radiotelescope and sterility...
 

Hi,

We know that during the emission of a radiotelescope (rare, for tests or to
send SETI msg, Hi!), the radiation can sterilize people working in the dish.
Has someone some idea of the power require to produce such a effect or any
generic graph (from IEEE standards ?) showing the risk vs frequency or
emitting power ? I have one,
http://www.astrosurf.com/lombry/Radi...ower-field.gif but I would like
to get a better idea of the power require (in W, Jy, etc).
If I had an idea of the require dBi and W , I could compute the EIRP and all
concerned values.

Thanks in advance

Health Canada's Safety Code 6.

Hint - it's not a dish issue with huge dishes. It might be a feed issue
in the worst case. The bigger the dish, the less the issue (the feed
being further away).

Likely, the 600mW cell phone is worse. And the 5w hand held W/T is
even worse than that.

If you own a strong magnet and an electric stove, hold the magnet in
your hand and turn on one stove top electric burner element to max.
Bring the magnet close to the element and feel the very strong
vibrations. (Don't burn your hand.)

Nonsense - we know nothing of the sort.

If "We" know all this, "We" should not be in the dish when these test
are being conducted. Duhhhh.....

No-nonsense, it is sense. RF exposure causes temporary sterility, kinda birth
control. Too much RF can cook us.

A radio telescope is a receive-only device. It is incapable of rendering
anything sterile.

A radar telescope--using a dish--can be dangerous and the EIRP can be
megawatts. In this case, a number of health dangers apply. Fortunately those
most likely to be exposed are the best informed, and I am not familiar with a
single case of dangerous exposure.

SETI has nothing to do with this.

Depends on the fequency.
The fact that you're still here confirms it's not too bad.

We recommend getting a vasectomy instead of microwaving yourself. Its less
painful, and cleaner.

According to a article I read sometime ago the people that built the
BWMEWS system in Greenland used to stand in front of the antenna and
warm up.

I wouldn't depend on it, Yuri. You'd have better luck with the
rhythm method.
