I'm not a particle physicist, but as I understand it, it wouldn't be very exciting to be hit by this because even if it interacted with you, the shower of particles produced would be so energetic that they'd nearly all come right out of the other side of you and go deep into the Earth before hitting anything else. One atom gets smashed, and one molecule gets excitingly altered but that's all in a day's work for biology. It's a bit like how the depth where the energy is deposited of radiotherapy gets deeper with increasing energy. Past a certain energy (hundreds of MeV), most of the energy ends up being delivered somewhere behind you. This particle is hundreds of billions times more energetic than that radiation.
