In this paper, we prove that for $sin(1,2)$ there exists no totally lower irregular finite positive Borel measure $mu$ in $R^2$ withreak $mathcal H^s(suppmu)<+infty$ such that $|Rmu|ci{L^infty(m_2)}<+infty$, where $Rmu=muastfrac{x}{|x|^{s+1}}$ and $m_2$ is the Lebesgue measure in $R^2$. Combined with known results of Prat and Vihtil"a, this shows that for any non-integer $sin(0,2)$ and any finite positive Borel measure in $R^2$ with $mathcal H^s(suppmu)<+infty$, we have $|Rmu|ci{L^infty(m_2)}=infty$.
