Title: Development of method and system for generating low-energy neutrino in high-voltage gauge field
Inventor: YAMASHITA ETSUKAZU
IPC: A61N5/10
Filed: 2003-02-14
Abstract: <P>PROBLEM TO BE SOLVED: To provide a radiation therapy which does not give damage to normal cells.  <P>SOLUTION: As a candidate of radiation not causing ionization over a wide region in the living body, electron neutrino was adopted. Though neutrino is considered to be concerned with β-decay as it has a weak interaction, it is thought to have no effect on other organs even if β-decay reaction occurs in tumor tissues as the reaction is very local. As a method for generating neutrino under low energy, neutrino is generated by using an upper hexagonal structure (anode) and lower hexagonal structure cylinder (cathode) in a low-energy region of about 30kV.  <P>COPYRIGHT: (C)2004,JPO&NCIPI
