Following a potential intake incident in a research facility, a health physicist must assess whether an employee inhaled alpha-emitting actinides (primarily 239Pu with some 241Am). Surface contamination surveys show 2,400 dpm/100 cm² on the worker's lab coat. Which monitoring approach would provide the MOST definitive assessment of internal contamination within the first 24 hours?
This is 10 of 150 blueprint-weighted questions. A team plan unlocks the full bank, mock exams, and per-member readiness tracking.
