  • Got Survey Meters - How About Carbon -14 & Tritium Survey Meters?????

    Now show me your Carbon-14 and Tritium survey meter. Ooops, don’t have one? Regulatory Guide 1.21 defines a principal nuclide as any radionuclide whose concentration exceeds 1% of its total release. It states that the released quantity must be included in the Annual Radioactivity Discharge Report. For many U.S. nuclear power plants Tritium and C-14 have ...

  • Deep utility survey application

    Introduction Deep utility surveys are in most cases a nightmare to any GPR operator. The fact is that most of the utilities are in urban areas where there is a high amount of EM noise sources. Usually it is a complex net of entangled utilities, buried trenches and shafts that needs to be recorded and interpreted. The deeper one has to go, the harder it is to collect good quality data ...

  • Estimating soil conductivity for GPR surveys

    The results of a ground penetrating radar survey depends on many factors. In order to get useful data and good penetration, one of the conditions is that the conductivity of the ground is not too high. The conductivity of the material together with the operating frequency and the dielectric constant allow us to calculate the loss factor that is used to roughly estimate the theoretical ...

  • Surface-point resistivity survey case study 1

    Surface-points electrical resistivity surveys area can be used to detect one or several known underground anomalies in timely manner. A minimum of one borehole is needed to carry out Surface-points electrical resistivity surveys. A FlashRES electrical resistivity meter allows users to position active electrodes anywhere they want in the borehole, by conducting the survey in a surface-borehole ...

  • Surface resistivity survey case study 1

    The purpose of this surface electrical resistivity survey was to delineate the event direction of a gold ore deposit. The surface electrical resistivity survey uses a 10m interval cable, that permits the FlashRES 61 channel resistivity meter to detect depth up to 120m. The depth is dependent on the cable length.  The system found an occasional resistive band from 0-350m. This knowledge was ...

  • Micro-component survey of residential water consumption in Hanoi

    Daily total water consumption per capita has been used as a basic unit for the future planning of water supply for domestic use. However, for innovative water utilization designs that consider various scenarios, including the effects of policy direction and global warming, and more strategic and efficient water use, it is absolutely essential to consider water usage divided by residential ...

    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 ...

  • The exploration depth of FlashRES resistivity meter

    The formula for calculating the maximum depth is universal for all resistivity meters. The exploration depth depends on the survey line length. the survey depth is usually 20-25% of the survey line total length. For example, for 10m takeout cables, the total length of the cable is 10m*63=630m and this means the exploration depth is 0.2*630m to 0.25*630m. The resolution is 10% of ...

  • The key advantages of FlashRES resistivity meter

    FlashRES-UNIVERSAL is the first instrument in the world that can fully utilise all its electrodes during data collection.  It is a significant technological breakthrough. FlashRES-UNIVERSAL has following key advantages: FlashRES is a 61-channal resistivity/IP system and it is extremely fast For each current injection, conventional resistivity systems usually collect ...

  • Compare popular resistivity meters with FlashRES

    Although most resistivity meters nowadays can collect resistivity, IP and SP data and most of these systems are multi-channal resistivity meters, there is still a technical gap between traditional and next generation resistivity meters. FlashRES has six to 8 times more channel than traditional system, this means larger data quantity, which could help the resistivity inversion image ...
