Note:

(1) Test with a 60μ Ci14C source 3mm from the detector.

(2) 1-hour instability test process: The count rate of detector acquisition was 10.0±0.5ks-1, the collection time of each data was set as 4min, and 15 data were collected cumulatively (1 hour) for each set of data. The absolute value of deviation between each value of each set of data and the mean value was calculated, and the three groups were tested continuously (3 hours). The maximum value of the three groups was the 1-hour operating instability test value. The maximum value is the one-hour operating instability test value . The maximum value is the 1-hour operating instability test value.
