  • Radiation source rate estimation through data assimilation of gamma dose rate measurements for operational nuclear emergency response systems

    This paper presents an evaluation of an innovative data assimilation method that has been recently developed in NCSR Demokritos for estimating an unknown emission rate of radionuclides in the atmosphere, with real–scale experimental data. The efficient algorithm is based on the assimilation of gamma dose rate measured data in the Lagrangian atmospheric dispersion model DIPCOT and uses variational ...

  • Evaluation of detection abilities of monitoring networks using multiple assessment criteria

    The problem of evaluation of radiation monitoring network quality is considered. The comparison of possible network configurations is performed on simulated experiments where a twin model is used to simulate observed data. An assimilation procedure based on the particle filter approach is run for each configuration of the network. Specifically, multiple realisations of segmented Gaussian plume ...

  • Calibration and characterisation of extremity dosimeters

    The increasing use of radiation in the medical field is providing great advances in health improvement. However, these techniques can generate an increase in the number of professionals exposed to radiation. The Brazilian authorities (Brazilian Nuclear Energy Commission ? CNEN) have imposed the monitoring of specific body parts of professionals. One of these obligations is the monitoring of the ...

  • Development and production of holders for extremity detectors

    The objective of this paper was to develop and produce holders for thermoluminescent detectors for use in interventionist radiology and nuclear medicine. To obtain the value of Dose Equivalent for Extremities, a dosimetry of extremities was done. The holders must have characteristics which are adequate for their intended use. The detector element used in the holders was the LiF:Mg,Ti (TLD-100) ...

  • Photoelectrocatalytic disinfection of water and wastewater: performance evaluation by qPCR and culture techniques

    Photoelectrocatalytic oxidation (PEC) was evaluated as a disinfection technique using water and secondary treated wastewater spiked with Escherichia coli and Enterococcus faecalis. PEC experiments were carried out using a TiO2/Ti-film anode and a zirconium cathode under simulated solar radiation. Bacterial inactivation was monitored by culture and quantitative ...

  • Case study - Anglian water Cryptosoridium outbreak

    Pitsford Drinking Water Site, England In June 2008, a rabbit was located in the wash water tank at the Pitsford Drinking Water Plant of Anglian Water, leading to contamination of the treatment works with Cryptosporidum, a chlorine resistant parasitic micro-organism. The parasite was detected on June 24 and, following consultation with health and local authorities, a notice to boil ...

  • The CaroMont Health Ozone Laundry System

    Abstract Ozone generating equipment was retrofit into the laundry washroom of the Gaston Memorial Hospital in Gastonia, NC, and began operating in the early part of July, 2010. Three ozone generating systems service six washer-extractors in the washroom. The performance of this fine-bubble ozone diffusion laundering system has been monitored since that time, with various adjustments made ...

  • Q&A: Patrick Wagnon on glaciers and climate change

    Patrick Wagnon is a glaciologist at the Institute of Research for Development in France, and a visiting scientist at the International Centre for Integrated Mountain Development in Kathmandu, Nepal. As a global ‘glacier chaser’, he has summited some of the highest mountains in the world, including the 8,516 metre Lhotse in the Himalayas. In 2001, Wagnon and his fellow glaciologist ...
