  • Radiation Monitors and Meters

    Light Description and Applications The light meter is a portable unit designed to measure visible, UV, and near-UV light in the workplace. (The CTC has a UV light meter available through its loan program, ALEP.) The light meter is capable of reading any optical unit of energy or power level if the appropriate detector has been calibrated with the meter. The spectral range of the instrument is ...

  • Ionising Radiation

    Introduction The energy level of some types of radiation is high enough so that when they interact with matter they cause the formation of electrically charged particles or ion-pairs and break molecular bonds. These so-called ionising radiations are by their nature potentially harmful to life; at high doses they can be lethal and at lower doses can cause genetic damage. Ionising radiation occurs ...

  • Aerial Radiation Detection

    In this time of multiple threats to our security: dirty bomb; cyber; shooters in public places; homemade bombs; misinformation; etc. we feel extremely vulnerable; perhaps more vulnerable than ever before. With the advent of Drone technology now available to private citizens, technology previously only held by the military, the opportunity has come to marry Drone Technology with aerial sensors. ...

  • Radiation dosage case study

    The Oak Ridge Associated Universities (ORAU) Team Dose Reconstruction Project assists the US National Institute for Occupational Safety and Health by reconstructing the radiation doses received by workers at various Department of Energy and Atomic Weapons Employer facilities. This work involves personal interviews with claimants, retrieval and validation of individual monitoring data, ...

  • Non-Ionising Radiation

    Pressures on the environment may occur through chemical, physical and biological agents. The subject of this study is physical agents, where physical fields are examined. Physical fields are part of the natural environment. Depending upon their properties and the surrounding conditions, physical fields are transmitted through the spaces in which we live, potentially affecting human health and ...

  • Why is there no effective real-time Continuous Radiation Monitoring System?

    Japan's disaster has raised many questions regarding safety of the public. It has served as a wakeup call to the agencies tasked with protecting the public. Not least of these questions, but certainly the most far-reaching is the question of the safety of nuclear power and radiation contamination of air and water. Way back when nuclear power was first established, in the 1960s public opinion was ...

  • Effective use of radiation monitoring data and dispersion calculations in an emergency

    An essential prerequisite for the proper management of a radiation emergency is that measurement data and calculation prognoses are available and that they are produced in an efficient manner. This paper reviews some of the factors contributing to the practice of performing radiation measurements and atmospheric-dispersion-model calculations effectively and discusses the issues related to the ...

  • Radiation Water Monitor in Real-Time and Continuous at Jefferson NL 2006

    Jefferson National Laboratory is a high tech laboratory located on a beautiful campus in suburban Virginia. Their research is centered on their high-energy electron accelerator. Energies generated are as high as 6 Gev continuous with currents up to 200 micro Amps. Where does the high-energy accelerator beam go after smashing atoms in the experimental sample? It impacts into a tank of purified ...

  • Physical dosimetry system in radiation accidents

    We experience various types of radiation accidents. When a radiation accident happens, one of the important aspects that we have to consider is the radiation dose to the victims of the accident. To judge the health effects due to radiation exposure, it is necessary to make a dose assessment. There is a variety of dose assessment methods, of two types: biological dosimetry and physical dosimetry. ...

  • Brüel & Kjær’s radiation-resistant accelerometers

    Carrying out vibration measurements in harsh industrial environments is much easier for engineers with Brüel & Kjær’s new Type 8347-C Accelerometer. The Type 8347-C accelerometer can withstand temperatures ranging from -196°C (-321°F) to +482°C (+900°F) and has high resistance to radiation. The shear design ensures the accelerometer  superior thermal ...

  • The influence of microwave radiation on the behaviour of Rattus norvegicus

    The use of mobile phones has been the target of a great controversy due to possible biological and behavioural effects. This research presents a preliminary evaluation, regarding the learning and stress levels in subjects of the species Rattus norvegicus, submitted to microwave radiation. The psychological analysis was based on laboratory tests using the aquatic maze (tank of Morris), to ...

  • UV-radiation 1983–2003 measured at Norrköping, Sweden

    Total ozone has been monitored with high accuracy at many sites for a relative long period of time. This is not the case for UV. The main reason is that UV is difficult to measure accurately. Extensivemonitoring started first during the 1990s. However, there are some data series still in operation that were initiated at earlier dates. This paperwill discuss one such series from Norrk€oping, ...

  • An update of the probabilistic safety assessment of the Radiation Monitor Calibration Laboratory of a Brazilian nuclear power station

    In 2001, a probabilistic safety assessment of the Radiation Monitor Calibration Laboratory of a Brazilian nuclear power station was performed to estimate its radiological risk. Owing to the lack of data, many conservative assumptions were considered. The purpose of this paper is to obtain the updated laboratory radiological risk. A human reliability analysis of the procedure for calibrating the ...
