Radon Measurement Certification test actual questions and answers
What is this test? Ans✔✔- Absolute bullshit filled with trick questions, and cheap verbiage meant to
trick and deter takers
The four Soil Suction Mitigation techniques Ans✔✔- Subslab suction,
drain-tile suction,
sump-hole suction,
or block-wall suction
What is an Alpha Particle? Ans✔✔- Two neutrons and two protons bound as a single particle emitted
from the nucleus of certain radioactive isotopes in the process of decay.
Closed House Procedures Ans✔✔- During any short-term test, closed-house conditions should be
maintained as much as possible while the test is in progress. In tests lasting fewer than four days,
closed-house conditions should be maintained for at least twelve hours before starting the test, as well
as for the duration of the test. While closed-house conditions are not required before starting tests
lasting between four and ninety days, they should be maintained as much as possible.
Curie Ans✔✔- a standard measurement for radioactivity, specifically, the rate of decay for a gram of
radium at 37 billion decays per second; a unit of radioactivity equal to 3.7 x 1010 disintegrations per
second.
Equilibrium Ration Ans✔✔- At complete equilibrium (i.e., at an equilibrium ratio of 1), 1 WL of RDPs
would be present at the radon concentration of 100 pCi/L. The ratio is never 1 in a house; due to
ventilation and plate-out, the RDPs never reach equilibrium in a residential environment. A commonly
assumed equilibrium ratio is 0.5 (i.e., the decay products are halfway toward equilibrium), in which case
1 WL would correspond to 200 pCi/L. However, equilibrium ratios vary with time and location, and ratios
of 0.3 to 0.7 are commonly observed.
