March 29, 2013 .Today, the FCC —finally— issued a package of rules and information requests related to RF health and safety. We say finally because the commission announced that this was on its way last June (see "What's Up at the FCC?"). No one at the FCC is eager to say why it took so long, except that it covers a lot of ground. The document is indeed long (over 200 pages) and complex. There are some new final rules; for instance, the pinna is now officially an "extremity" and subject to a much looser SAR limit (see ¶42). And, there are some new proposed rules; for instance, a blanket exemption for all transmitters with a power output of 1 mW or less (see ¶121). But none of these is a major change. The heart of the document is a Notice of Inquiry (NOI) to help the FCC determine whether it should reassess its RF exposure limits. This is just about what the GAO recommended last summer that the FCC do with respect to cell phones. From Microwave News
