Chi Square values are given in the following table for 5, 10, 15, and 20 repetitions.
The Chi Square Test results should fall between the 0.95 and 0.05 probability values
in the table below almost all of the time. The more stringent 0.90 and 0.10 values are

Table 9-2
If the Chi-Square value is out of range, check the following:
• The positioning of the rod source.
• Ensure that there are no other sources (including dosed patients) in the area.
If a problem is found with any of the two items above, then correct the problem and
repeat the Chi Square Test.
If no problems are found with the above items, the out of range Chi Square value may
indicate a problem with the counter/timer mechanism of the system or the detector
itself. Contact Capintec’s only Authorized Service Center for service.
