Deposited energy multiplied by factor C (Eqs. (2), (3) and (4)) takes in to account the fact that the phantoms have different masses and sizes. The analysis shown here is reduced to four GCR species: protons, and He, O and Fe nuclei. After the re-scaling, we can compare the relative differences in absorbed dose rate that the phantoms would suffer if they were placed in to the same radiation field. We see that the the relation between phantom size, shape and measured dose has a non trivial dependence on particle type and energy. The calculated data indicates that the smaller slab and sphere phantoms suffers a higher absorbed dose for most particle types and energies.
