Mr. Patrick T. Hankard
Director of Building Maintenance
South Windsor Public Schools
1737 Main Street
South Windsor, CT 06074
Dear Mr. Hankard:
The results of recent radon testing in the South Windsor
school buildings are enclosed. You will find one or more pages
for each building presented in a format suitable for posting.
Radon-in-air samples were collected following protocols
suggested by the U.S. Environmental Protection Agency (EPA) in
their publication "Radon Measurements in Schools, An Interim
Report" , March 1989 . Charcoal samplers, manufactured and analyzed
by Air-Chek, 180 Glenbridge Road , Arden, NC 28704, were placed in
classrooms and other frequently used rooms on and below ground
level . The results provide a "background" survey which can be
used to indicate whether a potential problem exists.
As you review the survey, keep in mind that the EPA
protocols are just guidelines at this time. While the Connecticut
State Department of Education recommends that schools be tested,
neither state nor federal regulations have been developed to
require schools to be evaluated for radon and mitigated as is the
case for asbestos. Also, the screening measurement does not
represent the long-term average radon level to which school
children and teachers are exposed. If elevated levels are found
with a screening measurement, there are two important reasons why
no funds should be expended to reduce radon levels before making
confirmatory or diagnostic measurements. First, there is always
the possibility that a single measurement may be faulty. Second,
radon levels fluctuate so greatly that a single measurement may
be made during an unusual peak in the radon concentration. Making
a second measurement will better assess the levels to which
students are routinely exposed.
The EPA standard for radon-in-air is 4 pCi/L. The EPA
currently feels that no further action is indicated when results
this low are obtained. Although exposures in this range do
present some risk of lung cancer, no remedial measures are
recommended since reduction of levels this low may be impossible
to achieve. According to the EPA, 4 pCi/L is equivalent to a
HYGIENE & SAFETY SERVICES
little more than 200 chest x-rays per year and would result in
between 1 and 5 lungcancer deaths per 100 people exposed over -a
70 year period. The Congress has set a national goal for indoor
radon concentrations to match outdoor ambient levels (0.2 to 0. 7
pCi/L) .
The current EPA recommended actions, based on results of
screening measurements, are as follows:
Screening Measurement Result Recommended Action
less than 4.0 pCi/L Follow-up measurements are probably not needed, but may be made at
the discretion of school officials. When using short-term
measurements, average radon concentrations can vary by a factor of
2 or 3. The possibility of reducing radon levels must be evaluated
on a case-by-case basis.
between 4 and 20 pCi/L Perform long-term follow-up measurements over the next 12 months.
If confirmed, action should be taken within several months to
reduce radon levels as far as possible.
between 20 and 100 pCi/L Perform short-term follow-up measurements within several months.
If confirmed, action should be taken within several weeks to
reduce radon levels as far as possible.
over 100 pCi/L Perform short-term follow-up measurements immediately. Contact the
appropriate state or local health officials to determine if
temporary relocation is needed until the radon level can be
reduced.
Based on the above recommendations, no further action is
needed at this time. All of the measured radon levels were below
4.0 pCi/L.
You will find three sample numbers missing from the reports.
Sample 6 from Ellsworth was reported as " improperly sealed. Air
infiltration invalidated the test. " Samples 12 and 14 from
Timothy Edwards were eliminated from the list because the
laboratory shipment contained only 248 kits rather than the 250
ordered.
Please do not hesitate to call if you have any questions.
Sincerely yours,
7
