A Comparative Study of Field Gamma-ray Spectrometry by NaI(Tl) and HPGe Detectors in the South Caspian Region
Natural radionuclides present in soil as well as certain anthropogenic radionuclides released to the environment are the major contributors to terrestrial outdoor exposures. In the assessment of human exposures from environmental radioactivity, besides the conventional method of soil and vegetation sampling combined with laboratory based analyses of environmental media, the other choice would b...
متن کاملEfficiency Loss in HPGe Detectors due to Beta and Gamma Sum Coincidence
Among the secondary detection effects in gamma-ray spectroscopy with HPGe detectors that reduce the peak area and must be properly taken into account in accurate measurements, the less well known is counting loss by beta and gamma-ray sum coincidence. The fraction of lost counts was estimated assuming that a photon detection event can sum either with the coincident beta-ray or its bremsstrahlun...
متن کاملA beta-ray spectrometer for coincidence measurements
An intermediate image beta-ray spectrometer has been constructed utilizing the focusing properties of a Ushaped magnetic field distribution. The construction and performance of the instrument are discussed. A transmission of ten percent has been attained with a resolution of about six percent. A scintillation spectrometer is used in conjunction with the intermediate image spectrometer for the p...
متن کاملGamma-gamma Coincidence Overlap Coincidence Method for Measuring Gamma-gamma Coincidence of Na Radiation Safety
RADIATION SAFETY The radioactive sources used in this experiment are only a few microcuries in strength, and they are all sealed, so they actually pose no significant health hazard. However we will follow good safety procedure. Horseplay involving the sources is forbidden. While the sources are not dangerous, like any radioactive source they should be treated with respect and properly handled. ...
متن کاملA coincidence scintillation spectrometer
The coincidence spectrometer consists of two scintillation spectrometers, each of which can be used as either a beta-ray or a gamma-ray spectrometer, depending on what crystals are used. The pulses from the first spectrometer are analyzed with a single channel analyzer. The pulses corresponding to a certain energy are picked out with the analyzer and are fed into one channel of a coincidence ci...
