I don't know where these utterly ludicrous ideas originated!

To be at all effective you must use materials which provide magnetic
shielding. Non ferrous materials (here Aluminium (to be confused with
Aluminum)) do not, of course, work for this purpose. At the minimum one
should wear soft iron sheet headgear and preferably a mu-metal cap should be
employed - especially if near field radiation (in either direction) is of
concern. Recent private correspondence suggests that use of steel from
WW1-vintage German capital ships scuttled at Scapa Flow may be of additional
utility if low radiation count is an ancillary consideration. This material
is much used in space probes and the Aurora-brigade should probably ponder
possible correlations with the use of personal EM shielding headgear.
