Description of options:
Field Name Description
Probability of
Detection (
σ )
This is the probability that exactly one alarm Level
of contamination will cause and alarm.
For further information, see
Description of
Parameters Used in Calculations (page 6-2) .
Note that the probability is also expressed as a
percentage in parentheses
Values: 0 to 10 sigma in 0.1 sigma steps.
Default: 1.65
σ
Probability of False
Alarm (
σ )
This value is the probability that a false alarm will
NOT be given during a measurement. This
probability is used by SAM12 to determine the
monitoring time and the Effective Alarm Level and
Minimum Detectable Activity.
For further information, see
Description of
Parameters Used in Calculations (page 6-2) .
Note that for simplicity, the Probability of False
Alarm is expressed as a percentage in parentheses.
Values: 0 to 10 sigma in 0.1 sigma steps.
Default: 3.1
σ
Minimum Monitoring
Time (s)
Note that the Minimum monitoring time must be
equal to or be less than Maximum Monitoring Time.
This is the Minimum time for which articles are
monitored. This field is used in conjunction with
the Maximum Monitoring Time.
Values: 3 to 300 s
