QA/QC - Short Term Radon Tests have an estimated margin of error of ±5% when used according to directions.

Please see page 3 of the report for a list of personnel.

Measurement Specialist / Laboratory Director Date 1/25/2024

Quality Assurance (QA): Sample Type: Short Term. Technology: Activated Charcoal. Device Manufacturer: Alpha Energy Laboratories. Model: RD-1. NRPP Approved Device: AC-8202.

Device Performance Standard: ANSI-AARST MS-PC 2022. Quality Assurance Standard: ANSI-AARST MS-QA 2019. Lab Methodology: EPA-402-R-92-004. Test instructions designed in accordance with ANSI-AARST MAH-2019. Radon level uncertainty is calculated using a 95% confidence level. One sampler can test up to 2,000 ft2.

Disclaimer: Results are only indicative of the sample as received in the lab. Incorrect information or improper sampling procedures will affect results. Alpha Energy Laboratories (AEL) did not provide sampling services unless otherwise indicated. Device deployment/retrieval is assumed to be performed by the person submitting the sample, unless otherwise specified by the client. The person(s) performing sampling are responsible for sampling QA, which may include duplicate, blank, and/or spiked detectors. Analysis, laboratory QA, and production QA performed by AEL. Measurements are not necessarily predictive or supportive of measurements conducted at different times or locations. AEL is not responsible for the consequences of any action you do or do not take based on the results. This report may only be reproduced in full, unless authorized in writing by AEL.

RADON RESULTS SUMMARY

This page includes a summary and basic statistics. Quality Assurance (QA) tests are generally recommended but not always required. When required, Blanks should be placed at a rate of 5% of all testing locations and Duplicates should be placed at a rate of 10% of all testing locations. Spikes may be required for some projects.

Quality Assurance

Note: Additional QA tests may have been performed on a blind basis (not reported to the laboratory as QA tests). This report only considers tests reported to the lab as QA tests.

Summary of Measurement Results A total of 9 radon detectors were deployed during the testing period. To ensure accuracy, Quality Assurance tests were performed, including 1 duplicate detector(s) (placed side-by-side for intercomparison). Results ranged from the lowest reading of 1.4 pCi/L to the highest reading of

12.4 pCi/L.
