How to define ACCEPTABLE detection capability ?

["chichang_RMC" <chichang@trmc.aec.gov.tw>]

Dear radsafer,



Could anyone tell me the reason that the LLD levels on TABLE 3 of REG. GUIDE

4.8

are "ACCEPTABLE" minimum criteria for objectives for instrumentation and

analytical

procedure selection for environmental samples ? Dose these levels derive

from dose

limits ?



Is there any other countries setting similar criteria ? How to define

ACCEPTABLE?



All the references (like HASL 300, ...) I can find are the definition of LLD

or MDC for

specific system but not explaining the reason for setting these minimum

capacities. Any

information relates to this topic is appreciated. Thank you !
