Do these reduce emf radiation or only emi? would like to put on monitor and computer adapater to reduce rf radiation.

I use these torroids on every wire connected to my ham radio to prevent spurrerus RFI interfering with the signal.

Are there any data sheets for these cores? I'd like to kniow the specs on these.

As I have recently found out through my mentors that the ferrite composite is not known and it appears it's not always the same during their continual manufacturing process over time. They have recommended and I would agree to go to a place like Palomar where you know exactly which ferrite material you're getting for your frequency needs

If I put one of these on every lead to appliances that makes a spark (mixer, crock pot thermostat) will it stop my Arc fault breakers from tripping?

No it will not. if you are having arc fault breakers tripping you have a problem that should be looked into by a liscensed electrician. more than likely there are loose connections in your recepticles or it could be your appliances. arc faults in your recepticles will get worse with time and could cause damage or even set your house on fire.
