It's possible the noise quite soon after the door is opened is still below the
limit for unintentional or incidental emitters. That's enough to interfere with
radiotelescopes.

IEC/EN 60335-2-25 and IEC/EN 60335-2-90 have limits on the radiation emitted
from the microwave with the door open. This includes testing with the seal
broken and the door closed, when possible. The limits are pretty strict so I
would be a little surprised by this. I haven’t read the article, nor do I
know the history of the standard so there maybe something there too.

My question is this. If the RF generated inside the oven does not stop
prior to the opening of the RF seal on the door, which testing is
responsible to identify this problem, EMC or the Safety testing
Not 'either/or': emission with the door open violates CISPR 11/EN 55011, it's
also a violation of the Section of IEC/EN 60335-2 (too late here to look it
up) and potentially a violation of the regulatory EMF exposure limits as
measured according to IEC 62233.
