Peter Sierck's Publications

  • Pilze

    • Electrosmog-Wohngifte-Pilze/ Haug Verlag Heidelberg
    • April 1999
    Authors: Peter Sierck

    Investigation, assessment and remediation of fungal problems in buildings. References to associated health concerns, investigation methods, laboratory analysis and practical remediation approaches.

  • Fungal Genera Identified from Flooded Wall Cavities

    • Bioaerosols, Fungi and Mycotoxins
    • December 1999
    Authors: Peter Sierck, Connie Jenkins

    Field investigations are often confronted with situations of evaluating whether or not fungal amplification is present inside a wall cavity. This study was conducted to assess if culturable air sampling of wall cavities is a viable tool to assist in making the determination. The analysis showed an increase in total colony counts and a significant shift from Cladosporium species to Aspergillus and Penicillium species in wall cavities which had sustained water intrusions.

  • HF-Radiation Levels of GSM Cellular Phone Towers in Residential Areas

    • EMF Conference Greece
    • 2003
    Authors: Peter Sierck, Thomas Haumann, Wolfgang Maes, Uwe Muenzenberg

    This study presents data related to GSM (Global System for Mobile Communications) cellular phone radiation resulting from antenna sites and towers inside residential areas in Germany. A statistical evaluation of over 200 representative high frequency field measurements is presented for the years 2001 and 2002. The results show that, especially for future cellular UMTS (Universal Mobile Telecommunications System) applications, there are several options to minimize additional HF radiation exposures for the population and reduce the potential risk for exposures.

  • Nonstop Pulsed 2.4 GHz Radiation Inside US Home

    • EMF Conference Greece
    • 2003
    Authors: Peter Sierck, Thomas Haumann,

    The use of DECT (Digital Enhanced Cordless Telecommunication) cordless phones has been a major health and environmental concern in Europe and especially in Germany for years. The biological concern arose from studies on HF (high frequency) sources such as GSM cellular phones and towers. Digital cordless phones are also available in the USA – marketed as 2.4 GHz digital technology. A digital cordless phone was placed in a representative private home in California and HF measurements were conducted at different locations inside, using frequency selective spectrum analysis to obtain the cordless phone power densities. The results showed that the radiation patterns and levels emitted by the small cordless phone base station are almost identical to the DECT technology – also digitally pulsed and permanent microwave radiation. The power density values presented for each room inside the home can be compared to average DECT cordless phone radiation exposures found in German homes. The maximum power density was found to be over 500,000 µW/m2 at a normally encountered distance (about 1 - 2 feet) if the base station is placed on an office desk or bedside table. The radiation peak values in the same room are higher than those encountered in proximity to cellular base stations located near residential buildings.
