Radon Testing Results

Eugene School District 4J is testing all schools for radon in 2018–19. The district has engaged an independent professional environmental service to conduct the radon testing.

Testing began in November 2018 and will be completed at all district schools over the following months. Results of the tests will be posted on this webpage. Note: As new buildings come online, radon testing will be performed and results posted here.

The Environmental Protection Agency and the Oregon Health Authority recommend that where an initial short-term test indicates a radon level at or above 4.0 picocuries per liter of air (pCi/L), a follow-up measurement using a long-term test should be conducted. If the long-term measurement shows a level of radon above the recommended action level of 4.0 pCi/L, EPA recommends taking corrective measures to reduce radon levels.

¹Howard Elementary School, room 138 (community room): Long-term testing indicated levels at 4.3 and 4.0 pCi/L*, which are slightly above/at the recommended action level of 4.0 pCi/L, requiring follow-up correction and re-testing. As recommended, a concrete slap seal was installed and follow-up short-term testing is scheduled for the 2021–22 school year.
UPDATE (10-28-21): Remediation efforts were successful. No elevated levels of radon were detected in the post-remediation testing.
²Spring Creek Elementary School, staff room: Long-term testing indicated levels at 6.7 and 7.6 pCi/L*, which are above the recommended action level of 4.0 pCi/L, requiring follow-up correction and re-testing. As recommended, a correction on a slab joint was performed and follow-up short-term testing is scheduled for the 2021–22 school year.
UPDATE (10-28-21): Initial remediation reduced radon levels, but follow-up testing showed slightly elevated radon levels at 4.4 and 4.5 pCi/L.* Additional remediation was performed—a couple of small pipe penetrations at the wall heater (inside the wall cavity) were sealed and  exhaust fan is programmed to run for two additional hours each day. Follow-up testing is planned.
UPDATE (3-10-22): Additional remediation efforts were successful. No elevated levels of radon were detected in the post-remediation testing.
³North Eugene High School, rooms 312 and 600: Long-term testing indicated levels below the recommended action level of 4.0 pCi/L, thus no follow-up is necessary.
⁴4J Education Center:
– TSS supervisor office: Long-term testing indicated levels below the recommended action level of 4.0 pCi/L, thus no follow-up is necessary.
– Custodial/grounds conference room: Long-term testing indicated levels at 7.9 and 8.2 pCi/L*, which are above the recommended action level of 4.0 pCi/L, requiring follow-up correction and re-testing. Corrective action and follow-up short-term testing are scheduled for the 2021–22 school year. UPDATE (3-10-22): Remediation efforts were successful. No elevated levels of radon were detected in the post-remediation testing.
– Custodial equipment repair shop: Long-term testing indicated levels at 6.0 and 4.3 pCi/L*, which are above the recommended action level of 4.0 pCi/L, requiring follow-up correction and re-testing. Corrective action and follow-up short-term testing are scheduled for the 2021–22 school year. UPDATE (3-10-22): Remediation efforts were successful. No elevated levels of radon were detected in the post-remediation testing.

⁵ Edison Elementary School, PE Storage and Office room 191: Short-term testing indicated levels of 4.1 pCi/L on 12/5/22 and 4.9 pCi/L on 2/6/23 (average of 2 test samples), which are slightly above the recommended action level of 4.0 pCi/L, requiring follow-up correction and re-testing.  Remedial action is scheduled for Spring Break 3/27/23- 3/31/23.  Slab penetrations and slab joints will be sealed and re-testing will be scheduled.

*For context, the EPA recommends school officials consider relocating individuals in rooms that have radon levels near 100 pCi/L.
