| 1.
| A short term test
using a Continuous Radon Monitor was conducted in a home. The result was
3.8 pCi/L.. What would be the proper response? |
| |
|
No action necessary your home is
safe. |
| |
|
The level is so close to the
action level you may want to test again in the future. |
| |
|
Mitigate the home. |
| |
|
Confirm the measurement with a
long term test. |

| A homeowner calls you
to mitigate their home. You discover that during the test period there
were winds in excess of 30 miles per hour and 2 inches of rain. Your
correct response would be: |
| |
|
The test is invalid and the
homeowner should arrange for a new test. |
| |
|
Since most homes in that area
have radon they should mitigate. |
| |
|
Perform passive mitigation and
re-test. |
| |
|
Offer to re-test at no charge
and if the levels are still 4pCi/l or above you will mitigate the
home. |
|
| 7.
| Alpha Track Devices
are typically used for what type of testing? |
| |
|
Short term testing. |
| |
|
Houses with no
basements. |
| |
|
As diagnostic measurements to
assist the mitigator. |
| |
|
Long term testing. |
|
| 8.
| A homeowner tells you
that the results of 2 radon LS devices, placed side by side resulted in
readings of 3.9pCi/L and 9.0 pCi/L. What is the correct response.
|
| |
|
The average is above 4pCi/L they
should mitigate. |
| |
|
The reading above 4 is greater
than double the reading below 4pCi/L. Therefore the results are outside
acceptable ranges. A re-test should be conducted. |
| |
|
Someone must have tampered with
the devices, a new test should be conducted. |
| |
|
The reading above 4pCi/L
indicates that there are high levels of radon and they should mitigate
immediately. |
|
