Copper shielding probably is the best. I have some extra copper, would you suggest to make such a shield?
Wiki - RF shielding enclosures filter a range of frequencies for specific conditions. Copper is used for radio frequency (RF) shielding <https://en.wikipedia.org/wiki/Copper_in_architecture#Radio_frequency_shielding> because it absorbs radio <https://en.wikipedia.org/wiki/Radio_wave> and magnetic waves <https://en.wikipedia.org/wiki/Magnetic_wave>. Properly designed and constructed copper RF shielding <https://en.wikipedia.org/wiki/Copper_in_architecture#Radio_frequency_shielding> enclosures satisfy most RF shielding needs.
