Radiation Survey System for Effective Dose Rate Determination

The radiation field is segmented into multiple discrete locations around the detector, with radiation spectral data acquired at each location independently. This segmentation allows the system to determine the directionality of radiation sources by comparing spectra from different spatial positions, ultimately enabling accurate effective dose calculation without requiring complex directional sensing hardware at each point.

The patent transitions from single-point measurement to multi-location measurement by adding spatial dimensionality. Radiation spectral data is collected at multiple locations surrounding the detector, and this spatial information is used to determine dominant radiation travel paths and source directions, converting a one-dimensional measurement problem into a three-dimensional analysis that resolves the accuracy-complexity contradiction.

The system performs preliminary action by acquiring radiation spectral data at multiple locations and storing it for later analysis. Rather than determining directions in real-time during a single pass, the patent collects all necessary spectral data first, then processes it to identify dominant radiation travel paths and source directions, reducing the time penalty of multiple measurements.

The patent creates copies of the radiation spectral data from multiple locations and uses these copies to determine dominant radiation directions through comparison and analysis. Instead of requiring simultaneous real-time processing, the system captures spectral copies at different positions and processes them to extract directional information, minimizing time loss.
