Our (PanAm) GOM said to operate WX Radar to chase birds, and to turn off the radar when approaching terminal and facing people such as the agent marshalling the aircraft to the parking spot.

Remember one time, as F/O arriving in Calcutta, I forgot to turn-off the radar after landing. Oops... we bombarded the marshall with a lot of nasty rays from our antenna. Captain said "not to worry, we made the bloke unable to make babies, not a concern with the local population boom".

Apparently, radar renders males unable to procreate...???
Full blast in China and India with your radars...!
