At their February meeting the Audubon School Board was
updated on the Radon Testing that was conducted over Christmas break. Although Radon Testing is not currently
required for schools the administration and head custodian Brad Stroeher
thought that it would be a good idea to get a radon reading from both
buildings.
“With the remodeling project scheduled for this summer at
the elementary building it just makes sense for us to evaluate our Radon levels
in case we would need to install some additional equipment with our new HVAC
system,” stated Superintendent Gibbs.
Radon is a naturally occurring gas that is measure in pCi/L
(picocuries per liter). Levels can vary
throughout the year and may increase where soil has been disturbed such as when
new construction occurs. Long-term exposure to high levels of Radon has been
shown to cause cancer in some cases. The
Environmental Protection Agency has made the following recommendations
concerning indoor Radon levels:
Short-term
risk - .6 to 1.9 pCi/L
Further
Testing - 2.0 to 3.9 pCi/L
Action
Level - 4.0 and up pCi/L
The following radon levels were measured at the elementary
building:
Pre-K Room – 1.2 pCi/L
Room 106 -
1.5 pCi/L
Cafeteria -
2.2 pCi/L – Further testing recommended
Room 201 -
1.9 pCi/L
The following radon levels were measured at the 5 – 12
building:
Band Room - .8 pCi/L
Cafeteria - .8 pCi/L
Chemistry - 2.6 pCi/L – Further testing recommended
M.S.
Hallway - 3.8 pCi/L – Further testing
recommended
Although all testing sites were below the “Action Level” as
set by the EPA the school will do further testing over the summer. Legislation has been introduced this year in
Des Moines that would require schools to test for Radon beginning in 2025 and
every ten years after that. The state is
also talking about methods to provide funding to help districts that do need to
take action to lower Radon levels.
