What is the least number of components of a given type that must be tested to
obtain the desired level of confidence in the results throughout the multi-family
housing development? -ANSWER-40
T/F You do not need to complete all XRF testing to conclude that all components
in a given component type are negative for lead. -ANSWER-False - if most
components are found to be positive for lead, you can conclude that all the
untested components are also positive for lead; however, the opposite does not
apply
,The decision that lead is present at or above 1.0 mg/cm2 is reached if ___percent
or more of the components are positive. -ANSWER-15%
The HUD Guidelines recommend that the housing owner or client evaluates the
quality of a lead based paint inspection by employing what? -ANSWER-direct
observation
on-site results
repeat testing
time and motion analysis
During repeat testing, how many testing components should be included in the
scope of work? -ANSWER-10
If the difference is less than the retest tolerance limit, the inspection has...? -
ANSWER-Passed the retest
If the difference of the overall averages equals or exceeds the retest tolerance
limit, this procedure should...? -ANSWER-Be repeated with ten new testing
combinations
The EPA work practice standards define an inspection as...? -ANSWER-A surface-
by-surface investigation to determine the presence of lead based paint.
T/F Any paint that is not sampled or tested must be assumed to be lead based
paint. -ANSWER-True
,The HUD Guidelines emphasizes the importance of collecting paint chip samples
so that the dimensions of the surface area of paint removed can be measured
accurately to within___? -ANSWER-1/8th of an inch
Paint chip analysis can be done using...? -ANSWER-FAAS
ICP-AES
FAAS -ANSWER-Furnace atomic absorption spectroscopy
ICP-AES -ANSWER-Inductively coupled plasma emission spectroscopy
The laboratory can report the results of the lead levels in what two units? -
ANSWER-mg/cm2
ug/g, ppm, weight percent or mg/kg
What is the recommended unit of measurement for lab samples per HUD
guidelines? -ANSWER-mg/cm2
NLLAP -ANSWER-National Lead Laboratory Accreditation Program
What are the two organizations that can evaluate and recognize laboratories? -
ANSWER-A2LA and AIHA

The source of radiation in XRF analyzers is...? -ANSWER-cobalt-57 isotope
cadmium-109 isotope
Fluorescence -ANSWER-When x-rays and gama rays are rleased from an XRF
analyzer and hit a painted surface, the elements in the paint (including lead) are
excited and respond by emitting energy in the form of x-rays characteristic of
each of the elements.
The different orbits ("shells") in an atom are labeled sequentially with letters
staring with...? -ANSWER-K, L, M, N, O, P, etc
Which shell is closest to the nucleus? -ANSWER-K
T/F Going outward in the electron shells, electrons are more tightly bound, and
thus have more difficulty being ejected from their orbit or shell. -ANSWER-False -
the electrons are more loosely bound making it easier to eject from their shell
Half-life -ANSWER-The time it takes half of the materials to decay into another
radionuclide or element
What is the half life for cobalt-57? -ANSWER-9 months
