We explore the screening of the scalar modes of polarisation of gravitational waves travelling across the evolving galaxies. This is done in the modified f(R) gravity background. The observation of such modes is found to be dominantly suppressed by a chameleon mechanism in the gas rich environment of the galaxies. We constrain the dark matter equivalence of the scalar mode contributions. The degree of suppression is also found to constrain the future observations which are dominated by tensor modes. It is proposed that the influence on the polarisation by the varying density galactic backgrounds serves as a new and strong approach to distinguish the CDM model from the alternative gravity theories. We compare our results with the current galactic observations.
