RE: Fridley Public Schools

Long-Term Radon Sample Results

IEA Project # 201611133

Dear Mr. Craft:

As requested by Fridley Public Schools, IEA placed 324 alpha track radon detectors for the purpose of

evaluating radon levels in specific areas of the following five (5) buildings in the district:

• Hayes Elementary – 65 detectors

• Stevenson Elementary – 62 detectors

• Fridley Community Center – 33 detectors

• Fridley High School – 81 detectors

• Fridley Middle School – 83 detectors

The purpose of the site sampling was to document radon levels in the sampled locations and to compare

them to the MDH and the EPA established recommended action level of 4.0 picoCuries per liter (pCi/L)

for frequently occupied areas.

INTRODUCTION

Radon is a colorless, odorless, radioactive gas that occurs naturally in soil, rocks, underground water

supplies, and in the ambient air. According to the U.S. Environmental Protection Agency (EPA) and

other scientific organizations, naturally-occurring radon gas has been associated with an increased risk of

developing lung cancer. The chances of developing lung cancer from radon exposure are dependent on

several factors, including individual susceptibility and, perhaps more importantly, the dose and duration

of exposure. Radon testing in schools is highly recommended by the Minnesota Department of Health

(MDH) and EPA. MDH recommends retesting following any renovations to the building or HVAC

system, and periodically (e.g. every five years).

Long-Term Radon Testing April 25, 2017

© IEA, Inc. Page 2 of 4

IEA placed alpha track detectors in frequently occupied areas district-wide for the purpose of sampling

for radon in accordance with the MDH’s Best Practices for Radon Measurement in Minnesota Schools

and Commercial Buildings (March 2013). A total of 324 detectors were put in place on December 29,

2016. A total of 295 detectors were retrieved on April 4, 2017, for a total long-term sampling period of

95 days. Twenty-nine (29) detectors were missing at the end of the testing period. The EPA and MDH

recommend radon testing of frequently-occupied school areas, areas identified by the district to place the

detectors were expected to be frequently occupied and would typically be used for radon sampling. IEA

followed MDH recommendations for quality assurance measurements by including duplicate detectors

and control detectors (blanks). The detectors were analyzed by Landauer, Inc. The sampling and analysis

methodologies are provided in Appendix A.

Per Minnesota Statutes, section 123B.571, school districts are now required to report radon test results at a

school board meeting and report results to the MDH. IEA is able to assist with presenting results to the

school board, and the MDH reporting. The MDH reporting form is provided in Appendix D.

EVALUATION CRITERIA

The MDH and the EPA have established a recommended action level in frequently occupied areas of 4.0

picoCuries per liter (pCi/L) for an annual average. Testing was conducted during the winter, as

recommended by the MDH, when the ventilation system was operating normally, and windows and doors

were closed. Consequently, sampling under these “closed” conditions should be considered “worst case.”

The MDH recommends follow-up testing for sampling results that are above the action level. Please refer

to the following table for MDH guidelines:

RESULTS (pCi/L) RECOMMENDED ACTION

LESS THAN 4 Consider re-testing after changes to foundation or HVAC and

every 5 years

EQUAL TO AND GREATER THAN 4 Conduct CRM short-term testing during winter months

LESS THAN 4 (DURING OCCUPANCY)

AFTER CRM TESTING

Repeat CRM testing if not conducted during winter or if

conducted during abnormal ventilation. Otherwise consider re-

testing after changes to foundation or HVAC and every 5 years

GREATER THAN 4 (DURING

OCCUPANCY) AFTER CRM TESTING

Reduce radon in rooms to less than 4 through radon mitigation.

Conduct CRM testing to verify radon reduction.

CRM: Continuous Radon Monitor

RESULTS & DISCUSSION

The laboratory report and maps of each building with sampling locations, are provided in Appendix B.

The Chain of Custody is provided in Appendix C. Following are summary results for each building.

Hayes Elementary

A total of sixty-five (65) detectors were placed at Hayes Elementary. Six (6) detectors, one each Room

127, South Gym, North Gym, Computer Lab, and two in Room 133, were missing when the detectors

were collected. The results for the other fifty-nine (59) detectors indicated that radon levels were below

the action level of 4 pCi/L. See Table 1 below for a summary of the results:

TABLE 1: Hayes Elementary RANGE OF RESULTS

0.0 – 1.9 pCi/L 2.0 – 2.9 pCi/L 3.0 – 3.9 pCi/L 4 pCi/L

Number of Tests 59 0 0 0 All below action level

pCi/L: picocuries per liter




Stevenson Elementary

A total of sixty-two (62) detectors were placed at Stevenson Elementary. Four (4) detectors, one each in

the Media Center Office, Room 115, Kitchen, and North Gym, were missing when the detectors were

collected. The results for the other fifty-eight (58) detectors indicated that radon levels were below the

action level of 4 pCi/L. See Table 2 below for a summary of the results:

TABLE 2: Stevenson Elementary RANGE OF RESULTS


Number of Tests 46 11 1 0 Room and measurement reading between 3.0 and 3.9 pCi/L: 116 - 3.0


Fridley Community Center

A total of thirty-three (33) detectors were placed at Fridley Community Center. Two (2) detectors, one

each North Office (2) and Room 135, were missing when the detectors were collected. The results for the

other thirty-one (31) indicated that radon levels were below the action level of 4 pCi/L. See Table 3

below for a summary of the results:

TABLE 3: Fridley Community Center RANGE OF RESULTS




Fridley High School

A total of eighty-one (81) detectors were placed at Fridley High School. Seven (7) detectors, one each in

Rooms 118, 122, 124, Weight Room, Phy Ed, East Gym, and the Media Center, were missing when the

detectors were collected. The results for the other seventy-four (74) indicated that radon levels were

below the action level of 4 pCi/L. See Table 4 below for a summary of the results:

TABLE 4: Fridley High School RANGE OF RESULTS




Fridley Middle School

A total of eighty-three (83) detectors were placed at Fridley Middle School. Ten (10) detectors, one each

in the Rooms 101, 106, 112, 127, 126, 133, C1 Gymnasium, M9, A2, and M8A, were missing when the

detectors were collected. The results for the other seventy-three (73) indicated that radon levels were

below the action level of 4 pCi/L. See Table 5 below for a summary of the results:

TABLE 5: Fridley Middle School RANGE OF RESULTS







CONCLUSIONS & RECOMMENDATIONS

The radon levels in the sampled locations were below the EPA action level of 4 pCi/L.

The EPA has established recommended guidelines for permissible radon concentrations in schools.

Though these standards are unenforceable at this time, they do provide a reference point to decide what

actions to take based on the radon level screened. The following are general recommendations for

frequently-occupied areas of schools:

• Since the results are less than 4 pCi/L, consider retesting if major changes are made to the buildings

foundations or HVAC systems and every 5 years.

• Report radon test results to the Minnesota Department of Health (MDH), using the MDH ‘School

Radon Testing Form’ in Appendix D.

• Report radon test results at a school board meeting.

GENERAL COMMENTS

The analysis and opinions expressed in this report are based upon data obtained from radon sampling

district-wide and are representative of the locations and time period sampled. This report does not reflect

variations in conditions that may occur across the site, property, or facility. Actual conditions may vary

and may not become evident without further assessment.

The report is prepared for the exclusive use of our client for specific application to the project discussed

and has been prepared in accordance with generally accepted environmental, health and safety practices.

Other than as provided in the preceding sentence and in our Proposal #5676 dated November 30, 2016

regarding EHS radon sampling services at the district locations, including the General Conditions

attached thereto, no warranties are extended or made.

Methodology

Sampling Methodology

IEA placed alpha track radon detectors designed specifically for the detection of alpha particle activity caused

by the decay of Radon-222 and its daughter products. The detector is made of an electrically conductive

material and contains an alpha-particle sensitive registration material or foil. The detector has a cylindrical

shape and completely encloses the foil. Air and radon gas can diffuse into the detector chamber through a

cellulose filter. Individual detectors are uniquely identified with a number and corresponding bar code.

Upon receipt at the analytical laboratory, detectors are logged in and unique numbers assigned to each

detector foil. Sample preparation is by an etching process. The foils are chemically etched after being loaded

into a multi-cell etching chamber.

All foils are checked for both background and sensitivity before being used, with rejected material being

discarded to prevent it from being used accidentally. During processing, a blank is included with each run.

Monitors exposed to known concentration are processed weekly. Blind tests, with monitors exposed to an

unknown level, are run twice each month with six replicates.

For each foil/monitor, the dose calculation program calculates the number of days the monitor was

exposed in the field. The program calculates the average track density (tracks per square millimeter)

subtracts a background track density and then multiplies by the calibration factor to give total integrated

exposure. This number is divided by the number of days used to derive the average radon concentration.

The minimum value reported is 0.1 pCi/L.

Any unusual conditions are noted on the processing form and shown on the exposure report. All

exposure reports are reviewed by the QA vice-president before being mailed to IEA.

Results received by IEA are again reviewed for completeness by the Laboratory Quality Manager.

Appendix D

MDH Reporting Form

School Radon Testing Reporting Form

General Instructions

According to MS 123B.571, radon testing conducted in public school buildings eligible for health and safety

(i.e., not charter schools) must be reported to the Minnesota Department of Health.

For the purpose of this form, a building is defined as an occupied facility that has a unique address, including

administrative buildings. A building could be a single structure or a complex of structures. For reference, all

district owned buildings entered on the Minnesota Department of Education “Facilities Age and Square

Footage Report” should be utilized.

Please submit information about the most recent round or cycle of testing conducted for each building, unless

this was already reported to MDH in the 4/4/11 survey. We do not need details of prior rounds of testing.

1. Submit summary information and raw data if either of the following apply:

a. Radon testing has been completed in a building since the MDH ‘School Radon Testing Survey’ dated April 4, 2011, or

b. Radon testing was completed at some time previously and your district did not report

radon testing in the MDH ‘School Radon Testing Survey’ dated April 4, 2011.

2. Complete one survey for each building tested

3. Submit the survey, raw data (e.g., laboratory analysis report) and a building map to MDH by

email, to [email protected]

4. If follow-up testing, mitigation, and/or post-mitigation testing is not yet completed, please

submit a completed form and raw data when the work is completed.
