  • Analysis of Optical Bleaching of OSL Signal in Sediment Quartz 
    Przegiętka, Krzysztof; Chruścińska, Alicja (Elsevier B.V., 2013)
    The aim of this work was to study the effect of the quality of optical bleaching on the results of OSL (Optically Stimulated Luminescence) dating method. The large aliquots of coarse quartz grains extracted from fluvial ...
  • Chronostratigraphy of the Vistulian Glaciation (Weichselian) on the Kujawy Moraine Plateau (Central Poland) Based on Lithostratigraphic Research and OSL Dating 
    Przegiętka, Krzysztof; Chruścińska, Alicja; Oczkowski, Hubert Lucjan; Molewski, Paweł (Versita, 2008)
    The subject of the investigations presented here is fixing dilemmatic character (transgressive or recessive) of the Poznań phase of the Vistulian (Weichselian) Glaciation and answering the question about the possibility ...
  • Dosimetric features of strontium orthosilicate (Sr2SiO4) doped with Eu2+ 
    Barzowska, Justyna; Chruścińska, Alicja; Przegiętka, Krzysztof; Szczodrowski, Karol (Elsevier B.V., 2014)
    Thermoluminescence (TL) of strontium orthosilicate doped with Eu2+ has been investigated in the range RT- 750 K. Trap parameters of a TL peak at 450 K established by means of glow curve analysis suggest the possibility of ...
  • Luminescence from beta-Irradiated graphene layers 
    Chruścińska, Alicja; Przegiętka, Krzysztof; Szroeder, Pawel; Oczkowski, Hubert Lucjan; Rozploch, Franciszek (Instytut Fizyki PAN, 2006)
    We found that beta-irradiated samples of crystallite graphite and multi--walled carbon nanotubes emit light during heating above room temperature. This behaviour is rather surprising for semimetals. Due to the lack of deep ...
  • On application of low doses from beta radiation source in OSL retrospective dosimetry 
    Przegiętka, Krzysztof; Chruścińska, Alicja (Elsevier B.V., 2014-05)
    The paper reports on three levels of dose rates obtainable from single beta source: (133±3) mGy/s, (17.8±0.3) mGy/s and (1.94±0.04) mGy/s, as calibrated for quartz sand grains. These values were achieved for different ...
  • Quartz TL decay due to optical bleaching 
    Chruścińska, Alicja; Przegiętka, Krzysztof (WIND, 2005)
    In spite of many years of research our knowledge of the traps responsible for the OSL in quartz is not complete. Many papers report the complexity of this signal, determine its components and discuss their usefulness for ...
  • The relation between optical bleaching and sedimentological features of fluvial deposits in the Toruń Basin (Poland) 
    Weckwerth, Piotr; Przegiętka, Krzysztof; Chruścińska, Alicja; Pisarska-Jamroży, Małgorzata (Panstwowy Instytut Geologiczny, 2013-02-26)
    Distributions of equivalent doses (DE) obtained by the Single Aliquot Regenerative-dose (SAR) OSL method applied for large aliquots of coarse quartz grains extracted from fluvial sediments are presented and analysed with ...
  • Trap spectra of annealed quartz 
    Chruścińska, Alicja; Oczkowski, Hubert Lucjan; Przegiętka, Krzysztof (Institute of Physics, Polish Academy of Sciences, 1996)
    The trap energy density spectra of natural quartz were investigated by the fractional glow technique. The thermal treatment before excitation induces the changes of thermoluminescence sensitivity as well as the changes of ...
  • Using the TL Single-Aliquot Regenerative-Dose Protocol for the Verification of the Chronology of the Teutonic Order Castle in Malbork 
    Chruścińska, Alicja; Jesionowski, Bernard; Oczkowski, Hubert Lucjan; Przegiętka, Krzysztof (GADAM Centre, Institute of Physics, Silesian University of Technology, 2008)
    The Teutonic Order Castle in Malbork is one of the precious medieval monuments in Europe. Because of the lack of natural rock resources in Pomerania, its walls are built almost exclusively of bricks. The huge volume and ...
