They would be confused, but your also dealing with animals that eat nukes. They don't really have threats when they become adults so panic isn't going to be their reaction they certainly wouldn't be calm but they would be more concerned with finding one another than smashing stuff for no reason. Even when they were attacking humans in the movies it was more akin to swatting an annoying bug than true malicious intent. After finding one another they'd investigate the area a bit, upon finding that there isn't enough radioactive materials for them to feed on let alone breed with (as was their goal in the movie) they'd probably move on in search of their highly specialized food source. They'd probably keep wandering around until they found a uranium deposit or something then settle there to nest. Granted anything that happend to be in there path would end up like an ant hill in the way of an elephant but their behavior wouldn't be much of an actual rampage.
