(1) Attenuation is estimated using a theoretical formula as the ratio of measured field before shielding to that measured after shielding. Typically, attenuation decreases in shields of larger volume, thus thicker layers of MuMETAL® are required. Attenuation ratios above are estimated at room temperature in an Earth field of 0.5 Gauss – actual results will vary in different operating environments.
