  • 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. ...

  • ´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 ...

  • GOOD NEWS FOR DRINKING WATER Independent Test Lab Evaluates Instrumentation forDetecting Radiation in Drinking Water

    Since 9/11 and there are still holes in security of the nation’s infrastructure, particularly for drinking water. This security deficit is currently being addressed in some community water systems with water monitoring instruments. In the 90s the EPA developed a wish list for monitoring contaminants in drinking water. Since that time biological and chemical contaminants have been identified ...

  • 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 ...

  • 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 ...

  • Radiobiology worker risk assessment using stress indicators and proteomics

    Radiology is an essential technology in medicine and is used for organ diagnosis, radio–tracing and radiotherapy. The risks for the radiobiology workers have not been assessed sufficiently because measuring instruments fail to detect very low doses. This paper presents an investigation on the potential risks for radiobiology workers, due to the occupational exposure to low doses of irradiation. ...

  • Safety in Drinking Water? Monitoring for Radioactive ContaminantsOnly Required Every Three, Six, or Nine Years per Federal Law

    Current federal law requires testing of drinking water for radionuclides, “hazardous radioactive materials” every three, six, or nine years. The states have the option to increase testing frequency. [Federal Register Year 2000; page 76746. http://www.gpoaccess.gov/fr/retrieve.html] An incident of terrorism, accident, or improper disposal ...

  • Time resolved liquid scintillation counting: (TR-LSC™) for environmental 3h analysis

    Environmental analysis of many naturally occurring and man-made, beta emitting radionuclides, including 3H, 14C, 90Sr/90Y, 241Pu, and 234Th is a significant analytical challenge due to the extremely low activity levels encountered. Under these circumstances, reducing instrument background is essential for improving analytical sensitivity. Time-Resolved Liquid Scintillation Counting (TR-LSC), a ...

  • Estimation of stand productivity from multi-angular optical remote sensing

    Global modeling of gross primary production (GPP) is a critical component of climate change research. On local scales, GPP can be assessed from measuring CO2 exchange above the plant canopy using tower-based eddy covariance (EC) systems. The limited footprint inherent to this method however, restricts observations to relatively few discrete areas making continuous predictions of global CO2 fluxes ...
