Detection limits vary from test to test, depending on the device used, the volume of the sample, the time employed and noise present on the gamma spectrum obtained.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-1765307840677473617.post-9251905761415921162011-11-03T18:41:43.666-07:002011-11-03T18:41:43.666-07:00@anon at 5:31PM, excellent.

T..."why was not happening on October 28?" Tepco did not say that it was not happening. Tepco used a measurement method with a very high detection limit on October 28, so that the amounts of Xe, if there were any, could not be detected. On November 1 and November 2, the detection limit was lowered and only then could the small quantity of Xenon be detected.
