Researchers are currently exploring the potential of a variety of technologies, including several based on detecting the release of Gamma Interferon in response to mycobacterium. ...
River water samples taken upstream and downstream from the power plants, drain water and overflow water were analyzed. In the water samples gamma spectrometry analysis was performed as well as determination of gross alpha and beta activity. Natural radionuclide 40K was detected by gamma spectrometry, while the concentrations of other ...
In this work, an activation technique was used for absolute neutron dosimetry. Induced gamma within two activation foils (115In and 197Au) was detected by (5 × 5) sodium iodide (NaI) crystal. ...
These methods are more comprehensive and sensitive than traditional passive methods for detection of neutron and gamma radiation from nuclear materials, such as U-235 and Pu-239. As a particular method for FM control we use a technique of differential die-away of neutrons, detected by He-3 proportional counters. Calculations performed for 60 ...
But up until the last year or two, it has been difficult to detect gamma emitters in water and impossible to detect or measure Alpha and Beta emitters in flowing water. ...
Food irradiation is the process of exposing food to controlled source of ionising radiation for the purpose of reduction of microbial load, destruction of pathogens and extension of product shelf-life. Detection and measurement of irradiation dose in food are an essential element of food safety and quality. This study aimed to estimate shelf-life of chicken samples which have ...
The CZT nanowires grown on semiconductor nanotubular TiO2 templates can be integrated into a detection device for sensing low-medium energy gamma rays.Keywords: electrodeposition, CZT, cadmium zinc telluride, band gap, resistivity, nanowires, gamma ray detectors, nanosensors, nanotechnology, ...
The helicopter systems are used for radiation measurements closer to the natural background levels.Keywords: aerial radiological survey, gamma ray detection, nuclear analysis techniques, data collection, aerial measuring systems, radiological emergency, emergency management, fixed-wing aircraft, helicopters, radioactivity, radiation measurements, emergency ...
The monitoring system, ModelSSS-33-5FT, was tailored to Jlab’s specifications and all detection specs were met. In addition to tritium detection this system has gamma detection of 1.0 E-5 to 1.0 E-01 uCi/mlfor Be-7 decay photons .435 to .55 MeV with good background gamma rejection. ...
Good overall agreement is found between measurement data and model results using the mesoscale atmospheric dispersion and dose rate model RIMPUFF.Keywords: aerosols, argon-41, BR1 reactor, gamma detection, optical radar, plumes, tracer ...
