Abstract

Radiation protection in mixed neutron/gamma fields produced by radiation sources is relevant in many industrial applications such as bore hole logging and prompt gamma neutron activation analysis, security applications and neutron radiography. Online monitoring of the dose equivalent received from a neutron/gamma source would permit real time dosemetry in industrial and medical applications. A silicon on insulator (SOI) microdosemeter has been used to determine the microdosemetric spectra from a source which can be converted to dose equivalent. Simulations of the response of a SOI microdosemeter to the source using GEANT4 have been performed.
