3 Terms and Definitions

The following terms and definitions apply to this section. 3.1 At a given geometry, 1mL solution contaminated by the measuring device measured, after the dead time and background corrected count rate. Unit is Counts/(min · ml) [(min · mL) -1]. 3.2 After decontamination surface of the sample, at a given geometry by means of measuring the residual radionuclides measured count rates. Unit count / Minute (min-1). 3.3 The arithmetic mean of five samples of the same radionuclide contamination measured count rates of each residue. Units of counts/minute (min-1). 3.4 The average count rate correction residual value. Units of counts/minute (min-1). A correction factor α reference [-1 3 × 106 (min · mL)] and count rate ratio test solution contaminated odds ratio count rates. The correction factor is the difference between the introduction of contaminated liquid ratio in order to correct the count rate used by different laboratories between.
