The OPA study puts the first question to rest.

"The RF exposure measurement survey detailed in the report found that the included Smart Meters and associated AMI infrastructure devices produced emissions significantly below the maximum power density exposure levels as outlined by the FCC in the OET Bulletin 65 Ed. 97‐01 for the general public.

In the extreme case the survey identified, the highest peak (short duration) percent of Maximum Permissible Exposure (MPE) was 13.4% of the FCC limit, measured near the Smart Meter at location M‐1 outside of the Smart Meter’s expected period of maximum activity. This reading likely included the RF signals from a number of possible nearby sources. The equivalent time‐averaged exposure level would have been 4.6% of the FCC exposure limit for the General Population.the CMP system broadcasts at a peak intensity that is less than 5% of the FCC standard."

The remaining question in the case goes to the adequacy of the FCC standard to protect public safety for any RF device; a broad policy question that CMP has argued falls outside of the Commission's expertise and authority to decide.
