PRIORITY TEN2 MSG909 PAGE 02 295 2158 (TOTAL OF 3 SYSTEMS IN LAB). - ADD 1 MORE GAMMA COUNTING SYSTEM (USE IMP SPARE SYSTEM). EIGHTEEN MONTHS OF OPERATION - ASSUME Lag ROLLUP APR 80. TOTAL PRODUCTION = 11200 SAMPLES. INCREASE IN LAB SUPPLIES. INCREASE BALL MIL CAPACITY IN PREP LABe FOR THE 14 ISLANDS LISTED IN REFERENCED TwXe A 50 METER GRID YIELDS 1053 LOCATIONS (FOR INFORMATION NV-140 LISTS 76 PROFILE PAGE 3 RUHHDNA0501 UNCLAS LOCATIONS FOR THESE 14 ISLANDS)+ REF TWX SPECIFIES PROFILE SAMPLING ONLY AND WITH 6 INCREMENTS PER PROFILE EQUALLING 6318 TOTAL SAMPLES. COMPARE THESE NUMBERS TO POSSIBLE PRODUCTION RATES RAISES THE FOL LOWING QUESOIONS: 1. WHAT PROFILE LOCATION DENSITY IS ACCEPTABLE? (IS A GRID ACCEPT—ABLE?) 2. WHAT TRADE OFFS CAN BE MADE TO REDUCE SAMPLE LOAD (E.G. REDUCE NO, OF ISLANDSr N. OF CHEMICAL ANALYSIS REQUIRED PER PROFILE)? 3. con INCREASED MANPOWER BE PROVIDED IN TIMELY MANNER (I1.EALT 2)? 4%. IS IT REASONALBE TO ASSUME LAB OPERATIONS UNTIL 1980? Se ARE ALL ORGANIZATIONS INVOLVED IN THE CLEANUP WILLING TO COMMIT THEMSELVES TO THIS NEW TASK? OTHER QUESTIONS RELATING ARE: 1. A METHOD IS NEEDED TO INTEGRATE OVER THE 10+ 15 AND 20 CM INCREMENTS SPECIFIED IN THE PROFILE? SOME OPTIONS - USE EXISTING ON@ISLAND EQUIPMENT AND TAKE A 5 CM (10 CM wIDEr 10 CM LONG) THICK SECTION FROM THE MIDDLE (TOP OR BOTTOM) OF THE LAST 3 LARGE IN@PAGE 4 RUHHDNAOS501 UNCLAS CREMENTS AND INTEGRATE OVER THE PROFILE MATHEMATICALLY OR DEVISE A METHOD OF SAMPLING THE INCREMENT INTACT WHICH INTEGRATES OVER THE ENT@RE INCREMENT MECHANICALLY. 2.e SHOULD CONSIDER SURFACE MEASUREMENT WORK OF IMP AND RELATED LAB WORK AS ESTIMATE OF SURFACE ACTIVITY FOR CS"137+ AM"241 AND PU239+ 240. COVERAGE IS BETTER THEREFORESTATISTICS OFR ACTIVITY DISTRIBUTION WOULD BE BETTER = PRELIMINARY WORK HERE INVESTIGA= TING THE CORRELATION BEOWEEN VAIOUS ISOTOPES AND SR-90 FROM NVO"-140 DATA SUGGESTS THIS METHOD MIGHT RE USED TO FILL IN DATA GAPS+ PARTICULARLY FOR SURFACE INFORMATION. FINALLY = IT IS NECESSARY TO SCOPE THE«SIZE OF THE OVERALL TASK AS ILLUSTRATED ABOVE SO THAT SUFFICIENT PLANNING CAN BE MADE TO FIT IT PRIORITY
