Back in April we reported on the FCC’s most recent foray into the thorny issue of health effects of radio waves. The FCC adopted minor tweaks to its existing rules, proposed further tweaks, and sought comments on broader issues, including the controversial question of whether the current radio-frequency exposure limits are safe, and if not, what they should be.

The document has now been published in the Federal Register, in two separate parts. The first part sets out the newly adopted rules; the second part poses the questions on which the Commission has requested comment.

Publication in the Federal Register establishes both (a) the effective date of the rule changes that were adopted and (b) the deadlines for comments on the out-for-comment questions. The adopted changes will become effective on August 5, 2013. Comments will be due on September 3, 2013, and reply comments on November 1.
