This subject deals with foundational knowledge for all students in NED.
Emphasis is on nuclear concepts (as opposed to traditional nuclear physics), especially nuclear radiations and their interactions with matter. We will study different types of reactions, single-collision phenomena (cross sections) and leave the effects of many collisions to later subjects (22.105 and 22.106). Quantum mechanics is used at a lower level than in 22.51 and 22.106.
