System and Method for Acquiring Radiation Spectral Data in a Radiation Field and Determining Effective Dose Rate and Identifying Sources of Localized Radiation

A survey method and system for survey method and system for detecting and/or characterizing a radiation field The method may include acquiring energy-dependent radiation spectral data at a location of interest in a radiation field using a detector, wherein the energy-dependent radiation spectral data may include counts versus energy. The method may further include acquiring radiation spectral data at at least one other location wherein the at least one other location is positioned relative to the location of interest.
