  • 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, ...

  • ´More Stations. More Data. Better Forecasts.´ – the NYS Mesonet

    “More Stations. More Data. Better Forecasts.” – that’s the slogan of New York State Mesonet. The weather observation network consists of a total of 125 weather stations all over the state of New York and Lufft was selected as one of the vendors to support them in capturing the data. All 125 of the weathers stations have the standard instrumentation suite. Of those 125, 17 ...

  • Instrument selection and use for measurements in a radiological emergency

    A discussion of monitoring during a radiological emergency response is presented. This paper focuses on a response for the USA, but many principles would also apply for other countries. This paper starts with a discussion on instrument selection and preparation. Different scenarios based on materials involved and responder levels are presented with equipment concerns for each. This paper ...

  • 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 ...

  • 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. ...

  • A study of radiation shield effectiveness

    A brief comparison of temperature readings in two passively-ventilated and three fan-aspirated radiation shields under conditions of low wind and relatively high insolation is presented. From each of two periods of study, two days were chosen for conditions of high insolation and low wind to illustrate a reasonable sample of the performance of the shields. A single sample of each shield was used ...

  • 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 ...

  • Measurement uncertainty

    The IAEA/WHO Network, through Secondary Standards Dosimetry Laboratories (SSDLs) designated by the Member States, provides a direct linkage of national dosimetry standards to the international measurement system (SI, for Système International). Through the proper calibration of field instruments by the SSDLs, these measurements are traceable to the Primary Standards Dosimetry Laboratories (PSDLs) ...

  • Noise Measurement

    Definitions Threshold and criterion levels The threshold level is the A-weighted sound level at which a personal noise dosimeter begins to integrate noise into a measured exposure. For example, if the threshold level on a sound level meter is set at 80 decibels (dB), it will capture and integrate into the computation of dose all noise in the employee's hearing zone that equals or exceeds 80 dB. ...


  • Measuring of the Sunshine Duration

    The WMO (World Meteorological Organization) defines the Sunshine Duration as the time during which the direct solar radiation exceeds the level of 120 W/m2.   The DeltaOHM sensor LPSD18, performs the measure of radiation with an array of photodiodes arranged in a particular geometry which allows to obtain an accurate measurement in any ...

  • Performance-Based Measurement Systems

    Many of the Environmental Protection Agency's (EPA's) methods used to monitor air, water and soil for environmental contaminants prescribe step-by-step details on how the chemical analysis must be conducted and prohibit any deviations or variations. The EPA has recognized that monitoring equipment and technology have improved tremendously over the last few years; that environmental media do not ...

  • Present Status and Future of Advanced Scientific Instrument using X-ray

    X-rays have attracted a lot of attention as a form of electromagnetic radiation that enable us to see objects through materials. And they are also a great contributor to clacification of physical phenomena. In the field of analysis, X-rays have drawn attention from their initial stage as a method of non-destructive simultaneous anaysis. Scientific measurement using X-rays is supported by three ...
