Scientific paper

We find some errors in previous calculation of leading log QCD corrections to $b \to s\gamma $ decay, which include corrections from $m_{top}$ to $M_W$ in addition to corrections from $M_{W}$ to $m_b$. The inclusive decay rate is found to be enhanced more than previous calculations. At $m_t=170$GeV, the running from $m_{top}$ to $M_W$ results in 13\% enhancement, and for $m_t=250$GeV, 16\% is found.
