I Live In An Apartment That May Have Lead Paint
Not at risk with this exposure only.
Detailed Answer:
Hello dear, welcome to Ask a doctor's service.
I read your query and here is my advice.
You should have used a wet mop to clean the dust in floor and a damped cloth to clean dust on other surfaces of furniture.
The drilling exposure only can not cause brain damage or sickness but a constant exposure to dust contaminated with lead - based paint may lead to lead-poisoning.
Brain damage is more common in children causing development delay , irritability, learning difficulties while adults as you may experience headache,high blood pressure, abdominal pain, mood disorders etc.
So as a conclusion you are not at risk of lead poisoning only by this exposure but you should avoid further exposure.
Hope I have answered the question.
Let me know if I can assist you further.
