MS-PC 2015: Performance Specifications for Instrumentation Systems Designed to Measure Radon Gas in Air Page 19 of 20 Relative Humidity Group (high) (Sec. 7.5) Requirements: Each IPE = 0 ± 25% and COV ≤ 15% for each set of five devices. Temperature _______ range 18 – 24°C (65 – 75°F) Rn Conc __________ > 370 Bq/m 3 (10 pCi/L) RH______ range 70 – 80% Serial number Date-time start Date-time end Temp RH Device result STAR conc IPE COV Minimum Detectable Concentration (Sec. 7.2) Requirement: ≤ 37 Bq/m 3 (1 pCi/L) for measurements of 2 days or longer; for 1-hour measurements, the MDC shall be no greater than 148 Bq/m 3 (4 pCi/L). Tests to determine MDC are run outside the STAR(s); and the individual device results, including exposure durations and the complete calculations, are provided in this report. Calculations are performed using the algorithms in Section 4. The MDC is: _____________ (units) for the measurement duration of ______________.
