6. 5.1/1'1 Add the following sentence to the end of the first paragraph.

A total of 73 TLD locations measured direct radiation around the station during 1991.

7- 5.1/1 1 Add the following statement to paragraph 1. +

However, since the charcoal cartridges used to capture airborne I-131 were counted in batch mode, that is more than cae at a time, it is possible that approximately 10% of the samples did not attain the design LLD of 0.07 pC1/m3 , the Average LLD of those cartridges was approximately 0.09 pCi/m3 . It should be noted that charcoal cartridges are routinely analyzed from nine locations, the 00CM requires only five.
