Where can I find reliable EMF shields?

I'm sensitive to electromagnetic fields from my computer monitor, and I strongly suspect it's responsible for my stomach stabbingness and urinary tract infections. It also causes me migraines (as do fluorescent lighting in shopping centers).

It's probably related to my dental mercury toxicity (see this: http://jadespring.home.att.net/field.htm

Anyway, where can I find trustworthy EMF shields? I prefer personal testimonials from someone who actually is using such a shield and knows it works (perhaps by testing it via a meter?

P.S. Why don't they make mandatory that sellers of monitors must also provide reliable shielding for the sake of sensitive people? Tweet
