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.

Yes it does.
My post states in the case of the RT is used (was sued) to send SETI msg,
like to Arecibo and others.
Please believe, I know what I say.
