If a sample of radon is 31.3
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?
Radon decay products Shorter
have (or )longer shorter
half lives than radon gas?
The ionization of an An uncharged atom gains or loses orbital electrons
otherwise electrically ()and becomes electrically charged.
neutral atom is used in
measuring radiation.
Which process best
describes ionization?

If a room within a home is 0.13
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?
What is the highest 0.1
working level that could
be observed in a room
having a constant radon
activity of 10 pCi/L ?
f a radon measurement is 7.8 pCi/L
calculated to be 7.8456
pCi/L, what number
should be written on the
report to the client?
A building has very high The radon is probably more than 6 pCi/L.
internal air circulation rate

0.03WL. What can be said
about the radon
concentrations?

Within the U.S, the EPA 1.3 pCi/L
believes the average
annual indoor radon
activity to be:
What would be the 0.02 WL
expected working levels
in a room at 4 pCi/L, using
typical assumptions for
equilibrium ratio in
residential buildings?
In order to calculate the Results of simultaneous measurements of radon and
equilibrium ratio in a home radon decay products.
you need to know:
Lung cancer risks exist True
with exposures to radon
concentrations below
4pCi/L.
Short-term measurements False
can be factored by the
time of deployment to
determine a year-long
average.
The results of a short- False
term, closed building test
indicates the highest the
radon could ever be.
Radon is only a concern in False
homes, not in schools and
workplaces.
When emitted within the alpha particle
lungs, which one of the
three ionizing radiation
types causes the most cell
damage within the lung?
