The flux of neutrinos through the Earth is such that about 10¹1 pass through the area of a fingernail each second, but in your lifetime only one is expected to interact with your body. From this, estimate the mean-free path of the neutrinos in your body and make an estimate of the average cross section for interaction with a nucleon (assume either nucleon can interact equally).

Nuclear interactions

In nature, there are certain rules and standards for an interaction. These interactions are universally accepted. There are four types of interactions:
