Table Name: ERM_RESULT

Description: The amount, activity, or concentration measured. Amounts can be zero, non-detect (ND), positive or negative. A negative result occurs when random effects and limitations in the measurement process cause the measured value for the sample to be less than that of the laboratory blank or background, which is subtracted from the sample measurement. Although negative radioactivity is physically impossible, the inclusion of negative results allows better statistical analysis of the data.
