Epithermal Neutron Beam Generator Design for Bnct
BNCT is a radiotherapy modality based on the neutron capture and fission reactions that occur when boron-10 is irradiated by thermal neutrons. This reaction generates alpha and lithium that produce high density of ionizations in close to the reaction site. The concept provides high absorbed doses into the cancerous cells preserving the adjacent healthy tissues. Nowadays, the available neutron s...
متن کاملLate Cretaceous Volcanoplutonic Arcs in Northwestern British Columbia: Implications for Porphyry and Epithermal Deposits
Porphyry Cu and epithermal deposits are spatially and temporally related to specific volcanic and plutonic rocks emplaced during the formation of long-lived magmatic arcs formed along convergent plate boundaries (e.g., Sillitoe, 1972; Sutherland Brown, 1976; Titley, 1982; Sawkins, 1990; Bissig et al., 2003). Recognizing the presence, types of deposits, and age of the mineralized volcanoplutonic...
متن کاملLandsat ETM+ Imaging for the Exploration of Epithermal Deposits in the Azuero Peninsula (Panama)
Remote sensing can be understood as the science, technology and art of acquiring, processing, and interpreting airborne or spaceborne images that record the interaction between matter and electromagnetic energy (Sabins, 1997, Aranoff, 2005). Nowadays a plethora of satellites surrounding the earth provides continuous sets of data of quite different nature used for navigation, positioning, meteor...
متن کاملgeochemistry of hydrothermal alterations associated with epithermal gold mineralization in masjeddaghi area, east of jolfa, nw iran
two types of mineralization including porphyry copper and epithermal gold mineralization have occurred in relation with an intermediate volcano-plutonic complex in masjeddaghi area. different alterations including silica, advanced argillic, intermediate argillic and propylitic have been distinguished in relation with epithermal mineralization, which have a zonal pattern. elemental mass gains an...
متن کاملAccelerator based epithermal neutron source for NCT
Nowadays neutron capture therapy looks very promising method of cancer treatment, especially for brain tumors by reason of selective damage cancer cells. Treatment effect of this method based on neutrons nuclear reaction with nuclides B, Gd. These nuclides have high cross-section of interaction with thermal neutrons. Unfortunately, thermal neutrons could enter only in near surface tissue and co...
