ii. To input the Isotope Efficiency, click in the appropriate text box (I 131, I 125 or I
123) and input the known efficiency value (0.001-100%).
iii. To input the I 131/ I 125 or I 123/I 125 Cross Contamination ratios, click in the
appropriate text box and input the known ratio (0.0001-1).
iv. To save the added information and return to the Bioassay Setup screen, click the
button or press Alt+D. Otherwise, click the button or press
Alt+C to return to the Bioassay Setup screen without saving the changes.
Note: Input for Cross Contamination ratios is required. If these boxes are left
blank, the
button is inaccessible.
c. To save the information on the Bioassay Setup screen and return to the main
Bioassay screen, click the
button or press Alt+D. Otherwise, click the
button or press Alt+C to return to the main Bioassay screen without
saving the changes.
Note: The following fields are required before the
button is accessible:
Investigation Level for each selected isotope, Counting Time and Probe
Distance.
Efficiency for all selected isotopes must be set in the Setup so that Bioassay
report results will be in units of activity. If Efficiency fields are left blank,
Bioassay results will appear as counts per minute (cpm) only.
