Classification: CPC G | IPC G

Claim 7:
8. The measurement apparatus of claim 1, wherein:
the first nonlinear transfer function is based on an oil waste mass calibration model expressible as M=b2(POWS)2+b1(POWS) where:
output M is a mass (in grams) of the oil waste solids;
b2 and b1 are percentage to mass (P2M) calibration factors for a combination of oil waste solids; and
POWS is the percentage of oil waste solids determined by selecting a graduated marking on the BS&W tube nearest to a top level of the oil waste solids; and

the second nonlinear transfer function is based on a radioactivity level calibration model expressible as R=c2(CPM)2+c1(CPM) where:
output R is a radioactivity level in picoCuries;
c2 and c1 are radioactive level (RL) calibration factors for radioactive oil waste solids of the type being tested; and
CPM is a detection count rate in counts per minute determined using the radiation detectors.
