Magneto-transport measurements have been carried out to investigate the effect of 250 MeV Ag+17 ion irradiation on the flux pinning properties in YBa2Cu3O7-δ polycrystalline films. The ohmic resistivity measurements of the films above the Bose-glass temperature, TBG, have been carried out as a function of temperature, magnitude and orientation of the magnetic field with respect to the columnar defects. The experimental results have been analysed on the basis of Bose-glass theory. The angular dependence of resistance shows a dip and the Bose-glass temperature is found to be a maximum when the magnetic field is aligned with the columnar pins. Angular critical scaling laws have been used to determine the static ν' and dynamic z' exponents. In addition, the prediction of universal behaviour of Bose-glass theory below the critical angle has been observed.
