RADON CHAPTER 8 – QUESTIONS AND ANSWERSA client expresses concern because, during a 7-day charcoal canister short-term test, a
brief thunderstorm passes over the home. Which of the following would be the MOST
APPROPRIATE response to give this client? - Answers -Since the measurement period
is 7 days, the test will still be valid.
A post-mitigation radon measurement device should be placed: - Answers -in the same
location as the pre-mitigation test device.
According to EPA Measurement Protocols, a single radon test is acceptable for a real
estate transaction under which of the following conditions? - Answers -A 48-hour
measurement with an active continuous monitor which can integrate and record a new
result hourly or less.
According to the simultaneous test option for real estate transactions, when one result is
greater than 4 pCi/L and the other result is less than 4 pCi/L, a re-test is recommended
if the: - Answers -higher result is greater than twice the lower result.

How close to one another must two charcoal detectors be placed if they are to be
considered collocated test devices for real estate testing? - Answers -4 inches
In a real estate test, two activated charcoal canisters measured 1.5 pCi/L and 5.5 pCi/L
after exposure for 48 hours at opposite ends of an occupied basement. The client
should be informed that: - Answers -When two collocated passive devices (4 inches
apart) are on opposite sides of the 4.0 pCi/L guidance the results should not vary more
than 2-fold. In this case one is above 4 and the other is below 4 AND 5.5 is more than
two times the lower result of 1.5. Because of this wide variation the results are to be
thrown out and the test repeated.
The correct answer is: The two results are too far apart and should be discarded
altogether.
