Performing Tests & Device Placement

MAH-2023 placement rules (3 ft from exterior doors and windows, 1 ft from exterior walls, at least 20 in above the floor, 4 in object clearance), closed-building conditions 12 hours before tests under 4 days, 48-hour minimum duration, duplicate co-location, and tamper deterrence

Measurement Data Validation

Selecting charcoal, electret, alpha track, and continuous monitor devices; assessing CRM hourly data for diurnal patterns versus interference; RPD, equilibrium ratio, and pCi/L-Bq/m3 conversions; decay corrections; and interpreting recorded site data

Reporting, Records & Recommendations

MAH-2023 professional report contents (locations, device IDs, start/stop times, results, conditions, deviations), site-factor disclosure, chain of custody, non-interference agreements, post-mitigation verification timing (24 hours to 30 days), and retest-every-2-years guidance

QA/QC Program & Professional Oversight

MS-QA-2023 QA plan elements (SOPs, training, calibration, control charts, corrective action), duplicate (10%), blank (5%), and spike (3%) rates, annual CRM calibration, ethics and conflict-of-interest disclosure, scope of practice, worker exposure in working level months, and RMFT supervision
