Series Description: This record series contains requests for radiochemical analyses, analytical reports, and related documentation. Files are arranged numerically and range from 3050 to 6560. Most files pertain to counting analyses for uranium and plutonium, although cesium-137 analyses appear infrequently. Each folder is labelled with the request number and the last name of the person making the request. Documents present in each file may include "Request for Control Analysis" or "Request for Analytical Services," both for samples with less than 50 milligrams concentration of fissionable material; "Control Worksheet-1"; "Control Worksheet-3 X-Ray Fluorescence Analysis"; "Counting Data Sheet"; and a computer printout of results. Information includes the name, building, and phone number of the requestor; date submitted to the lab; original sample size; charge number; sample code; desired analysis; series; analyst's name or initials; completion date and time; supervisor's approval;concentration estimate; curve factor; nature and estimation of activity; concentration of all constituents of the sample; dilution information; aliquot size; absorbance; net counts; detector type; live time seconds; voltage; amp setting; results; and comments. Some files contain analytical results for gross alpha surveys. Matrices tested include liquids, air, and dust. Results are expressed in becquerels per gram (Bq/g); becquerels per milliliter (Bq/ml); grams per liter (g/L); or counts per minute per milliliter (c/m/ml). Graphs of analytical results are included.

Box 2902 contains a file titled "Inactive Tank Farm Data Sheets (Misc.)" which includes a "Checklist for Analysis of Inactive Waste Storage Tank Liquid Samples" consisting of a list of possible analyses; spaces for information relating to the distribution of samples, completed analyses, and results reported; sampling date; tank identification; sample identification numbers; and analytical request numbers. A notebook titled "ORNL Inactive Waste Tanks, Sampling and Analysis Samples" lists the date logged, the sample code, the request number, the date and amount of sample transferred, and the receiver's initials. The analytical information for the samples mentioned in these two documents is found in boxes 2902 and 2903.
