A physics student needs to design and build a radiation detector to determine the type and intensity of the nuclear radiation emitted by a given source. The detector must be able to differentiate between alpha, beta, and gamma particles and provide accurate measurements of their energies. The student must also compare the performance of their detector with existing commercial detectors and suggest improvements.
