[ RadSafe ] Comparison of a Measured Result to the Critical/Decision Level

Question for the group

When comparing a measured result to the critical/decision level, should the error (2-sigma) associated with the measured result be added to the measured result prior to comparison?  For example:
(all values in dpm and were fabricated)
MDA: 0.30
Lc: 0.16
Result: 0.10
2-Sigma Error: +- 0.07

Should the error be added to the result prior to comparison to the critical level?

Thank you,

Randy Redmond
