Procedure Section Throughout Step 4.2.15 (Note)
Step 4.4 Step 4.4.1 Step 4.4.1 Step 4.4.4 Step 4.4.5 Changes and Reason Added reference to Ludlum 3 frisker. The Ludlum 3 will replace the Eberline E-120 as they age beyond repair. The vendor no longer supports the E-120.
Changed minimum air sample volume from 12 ft3 to 60 ft3 to meet detection limit requirements Changed title to specify a GM probe versus the SAM-Il with a RD-22 Set background criteria for using a pancake probe. Deleted reference to SAM-Il Deleted the step. The SAM-Il instrument is no longer required for E-Plan SAM-Il with RD22 changed to pancake GM probe Denominator factor changed from 54,970 cpm to 2,749 cpm to account for the smaller efficiency of the pancake probe versus the SAM-Il. The pancake probe is 5% as efficient for iodine Reference to the SAM-Il deleted. Removed "YF" factor from the equation as it applied only to the SAM-Il Added maximum allowed background for the RM-14/L-177/E-120/Ludlum 3 as 1000 cpm MDC changed to LLD. MDC formula changed to LLD formula Changed minimum air sample volume from 12 ft3 to 60 ft3 to meet detection limit requirements Added MDCR equation Added reference to Ludlum 3 as being equivalent to the E-120 References to SAM-Il deleted and replaced with GM pancake probe Added picture showing the location of the thyroid EM-210OA Rev. 9 Page 16 of 16
