in order to use the search service.
