The document describes analyzing data from a Raspberry Pi-based cosmic radiation detection system to test sensor performance and track radiation sources. It discusses running tests to analyze the influence of a radiation source on hit rates over time, measure proximity sensitivity by varying a source's distance, and track a moving radiation source. The goal is to evaluate the system's effectiveness in detecting and locating radioactive materials for applications like homeland security and cargo scanning.
