We offer a shielding service for CRTs, where we certify emissions down to 0.1 milligauss.
Mu metal is 80% Nickel, 4% Molybdenum and 16% iron.  It looks like the bumper of a car.  It is frequently used in tape recorders, you see it when you look at the recording head, which is encased in a shiny metal (Mu metal), which prevents the electronic hum from the motor half an inch away from inducing a buzz on the recording.

The charge to shield a CRT is $ 295 + shipping of $ 24, for a total of $319.  Send the unit, insured, to our headquarters at:
