Here's the context of the EMF study:
On behalf of the California Public Utilities Commission (CPUC), three scientists who work for the California Department of Health Services (DHS) were asked to review the studies about possible health problems from electric and magnetic fields (EMFs) from power lines, wiring in buildings, some jobs, and appliances. The CPUC request for review did not include radio frequency EMFs from cell phones and radio towers. ... All three have published original research in the EMF area and have followed the field for many years.Here's the part that interested me from the executive summary. You can see that in general, Reviewer 1 thinks there is more risk than the other reviewers.
If you like that, you might want to "cook like an engineer". Alas, not everyone loves Tufte, in fact this person thinks he sounds like Gene Simmons from KISS :)
