μDOSE System for Hazard Indices Estimation

Posted on by Maciej Gosek

A recent publication by Rocznik et al. (2023) demonstrated the μDOSE’s capability in accurately estimating various hazard indices (HI), including activity concentration index, radium equivalent activity, representative level index, absorbed and annual gamma dose rates, gamma effective indices, and both external and internal radiation hazard indices. This research highlights the new possibilities offered by the μDOSE system, particularly in measuring HI in small samples of just 3.00 grams. The estimation of HI was based on α and β particles, as well as decay pairs of 220Rn/216Po, 219Rn/215Po, 212Bi/212Po, and 214Bi/214Po. This method provided correlated radionuclide estimates. By taking this correlation into account, HI can be calculated with increased precision. The hazard indices measured were then compared with the results from high-resolution gamma spectrometry.

The μDOSE+ System is finally available

Posted on by Maciej Gosek

We’re thrilled to introduce our latest product – the μDOSE+ System.

This advanced, compact system is designed for high-precision assessment of ionising radiation’s dose rate in sediment and ceramic samples. Our upgraded device comes equipped with a triple scintillator, enabling low level accurate measurements. Unlike other α and β counting systems, the scintillator can be reused extensively, offering practically cost-free maintenance.

The μDOSE+ not only maintains key features of the original μDOSE, but it also introduces active shielding, significantly reducing background counts. This is achieved through state-of-the-art machine learning algorithms, making our system more precise and reliable.

One of the unique features of μDOSE+ is the integrated active 222Rn and 220Rn removal system, ensuring a clean, radon-free environment for accurate measurements.

Key advantages of our system include:

  • Compact size: W 22 cm x L 22 cm x H 34 cm
  • Triple scintillator integrated with machine learning algorithms
  • Improved counting chamber that provides higher counting efficiency
  • Active 222Rn and 220Rn removal system
  • Measurement time is typically 1-2 days for assessing dose rate
  • Comprehensive software enables dose rate calculations under varying conditions
  • Offers both installation and assistance for smooth operation

Researchers have published preliminary findings from their reinvestigation of the Kelly Forks Work Center Site (10CW34), an archaeological site located on the North Fork Clearwater River in the Nez Perce-Clearwater National Forest, Idaho. The site, which dates back to the late Pleistocene to late Holocene period, was previously thought to contain components associated with the Western Stemmed Tradition.

The researchers utilized μDose for assessing dose rates for trapped charge dating. This allowed to assess the stratigraphy and geochronology of the site, as well as to study traditional Nez Perce use of the Clearwater River drainage. Their findings provide new insights into the site’s history and cultural significance.

Further research is needed to fully uncover the site’s potential and deepen our understanding of the region’s prehistoric human activity.

New Interdisciplinary Study Uncovers Prehistoric Rural Settlement and Landscape Development in Northern Bavaria

Posted on by Maciej Gosek

A new interdisciplinary study on rural settlement and landscape development in northern Bavaria, Germany has been published. The study involved archaeological and geoarchaeological investigations supported by radiocarbon dating, optically stimulated luminescence dating (OSL), and palaeoecological analysis. The researchers aimed to identify unknown prehistoric rural settlement sites, determine site-specific soil erosion from colluvial deposits, and assess the composition of woodland from on- and offsite charcoal finds.

Figure adapted from Kothieringer et al. (2023).

The earliest evidence of human activities dates back to the Younger Neolithic period, while the Middle to Late Bronze Age (ca. 1400–800 B.C.E.) was marked by permanent rural settlement in a German central upland region. The researchers noted a peak in the Late Bronze Age, which they attributed to varying thicknesses of Bronze Age colluvial deposits, indicating land use practices that triggered soil erosion. The study also showed that Maloideae, ash, and birch were successional indicators after fire clearance during that period.

The settlement continued until the 5th century B.C.E, with a hiatus of 500 years before re-flourishing in the Late Roman and Migration periods (mid-3rd–5th century C.E.) and continuing into the Medieval period.

The study provides valuable insights into the prehistoric rural settlement and landscape development in northern Bavaria, and highlights the potential of OSL method with μDose measurements in archaeological research.

New Study Provides Absolute Dates for Artifacts from Lusatian Urnfield Cemetery at Brzezie, Greater Poland

Posted on by admin

Archaeologists have made a step toward uncovering the history of the Lusatian Urnfield Cemetery at Brzezie in the Pleszew region of Greater Poland. After many years of fieldwork, including geophysical prospecting and excavation, materials for radiocarbon and luminescence dating were collected to determine the absolute chronology of the site.

In a study four samples were dated using OSL. The luminescence dating was made possible by measuring the dose rates in small archaeological samples using the innovative uDOSE system. The results reveal an agreement between radiocarbon and OSL dating methods, providing a date range of 1000-500 BC.

This new study provides valuable insights into the history of the Lusatian Urnfield Cemetery at Brzezie and the uDOSE system helped to provide a more accurate estimate of the dose rates for OSL dating.
