Radon Review Quiz 6 (Mitigation) actual test 2023/2024

Radon Review Quiz 6 (Mitigation)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 - correct 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 - correct 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)?
