3. CONDUCT OF OPERATIONS: a. The Field Radiation Support Team, in its eapacity of implementing the radiological protection program discussed in Tab C (not included herein), will collect urine samples, air sample filters, nose swipes, etc., which may be analyzed by the RAD LABfor fast turn around results. These samples will be sealed in appropriate containers, eg., plastic bottles or plastic bags. Samples are to be supplied with proper identification and accompanied by completed data forms. They will be delivered to the sample preparation trailer in the RAD LAB complex. Soil samples taken on the northern islands also will be sealed and identified in appropriate containers, and delivered to the sample preparation trailer. b. All samples received will be bagged and prepared for analysis. Soil samples will be processed so that the sample will be homogenized. An aliquot will be taken from the processed sample for analysis by wet chemistry. The remainder of the homogenized sample will be stored for the duration of the project in case additional analysis is required. e. The chemistry trailer is a minimal facility equipped to handle an estimated 10 soil samples/day. Chemistry techniques will be applied to prepare these and other samples for subsequent counting. d. The radiation measurementstrailer will have two multichannel analyzers which can be applied to two of four available detection systems: intrinsic germanium, sodium iodide, alpha spectrometer, and FIDLER. The trailer will also contain low level alpha and beta counting, liquid scintillation, and large area alpha and beta counting systems. The radiological counting of a sample will be performed by one or more of these systems, Appropriate mathematical calculations will be performed to convert sample counts to the desired units. This facility will be equipped with health physics equipment to support the laboratory operations and other limited functions on the Atoll. e. Samples will be processed in batches so that blind samples of spiked blanks and splits may be processed simultaneously for purpose of quality control. A written quality assurance manual for RAD LAB operations will be developed for the approval of the ERDA ERSP Manager. Quality control results will be documented. f. A written procedures manual, approved by ERDA, for sample preparation, chemistry, and counting, will be developed and maintained. Analysis will conform to this manual or to approved modification.* g. Two FRST team members will be assigned to the function of instrument maintenance. If required, they will be supplemented by personnel from the maintenance trailer. There will be operational equipment spares in the forward area (northern islands), however, the major inventory of spares for FRST team instrument support will be maintained in the maintenance trailer. h. All radioactive calibration sources, other than license exempt, will be controlled by the RAD LAB in accordance with the procedures of appropriate chapters of the ERDA Manual. An inventory of these sources will be furnished the Enewetak Radiological Protection Officer (RPO). ij The ERDA contractor, Eberline, will be responsible for the RAD LAB and instrument maintenance facilities. Military personnel will facilities. (See chart C-2-D-1-1, shown herein as Figure E-5.) be employed in these js The instrument maintenance facility will support the field in situ van operation for repair and calibration as required. This will include appropriate test equipment and ordinary spare parts. Unique spares for the system will be furnished by the ERDAin situ van contractor (EG&G). *See Appendix B of this report. E -7
