In this paper we prove that, given s> 0, if E is a subset of Rm with positive and bounded s-dimensional Hausdorff measure Hs and the principal values of the s-dimensional signed Riesz transform of Hs|E exist Hs-almost everywhere in E, then s is integer. Other more general variants of this result are also proven.
