Radon Measurement Certification test correctly answered 100%

Radon Measurement Certification testWhat is this test? - correct answer Absolute bullshit filled with trick questions, and cheap verbiage meant to trick and deter takers The four Soil Suction Mitigation techniques - correct answer Subslab suction, drain-tile suction, sump-hole suction, or block-wall suction What is an Alpha Particle? - correct answer 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 - correct answer 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 - correct answer 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 - correct answer 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. Picocurie (pCi): - correct answer one pCi is one-trillionth of a curie, 0.037 disintegrations per second, or 2.22 disintegrations per minute.
