# Timestamped list-mode data from coincidence γ-ray spectrometry with HPGe detectors on air-filter samples

## TL;DR

This paper presents raw data from γ-ray spectrometry experiments using HPGe detectors on air filter samples to study radionuclide detection.

## Contribution

The dataset introduces timestamped list-mode data for testing multi-fold coincidence spectrometry on real-world air filter samples.

## Key findings

- The dataset includes data from an air filter sample, a blank filter, and a spiked filter for comparative analysis.
- The setup uses five HPGe detectors, including one with a BGO Compton suppression shield for improved detection.
- The data supports research into reducing the minimum detectable activity of anthropogenic radionuclides.

## Abstract

This data set contains raw timestamped list-mode data obtained using an array of HPGe detectors for the purpose of testing coincidence spectrometry in the context of measurement on air filter samples. Data from one air-sampling station managed by the Swedish Defense Research Agency (FOI) is made available. This air-sampling station is located in Umeå, Sweden (Latitude 63.85°N, Longitude 20.34°E, 46 m above sea level). In addition to the air filter sample, data from a blank filter as well as a filter that was spiked with a known activity of radionuclides is made available in this data set. The detector setup used to collect this data set is made up of five individual HPGe detectors, with one of them surrounded by an active BGO Compton suppression shield. The data set provides a testing ground for investigating the use of multi-fold coincidence spectrometry as a tool to lower the minimum detectable activity of anthropogenic radionuclides in air filter samples.

Access to this data set allows researchers to explore and evaluate analysis methodologies for coincidence γ-ray spectrometry on real samples.
