Home investigations are done by trained people who try to locate sources of lead in the home, buildings, or other structures. The state health department conducts investigations when a child has a confirmed blood lead level of >= 10 ug/dL. Otherwise, if you want your home tested, contact a lead inspector or lead risk assessor.
When a home investigation is done, the hand held XRF machine is used to locate lead sources in the home. The machine uses X-ray technology and must be used with care to prevent exposure to harmful radiation. This is why investigators are always trained professionals. Sometimes dust and paint chip samples are collected and sent to a lab for testing. When the results come back, the investigator gives the homeowner a detailed report of the findings. Recommendations are also given on ways to get rid of the lead hazard.
