Subject:
.161C TLD Monitorirn at West Valley, Ib.trth Quarter,1990 Enclosed is a ocpy of the TLD monitorirg results atnind the subject facility for the fourth quatter of 1990.
The large value noted for Station RJ is due to the proximity of this dosimeter to a waste storagc facility located at the site. Similar results have boon noted for each monitoring period.
Due to the high value normally recotikd at Station ihmter 11, the total exposure is the sum of tho values recorded on two TLDs, one of Wich is placed for the first half of the quarter, and the other for the secord half. 'Iho TID for the second half of the fourth quarter could not be located; thus the gruss exposure reported here is for roughly the first half of the quarter (Oct. 4 -
1 Nov. 10, 1990). A not value was not calculated.
