Dear Hal and Marilyn Johnson:
You have elected to receive this radon detector and to pursue monitoring of
your home which was built under the requirements of the Northwest Energy
Code. The radon detectors and the evaluation of such detector are provided by
the Bonneville Power Administration at Bonneville's expense and at no cost to
you on a "one detector per dwelling unit" basis. The pursuit of radon
reduction measures or additional detailed monitoring is your responsibility
and is at your expense.
The following procedures shall be used in the installation and handling of
your radon detector:
1 . The radon detector shall be placed in the dwelling in accordance with
the following guidelines;
(a) Remove the detector from the aluminum packet. (The detector package
may be hung with the detector tag as long as it does not shield the
detector itself.)
(b) The detector shall be placed in a centralized living space, such as
living room, dining room, kitchen, den, family room, or hallway, etc.
(c) The monitoring location shall be on the first floor of the dwelling
completely above grade level .
(d) The detector shall be hung on the wall , placed on an open shelf, or
suspended from the ceiling 4 feet to 7 feet above the floor, away from
windows and doors, and away from possible drafts from heating or
cooling vents.
2. At the time the radon detector is placed in the dwelling, the date
should be written on the tag where indicated, denoted as Section 1 ,
Similarly, the date of removal shall be written in Section 4 of the
tag. DO fill out the monitor tag blanks pertaining to starting and
ending dates. DO NOT fill out the remainder of the tag. This area is
for agency use only.
3. The radon detector shall remain in place for at least three months
during the period September through March, but should not remain in
glace longer f ls,c lomonths456-3630 Personol Health 456-3613 Environmental Health 456-6040

4. When the monitoring period is completed, the radon detectors shall be
placed back in the aluminum packet that they came in. The top of the
foil packet shall be folded over and taped or held shut by similar
means. If the foil packet has been lost, then wrap the detector in
heavy aluminum foil to help reduce additional alpha particle
contamination during shipment. Mail or deliver the radon detector with
• the tag to the Spokane County Health District.
5. At least once a month, the Health District will submit all detectors
received from consumers to a processing agency. Results will be
returned to the Health District, and you will be notified by a "radon
results notification letter".
For more information, please call 456-6040.
