Neutron Capture Gamma Rays ( Thermal Neutron
Detection of landmines using nuclear techniques has been studied extensively since the late 1940s. Nuclear techniques look at either a return radiation, which is characteristic of explosive components that are infrequently found in soil (e.g., nitrogen or carbon), or an intensity change of a noncharacteristic scattered radiation, which is a function of a parameter that differs between soil and ...
متن کاملGamma Ray Interaction and "Neutron Capture Gamma Ray Technique for the Analysis of Cu-Ni Alloys"
The neutron capture gamma-ray technique was used for the analysis of Cu-Ni alloys, widely used in industry. The two elements, which are very close in atomic number, have widely separated characteristic capture gamma quanta. A sensitivity of 7x10 counts per unit thermal neutron flounce per 1% change in Ni/Cu ratio was obtained. Samples of any shape can be analyzed without a need for any special ...
متن کاملAre gadolinium contrast agents suitable for gadolinium neutron capture therapy?
OBJECTIVE Gadolinium neutron capture therapy (GdNCT) is a potential treatment for malignant tumors based on two steps: (1) injection of a tumor-specific (157)Gd compound; (2) tumor irradiation with thermal neutrons. The GdNC reaction can induce cell death provided that Gd is proximate to DNA. Here, we studied the nuclear uptake of Gd by glioblastoma (GBM) tumor cells after treatment with two Gd...
متن کاملGadolinium in human glioblastoma cells for gadolinium neutron capture therapy.
157Gd is a potential agent for neutron capture cancer therapy (GdNCT). We directly observed the microdistribution of Gd in cultured human glioblastoma cells exposed to Gd-diethylenetriaminepentaacetic acid (Gd-DTPA). We demonstrated, with three independent techniques, that Gd-DTPA penetrates the plasma membrane, and we observed no deleterious effect on cell survival. A systematic microchemical ...
متن کاملInvestigation the Effects of Neutron Source Number and Arrangement in Landmines Detection by Thermal Neutron Capture Gamma Ray Analysis
Thermal neutron capture can be used as a successful technique for detection of non-metallic landmines via the detection of their constituent like nitrogen. Recently, it has been shown that the detection of 10.829 MeV photons from the N(n,γ)N reaction can be used for finding the landmines. In this method a high-energy neutron source like Am-Be inside water as a moderator is used to have thermal ...
