Project Goal

Our project's goal was to update our GIS platform and consolidate all available GIS information into a single hub. We also wanted to automate the field collection of radiation measurement data. This includes manual measurements made by field measurement teams, as well as stationary and mobile automated measurement systems. This meant consolidating data from several measurement information storage systems, where location information was treated only as metadata to the actual radiation measurement information. We also wanted to use prognosis data on the dispersal of radioactive materials in an accident to focus our measurement capabilities on the most critical areas and to assist our field teams remotely in locating suitable measurement sites and assigning measurement tasks to individual teams.

The project was funded by the European Union through the Union Civil Protection Mechanism (UCPM).

Business Problem Solved

In a radiological incident or accident, the need for radiation measurements increases significantly. The personnel available to make and analyze the measurement results is limited. Consolidating and streamlining planning, data collection, and analysis of measurement information into a single hub frees up personnel resources for other tasks or lets them focus on the most important tasks at hand.

Company Overview

The Radiation and Nuclear Safety Authority (STUK) is responsible for supervising the use of radiation and nuclear energy in Finland.

We are an independent authority and expert organization. We provide people with objective radiation safety information so that they can understand what is hazardous and what is not.

STUK’s tasks also include preparing for exceptional situations that threaten STUK’s operations or affect our sector. We provide 24-hour emergency services for radiation hazards and act as qualified experts in hazardous situations.

Regarding radiation hazard situations, STUK supports other authorities and issues radiation-related recommendations for protection measures. STUK also plays an important role in preventing radiation hazard situations. STUK continuously monitors the situation picture, i.e., what is happening in Finland and abroad, and whether we need to take some action.

Return on Investment

- Enhanced data collection efficiency through ArcGIS Enterprise, combined with Field Maps and QuickCapture mobile applications.
- Enhanced data accuracy and quality. Collected data is automatically validated within the system, and tools can verify that location, time, attributes, and measurement data are correct.
- Better system performance and reliability. ArcGIS Enterprise servers and Notebook Server provide a scalable and reliable environment for storing, analyzing, and visualizing data. The system is designed to ensure high availability and continuous operation.
- Automation and Workflow Optimization: The collection, conversion to ArcGIS-compatible formats, and analysis of measurement data can be automated using Notebooks. This reduces manual work for experts and speeds up decision-making.
- Better decision support effectiveness. Collected and analyzed data is visualized in real time on dashboards and map views, supporting decision-making.
