My Landlord Started Scraping The Paint On The Siding Of

My landlord started scraping the paint on the siding of our house the other day and left paint chips all around the house which I tested this morning and they tested positive for lead. We have been walking in the area and tracking the chips inside as well at the dogs. I plan on calling my daughters doctor first thing in the morning since it is Sunday afternoon but should I be more concerned? Is that enough exposure to be considering bringing her to the hospital or am I just overreacting?
