KCI Job # 12146341.20
Location:
Walter Johnson High School
6400 Rock Spring Drive
Bethesda, MD 20814
Dear Mr. Cox:
KCI Technologies, Inc. (KCI) is pleased to submit the following report to the Montgomery County Public
Schools (MCPS) pursuant to completing a “short-term” 3 day radon test for the Walter Johnson High
School, located at 6400 Rock Spring Drive in Bethesda, Maryland 20814 (subject site).
Scope of Services:
KCI conducted radon testing at the subject site to evaluate indoor radon levels relative to the USEPA's
recommended action level of 4.0 picocuries per Liter (pCi/L) - the level at which EPA recommends that
schools take action to reduce the level. KCI conducted the radon testing in accordance with American
Association of Radon Scientists and Technologists (AARST) Protocol for Conducting Measurements of
Radon and Radon Decay Products in Schools and Large Buildings. A National Radon Safety Board
(NRSB) Radon Measurement Specialist (certification #14SS056) supervised the testing. Additional
information on radon management and the health effects of radon exposure is available from
www.montgomerycountymd.gov/dep/air/radon or www.epa.gov/radon.
KCI visited the site on December 21, 2015 and deployed one hundred thirty-nine (139) activated
charcoal (AC) radon test kits. KCI deployed radon test kits in frequently-occupied ground contact rooms,
and other areas, (if applicable) in accordance with AARST guidance. A floor plan map of the building
with the test locations is included as Attachment A of this report.
As a quality control measure, KCI included duplicate samples, field blanks, lab transit blanks, and office
blanks in accordance with AARST recommendations. In addition, KCI submitted six (6) test kits to
Bowser-Morner, Inc. as spike samples. The spiked tests were exposed to a known radon concentration by
Bowser-Morner prior to being returned to the laboratory for analysis.
KCI returned to the site on December 24, 2015 to retrieve the radon sampling test kits. KCI shipped all
radon tests via overnight delivery to Airchek, Inc. for analysis by gamma-ray spectroscopy. Airchek, Inc.
is a NRSB certified analytical laboratory for radon analysis (certification # ARL1402) located at 1936

Evaluation of Testing Conditions:
The operating condition that represents the greatest amount of significantly occupied time for this
building is; heating active, with outdoor temperature averages ≤ 65° F.
KCI concludes that the test period reasonably represents normal conditions when the building is
significantly occupied. Clear characterization of the radon hazard is most likely to be observed under this
normal operating condition. Based on the evaluation of test conditions, this test should reasonably
characterize radon hazards.
KCI also conducted observations of field conditions which could affect the results of the test and
compiled weather data for the testing period. KCI recorded observations of the following conditions in
each room at the time of deployment and collection of the radon test kits:
•
•
•
•
•
•
Indoor temperature,
HVAC Operation,
Dehumidifier operation,
Humidifier operation,
Ceiling fan operation, and
Open windows or doors.
Results:
The results of the radon test analysis indicated the following:
Radon Concentration
Room
None
≥4.0 piC/L
See Attachment B
<4.0 piC/L
Result
n/a
Notes:
D- Duplicate sample
All field blanks, office blanks, and lab transit blanks had test results of less than the laboratory detection
limit of 0.3 pCi/L. Review of the duplicate sample analysis indicates that adequate laboratory
measurement precision was achieved. The Spike sample analysis results indicate the laboratory is
operating within statistical control limits.
The sampling locations, field observations, and analytical results are listed on Table 1 (Attachment B).
The laboratory analytical results are also attached (Attachment C). Laboratory results and exposure data
for the spike samples are also included in Attachment C.
Our professional services have been performed in accordance with customary principles and practices in
the field of industrial hygiene and engineering. If you have any questions or comments regarding this
report, please feel free to contact me at (410) 316-7800.

Note: Spike samples are test canisters that are deliberately exposed to a controlled high level of radon in a laboratory.
They provide a quality control measure in the testing process and do NOT reflect radon levels in the building being
tested.
