What environmental LLD Δt do other facilities use for their REMP samples? 1) elapsed time between environmental collection, or end of the sample collection period, and time of counting OR 2) the midpoint of the sample collection period and time of counting ----------- During a Review of our REMP program the following was identified: NUREGs 1301 and 1302 define the environmental LLD Δt as the elapsed time between environmental collection, or end of the sample collection period, and time of counting (see NUREG 1301/1302, Table 4.12-1, notation (3)). This is different from the Δt definition used for liquid and gaseous effluent LLDs, which is defined relative to the midpoint of the sample collection period. See NUREG 1301/1302 Table 4.11-1, notation (1) and Table 4.11-2, notation (1).
