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

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.

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
