Radon Testing

The Oregon Health Authority's Healthy and Safe Schools (HASS) Plan promotes transparency around how radon is addressed by school districts, ESDs, and charter schools which includes a Radon Testing Plan and posting Radon tests results. Radon is clear, odorless, radioactive gas that can be extremely harmful to people. Radon exposure is the leading cause of lung cancer among non-smokers. To reduce student and staff exposure to radon, Oregon law requires school districts to test for elevated levels of radon once every ten years.

Radon Testing 2024-25

Davis Elementary School

PBS Engineering and Environmental Inc. (PBS) performed short-term radon testing from November 12 through 14, 2024 the Library and Room 22 within Davis Elementary School in Portland, Oregon. This was performed following initial short-term radon testing and subsequent renovations of the spaces.

PBS Engineering and Environmental Inc. (PBS) performed real-time radon testing from November 22 through 24, 2024 in the Library and Room 22 within Davis Elementary School in Portland, Oregon. This was performed following initial short-term radon testing using passive radon monitors which indicated average concentrations of radon between four and eight picocuries per liter (pCi/L) of air.

If the result is less than 2.0 pCi/L, school districts are required to test again every 10 years, per Oregon Revised Statute 332.166-167.
If the result is between 2.0 pCi/L and 4.0 pCi/L, consider fixing (i.e., lowering) the radon in that room.
If the result is from 4.0 pCi/L to 8.0 pCi/L, perform a follow-up measurement of that room using a long-term test. This test should be conducted over as much of a nine-month school year as possible, when the room is likely to be occupied. If that result is equal to or greater than 4.0 pCi/L, the radon in the room should be fixed (i.e., lowered).
If the initial short-term test result is equal to or greater than 8.0 pCi/L, conduct a second short-term test and average its result with the initial short-term test result. If the average of the two is equal to or greater than 4.0 pCi/L, radon in the room should be fixed (i.e., lowered).

CONCLUSIONS AND RECOMMENDATIONS

Library

Average concentrations of radon exceed the action level during occupied hours. Therefore, steps should be taken to reduce occupied-hour radon concentrations.
Fresh air ventilation should be increased during occupied hours and the room should be retested.

Room 22

Average concentrations of radon were slightly below the action level during occupied hours.
As radon concentrations were above action levels for much of the test period, The District should consider increasing fresh air ventilation during occupied hours.

Margaret Scott Elementary School

PBS Engineering and Environmental Inc. (PBS) performed short-term radon testing from November 12 through 14, 2024 in room 10 within Margaret Scott Elementary School in Portland, Oregon. This was performed following initial short-term radon testing and subsequent remedial actions.

If the result is less than 2.0 pCi/L, school districts are required to test again every 10 years, per Oregon Revised Statute 332.166-167.
If the result is between 2.0 pCi/L and 4.0 pCi/L, consider fixing (i.e., lowering) the radon in that room.

H.B. Lee Middle School

PBS Engineering and Environmental Inc. (PBS) performed short-term radon testing from November 12 through 14, 2024 in room 606 of HB Lee Middle School in Portland, Oregon. This was performed following initial short-term radon testing and subsequent renovations of the space.

If the result is less than 2.0 pCi/L, school districts are required to test again every 10 years, per Oregon Revised Statute 332.166-167.
If the result is between 2.0 pCi/L and 4.0 pCi/L, consider fixing (i.e., lowering) the radon in that room.

HOLLA

PBS Engineering and Environmental Inc. (PBS) performed short-term radon testing from November 12 through 14, 2024 in five spaces within HOLLA School in Portland, Oregon. This was performed following initial short-term radon testing and subsequent renovations of the spaces.

If the result is less than 2.0 pCi/L, school districts are required to test again every 10 years, per Oregon Revised Statute 332.166-167.
If the result is between 2.0 pCi/L and 4.0 pCi/L, consider fixing (i.e., lowering) the radon in that room.
If the result is from 4.0 pCi/L to 8.0 pCi/L, perform a follow-up measurement of that room using a long-term test. This test should be conducted over as much of a nine-month school year as possible, when the room is likely to be occupied. If that result is equal to or greater than 4.0 pCi/L, the radon in the room should be fixed (i.e., lowered).
If the initial short-term test result is equal to or greater than 8.0 pCi/L, conduct a second short-term test and average its result with the initial short-term test result. If the average of the two is equal to or greater than 4.0 pCi/L, radon in the room should be fixed (i.e., lowered).

PBS Engineering and Environmental Inc. (PBS) performed real-time radon testing from November 22 through 24, 2024 in Storage 127 (formerly Zyberg Office) within HOLLA School in Portland, Oregon. This was performed following initial short-term radon testing using passive radon monitors which indicated average concentrations of radon exceeding eight picocuries per liter (pCi/L) of air.

CONCLUSIONS AND RECOMMENDATIONS

Based on the above results, it appears likely that the initial elevated result was due to the inappropriate placement of the test device. Actual radon concentrations remained low throughout this follow-up test period.
This room may be returned to service.
