One way to quantify RF exposure is with a tool published by VK3UM mostly
for the EME community where radio power levels are higher than what is used
for low earth orbit satellites:

I bought a camera tripod at a hamfest for 10 bucks. Then, I made a pad
the size of a camera attachment and bolted it to my Arrow. It slips right
in/out quickly/easily. I also found an exercise weight to balance the
Arrow when attached to the tripod and it is permanently mounted at the
end of the antenna. All of the elements are in front of the mounting. This
arrangement gives me full AZ/EL and polarity capability that is
constantly adjustable during a SAT pass and doesn't require me to have
a third hand for controlling every other thing that takes place during
a Rover operation. Logging is done with a small digital recorder and
its mic is shoved into my left headphone ear-cup and both sides of
of the QSO are recorded for later transcription. One hand holds the
mic for PTT and the other hand tunes the XCVR. It has all worked
FB for the past 7 years and 98 Rover Grids. And, if it's windy, I have
a plastic gallon jug of water I hang on a hook from the bottom of the
tripod to keep it from blowing over (again)! - Bob K8BL

I use a good camera tripod with the setup I made. Since I also do
photography it was on hand. If you get a cheap camera tripod, I am sure
you will have issues of some sort. A good heavier tripod is great, it
will keep from tipping over. You can see my arrow antenna rig on tripod
on my QRZ page.

Personally, I'd worry more about processed meat and bacon consumption,
smoking, alcohol intake, sun exposure, and pollution before I'd be concerned
about a few watts of UHF/VHF.
It would, of course, be unwise to stare into a 23 element 70cm beam driven

Zach,
Interesting that you mention high power RF safety. The FCC will
require all hams to submit an RF safety certification with license
renewals. Hams will need to submit documentation supporting the
safety of their stations and possibly keep field strength monitoring
equipment at the QTH.
The strictest limits will be placed in 50 MHz to 500 MHz range since
the human body absorbs RFI energy efficiently in this frequency range.
This should affect small satellite stations but will affect EME class
station nestled in neighborhoods.

Paul,
I suspect you meant "should not" in that last sentence.
For those of you not familiar with these regulations:
http://www.arrl.org/fcc-rf-exposure-regulations-the-station-evaluation
At 70cm, stations are assumed, by the FCC, to be meeting the exposure
guidelines with up to 70 watts of power input to the antenna. There is
no language about EIRP, which, strangely, is what really matters.
I'd much rather stand next to a horizontal dipole radiating 1.5kW than
be in the boresight of an EME array at 70W.
An interesting NIH paper which summarizes the effects of RF exposure:
https://www.ncbi.nlm.nih.gov/books/NBK208983/
I think I'll stick to limiting my extra-crispy bacon intake to the
weekends. ;-)

It's not because it doesn't exist and never will unless the FCC

Subject: [amsat-bb] Upcoming ARISS contact with Fleet Science Center,
BE WISE Program in San Diego, CA

An International Space Station school contact has been planned with
participants at Fleet Science Center, BE WISE Program in San Diego, CA, on
19 Aug. The event is scheduled to begin at approximately 16:44 UTC. The
duration of the contact is approximately 9 minutes and 30 seconds. The
contact will be direct between NA1SS and KJ6KDZ. The contact should be
audible over the state of California and adjacent areas. Interested parties
are invited to listen in on the 145.80 MHz downlink. The contact is expected
to be conducted in English.
The Fleet Science Center connects people of all ages to the possibilities
and power of science to create a better future. Established in 1973, it was
the first science museum to combine interactive science exhibits with a
planetarium and an IMAX Dome (OMNIMAX) theater, setting the standard that
most major science museums follow today. The Fleet is home to many programs
that engage girls in science, one of them is BE WiSE (Better Education for
Women in Science and Engineering). BE WiSE BE WiSE engages young women in
science, technology, engineering and math (STEM) learning experiences in
collaboration with the region's research, industry and academic
institutions. BE WiSE goals are to: stimulate young women's interest in STEM
through interactions with professionals, increase participants'
opportunities and knowledge of STEM fields of study, develop a community of
young women (grades 7-12) engaged in science learning through out-of-school
activities, and sustain interest and involvemen
t through alumnae and ongoing participation for women in science at all
levels. BE WiSE selects girls from all across San Diego County and has
sustained contact with over five hundred girls over the past 14 years.
Participants will ask as many of the following questions as time allows:
1. How does being on board the ISS for long periods of time affect your
overall health?
2. When deciding to be an astronaut, did you have any doubts? If so, how did
you overcome them?
3. What is the most interesting experiment you are doing on the ISS right
now?
4. Have you ever dealt with malfunctions on board the ISS? If so, how did you
solve it?
5. What do you like most about the ISS?
6. Is it hard to sleep? What do you dream about?
7. If you get sick on the ISS how do you receive treatment?
8. What does weightlessness feel like?
9. What is a typical day like for you?
10. Do you miss "real" food? What kinds of food do you like on the ISS?
11. Do you get heartburn/acid reflux? How do you deal with that?
12. What is the most interesting thing you have seen aboard the ISS?
13. How much does microgravity affect the experiments that you conduct on the
ISS?
14. What does the orbital sunrise look like?
15. What kind of medical testing do you go through before/after being in
space?
16. Are they currently working on lighter, more flexible space suits?
17. Do scientists from different countries collaborate on projects? If so,
what kind?
18. How much time do you spend practicing in zero gravity before going into
space?
19. How do you think private space travel will affect the ISS?

About ARISS:
Amateur Radio on the International Space Station (ARISS) is a cooperative
venture of international amateur radio societies and the space agencies that
support the International Space Station (ISS). In the United States,
sponsors are the Radio Amateur Satellite Corporation (AMSAT), the American
Radio Relay League (ARRL), the Center for the Advancement of Science in
Space (CASIS) and National Aeronautics and Space Administration (NASA).
The primary goal of ARISS is to promote exploration of science, technology,
engineering, and mathematics (STEM) topics by organizing scheduled contacts
via amateur radio between crew members aboard the ISS and students in
classrooms or informal education venues. With the help of experienced
amateur radio volunteers, ISS crews speak directly with large audiences in a
variety of public forums. Before and during these radio contacts, students,
teachers, parents, and communities learn about space, space technologies,
and amateur radio. For more informa
tion, see www.ariss.org, www.amsat.org, and www.arrl.org.
Thank you & 73,
