NRPP Radon Measurements FlashcardsIf a sample of radon is taken from a room that is known to be at 125pCi/L and is kept in a well sealed container, what will the approximate radon activity be within the container after eight days? - correct answer 31.3 Radon decay products have (or )longer shorter half lives than radon gas? - correct answer Shorter The ionization of an otherwise electrically neutral atom is used in measuring radiation. Which process best describes ionization? - correct answer An uncharged atom gains or loses orbital electrons ()and becomes electrically charged. Give three characteristics of radon - correct answer Half life of 3.8 days Inert Can't sense (see, smell, or taste) Radioactive Naturally occurring Gas If a room within a home is determined to be at 25 pCi/L, what working level would be expected in this room using typical assumptions for equilibrium ratio in residential buildings? - correct answer 0.13 What is the highest working level that could be observed in a room having a constant radon activity of 10 pCi/L ? - correct answer 0.1 f a radon measurement is calculated to be 7.8456 pCi/L, what number should be written on the report to the client? - correct answer 7.8 pCi/L A building has very high internal air circulation rate and was measured at 0.03WL. What can be said about the radon concentrations? - correct answer The radon is probably more than 6 pCi/L.
