A measurement of the differential pressure across a slab is
carried out by a mitigator on a day characterized by gusts
of wind. In comparison to measurements made on a calm
day, the windy day pressure differential readings across
the slab will:
Select one:
a. Remain constant
,b. Increase
c. Fluctuate
d. Decrease - ANSWER-c. Fluctuate
A mitigator is called to a house with a basement that has a
radon reading of 20 pCi/L. Half of the basement is
finished, and it has parquet flooring. Since all diagnostic
testing is to be performed, which of the following would be
the most logical test to perform FIRST?
Select one:
a. Suction-field extension testing in the unfinished portion
of the basement, with one or two vacuum-cleaner suction
holes, and with pressure-test holes at distances of 1, 5,
,10, and 15 feet in at least two directions away from each
test hole.
b. Suction-field extension testing, with one vacuum-
cleaner suction hole each in the finished and unfinished
portions of the basement, and four pressure-test holes
(one in each corner) in each portion.
c. Sub-slab radon concentration measurements, through
three or four sample holes each in the finished and
unfinished portions of the basement.
d. Suction-field extension testing in the unfinished port -
ANSWER-d. Suction-field extension testing in the
unfinished portion of the basement, with one vacuum-
cleaner suction hole, and one to four pressure-test holes
at remote corners of the unfinished portion.
, A Pressure Field Extension (PFE) diagnostic test has been
conducted with a vacuum cleaner attached at preferred
sub-slab suction point via a 2-foot length of 3-inch pipe.
Three pitot tube measurements to determine air volume
were made with results of 0.045, 0.036 and 0.058 inches
of water column. How much air is being extracted by your
shop vacuum (assuming an air temperature of 70 degrees
F)?
Select one:
a. 41 CFM
b. 5,828 CFM
c. 72 CFM
d. 88 CFM - ANSWER-a. 41 CFM
