Baker:
We have now put through a purchase order No. 277158 for the two
tellurium-132 generators. As suggested in your letter of January 27th,
we are requcsting that the first penerator, on arrival at Hawaii
February 27th, contain 10 mCi.
(This would mean that on February 24th,
the generator would be a 20 mCi one.)
The second generator would
contain 5 mCi on arrival at Hawaii March 19th. We have calculated
that these amounts should provide us with the necessary 1327, As
you suggested, we will use the 0.01 M sodium thiosulfate in 0.01 M
ammonium hydroxide.
|
Mr. Powell Richards of our laboratory called you some time ago with
regard to standardization and it appears that we will have to use
the decay factor. He indicated that the average recovery factor
would possibly average around 60 percent of the calculated amount.
Without any reference standard, this seems to be the only method
that we can use to calculate a “ballpark" dose. Should you have
any standards available that would be helpful such as 1 Cs, please
let me know. We will carry along a 131; simulator for instrument
calibration purposes.
If you have any further suggestions, please let me know. I will
appreciate your handling this shipment expeditiously and I will
make the necessary arrangements with the AEC at Honolulu to receive
these shipments and transship them to me. The address in Honolulu
to which the shipment should go is to Mr. William B. Hills, Director,
Pacific Area Support Office, U. S. AEC, P. 0. Box 9186, Honolulu,
Hawaii 96820.
Sincerely,
