HIGH LEVEL SAMPLE PREPARATION DOE/ERSP PROCEDURE NO. 16 APPROVED: DATE DRAFTED: 30 January 1978 11 February 1978 by Don R. Martin (ERSP Manager) 1 Samples with 2400 pCi/g gross alpha will fall in this category. 2. These samples will not be ballimilled but merely homogenized. 3. The samples will be dried in sample can and homogenized in special hood area. 4, An aliquot of approximately 100 grams will be transferred to a petri dish (100 x 20 mm) and et under special hood area and taken to count room for gamma determination of Depending on 241 Am activity: a. A small portion of soil is transferred to a beaker (approximately 0.1 grams) under a hood b. Add 243Am and 236py as internal tracers. e. Sample is then processed through chemistry to determine ratios of 241A4m to 238pu and to 239,240py, area; no weights are needed. Note: While working with high level samples, respirator, gloves, and lab coat must always be worn. All materials used to process these samples, such as glassware, drying pan, gloves, crucible, ete., shall be discarded into container marked "RAD WASTE", A-16-1
