A design for three-dimensional visualized detector of space's nuclear radioactivity

Based on the Geiger tube, we designed a miniaturized detector of radioactivity with three-dimensional visualization and corresponding software. We can capture clear distribution pictures of nuclear radioactivity on the detector's screen. In this work, a mathematical model for calculating the distribution was also developed which makes the three-dimensional nuclear radioactivity distribution from our detector more realistic and visible than the result from traditional point-like detection.
