How often should a leak test using an XRF be conducted?

Conducting a leak test using an X-ray fluorescence (XRF) device every 6 months is recommended because it ensures that the calibration and functionality of the device are maintained. Regular testing helps identify any potential leaks or issues that could compromise the accuracy of lead measurements. By performing the test biannually, practitioners can ensure that their equipment is reliable and their assessments are valid, contributing to the overall safety and effectiveness of lead risk assessments in various environments. This frequency aligns with established best practices in environmental monitoring and risk assessment, ensuring compliance with regulations and safeguarding public health.
