Monte Carlo Simulation of Activity Measurements by Means of 4πβ-γ Coincidence System
Monte Carlo Simulation Activity Measurements 4πβ-γ Coincidence System
2010/10/25
The theoretical work is being developed with MCNP Monte Carlo code, applied to a gas-flow proportional counter of 4π geometry, coupled to a pair of NaI(Tl) crystals. The calculated efficiencies are co...
Compaction and Swelling of Ca-Smectite in Water and in CaCl2 Solutions: Water Activity Measurements and Matrix Resistance to Compaction
