Comparative measurements in dose calibrators and a gamma-ray spectrometer.
Specific activity results of (51)Cr, (67)Ga, (99m)Tc and (201)Tl radioactive solutions, measured in different dose calibrators located at nuclear medicine services and in a calibrated HPGe gamma spectrometer, were compared. The HPGe spectrometer was calibrated in a well defined geometry by means of (60)Co, (133)Ba, (152)Eu, (166m)Ho and (241)Am sources, previously standardized in a 4pibeta-gamm...
متن کاملProducing 65Zn and 60Co gamma sources for energy and efficiency calibration of gamma spectrometry systems
Precise calibration of energy and efficiency of gamma spectrometry systems for different geometries is very important. In most cases, preparation of these sources for educational and research centers is very difficult due to high costs and lack of access to the reactor. The purpose of this paper is to explain the procedure for production of calibration sources 65Zn and 60Co using instrumental ...
متن کاملTransient Gamma-Ray Spectrometer
Visible afterglow counterparts have now been detected for two GRBs (970228 and 970508) but are absent, with Lopt/Lγ ratios at least two orders of magnitude lower, for other GRBs, e.g., 970828. The causes of this variation are unknown. Any correspondence which could be discovered between the γ-ray properties of a GRB and its Lopt/Lγ would be useful, both in determining the GRB mechanisms, and in...
متن کاملThe NEAR X-Ray/Gamma-Ray Spectrometer
he X-Ray/Gamma-Ray Spectrometer on the Near Earth Asteroid Rendezvous (NEAR) spacecraft will remotely sense X-ray and gamma-ray emissions from the surface of near-Earth asteroid 433 Eros and look for characteristic “signatures” in those emissions to determine its elemental composition. During the planned 10 months of orbits about Eros beginning in early 1999, data returned from the instrument w...
متن کاملCdZnTe Gamma Ray Spectrometer for Orbital Gamma Ray Spectroscopy
We present the design and analysis of a new gamma ray spectrometer for planetary science that uses an array of CdZnTe detectors to achieve the detection efficiency needed for orbital measurements. The use of CdZnTe will provide significantly improved pulse height resolution relative to scintillation-based detectors, with commensurate improvement in the accuracy of elemental abundances determine...
