The following constitutes the current-Monthly Progress Report for the' Environ--

mental-Radiological' Monitoring. Program conducted at the Byron Nuclear Power Stati0n, Byron,- Illinois.

Results of completed l. analyses are. presented

q in.the: attached-tables.

Missing entries indicate analyses that are-not Jcompleted and the results will appear in subsequent reports.

Data obtained in the program are well within the-ranges previously encountered inithe program and-to be expected in the environmental media sampled.

NoneLof-;t the-' media sampled : this month contained _ radioactivity attributable to the-constructionfof Byron-_ Nuclear Power Station.

Forf all gamalisotopic;' analyses; spectrum:is computer scanned from 80 to 20481 kev.- _ Specifically! included L are Mn-54, Co-58, Fe-59, - Co-60,.Zn -65,1 Zr -95,:
