dc.description.abstract	The ratio of branching ratios of the radiative B decays Bd→K∗0γ and Bs→ϕγ has been measured using 340.1~pb−1 of \emph{pp} collisions at a centre of mass energy of s√=7~TeV taken with the LHCb detector. The obtained value for the ratio is 1.52±0.14(stat)±0.10(syst)±0.12(fs/fd). Using the HFAG value for B(Bd→K∗0γ), B(Bs→ϕγ) has been found to be (2.8±0.5)×10−5.	eng
