I use a cell phone as little as possible. Not sure there really is any risk
to it, but I just don't know. The damn things barely work, anyway, the
sound quality is awful and the mike and speaker are so close together you
can either hear, or be heard, but not both at once.
 
But, compared to a cell phone, or the now-ubiquitous cell towers, and other
transmitters all over, the electric meters are REALLY a minimal
contribution.

Well, if you feel strongly enough about it, the only option is have the
electrc service taken out!
 
I think you are going WAY overboard with this "irradiate me" statement.
These meters are such a small source of RF, and quite intermittent too.
Do you have the right to shut off all cell towers when you happen to be near
them? How about broadcast radio and TV? How about various radars operating
all over? You may not be aware of how MUCH electromagnetic radiation there
is going on from all these sources, but there really is a lot.
 
Oh, you know those things near the doors of most retail shops that have
something to do with deterring ahoplifting? Are you aware these are also
radio transmitters that interrogate anti-theft devices in many of the
products you buy at the local store? Do the stores even bother to tell
anybody what those devices are? You bet they don't tell you!
 
What I'm trying to point out here is that these meters that you are so
concerned about are tiny, compared to the huge "irradiation" you are
recieving all day, from a bunch of other sources that you may be totally
unaware of.

becomes reality. Then what will people do?? ;)

It is very easy to prove that something is unsafe. All you need is
one "victim" and an attorney. Once established, there will soon be an
infinite supply of victims, all with their palms raised, demanding
their fair share of the proceeds.
 
It is impossible to prove that something is safe, because there will
always be contrived circumstances where it can be made to be unsafe.
For example, water is unsafe because at some levels of consumption,
you become water intoxicated or will drown. Perfectly safe devices
can also be made unsafe by doing something stupid with them, such as
ingesting the article.
 
For RF exposure, the problem is compounded by the wide variety of
symptoms allegedly caused by RF exposure ranging from constipation to
cancer. Google for "electro sensitive". RF is mostly a problem
because we can't see or smell it thus making exposure seem all the
more insidious.
 
For smart meters (and wi-fi), the magic buzzword is "electro smog".
Lots of alarmist studies and reports available such as:
<http://www.nbcnews.com/id/34509513/ns/health-cancer/t/electrosmog-harming-our-health/>
I'm only familiar with the cancer research, about which I wrote this
rant and an associated informal talk:

A bit more up to date graph:

Details (later) if you want them.
 
I could probably answer your RF related questions, but so can your
local electric utility. Many have web pages on the topic of smart
meters. A few have real people you can call or write to get
information. Try those first, as it would take many pages of writing
for me to produce a personalized answer. If you don't get results,
bug me (later) and I'll try to fill in the gaps. For northern
California:

In California, the Public Utilities Commission has established rules for
those wishing to opt out of "Smart Meters" and stay with analog meters.
A one time $75 charge and then $10/month for 3 years. After
that there's no extra charge. (The $75 +$10/month covers both the
wireless electric and natural gas meters - you don't pay $150 + 20/mo
if you have both.) The charge is meant to cover the added cost of
someone coming to your residence every other month to read the meters.

It's a specific case of a very general problem, namely how to estimate
and control systematic errors in a measurement. Generally speaking, if
your hydrogen maser and your neighbour's caesium clock and your Russian
brother-in-law's Bose-Einstein condensation agree, you can be pretty
confident. Otherwise it's a real headache.

They don't call it "Coordinated Universal Time" (UTC) for nothing.
 
My wife is a manager at Australia's National Measurement Institute,
and works directly with the local "Time Lord" who's ultimately
responsible for one of the six atomic clocks that are used to determine
UTC. He's a nice bloke, too.
 
Of course, nothing in this would allow us to detect a systematic
slow-down in time itself, but if the effect was undetectable, how would
it matter? As long as everything slowed down at the same rate, it would
cause no effect that we could measure. So we compare the six clocks as
they wander around each other, and we try to pick a mean line between
them and call that line "coordinated time". And of course we do research
to try to find a way to build a clock which tracks that mean line better
than current ones do, which is how we got to where we are.

Clifford Heath: The biggest variant here is the planet
itself. Earth is slowing down, overall, at a more rapid
rate than any of the world's atomic clocks are speeding
up or slowing down. It's why an "ephemeris" second is
inserted every so many years.
