Measuring γ–ray dose of terrestrial samples using β-γ Spectrometry
Background: The existence of some radionuclides in soil and some building materials produce a β-γ radiation field, which in some regions the exposure of these radionuclides to human is high. Materials and Methods: The air-absorbed dose, indoor and outdoor annual effective dose of soil and some building material samples (ceramic, granite, gypsum, etc.). The samples were collected from 3...
متن کاملγ - γ Coincidence in 22
Na radioactively decays to an excited state of Ne either by emission of a positron (90% probability) or by electron capture (10% probability). The excited Ne nucleus decays with a mean life 3×10−12 s to the ground state with the emission of a 1.274 MeV gamma. The positrons are emitted with a range of kinetic energies up to about 0.5 MeV. They lose this energy quickly (10−9 s) in the material !"...
متن کاملHigh resolution mass spectrometry.
Over the past decade, mass spectrometry has been revolutionized by access to instruments of increasingly high mass-resolving power. For small molecules up to approximately 400 Da (e.g., drugs, metabolites, and various natural organic mixtures ranging from foods to petroleum), it is possible to determine elemental compositions (C(c)H(h)N(n)O(o)S(s)P(p)...) of thousands of chemical components sim...

متن کاملAutomatic and Interactive Analysis Software for Beta- Gamma Coincidence Systems Used in Ctbt Monitoring
A suite of software has been developed by Veridian Systems as part of the Prototype International Data Center (PIDC) to assist in the analysis of noble gas monitoring data for the Comprehensive Nuclear-TestBan Treaty (CTBT). There are two acceptable noble gas monitoring methods for CTBT verification purposes: high-resolution gamma-ray ( ) spectrometry and beta-gamma ( ) coincidence. Data from s...
