What makes you think understanding of radiation is necessary to dig? Even if they had that understanding, why would they bother using a geiger counter on an archaeological dig? And plants can adapt - chernobyl is quite hazardous, but plant life still grows there, and there's no guarentee that any effects on their growth will be understood (and any level of radiation enough to _really_ effect them will effect people standing on the surface too)
