C. FORMULAS

The following formulas are used in various systems manufactured by TSA Systems, Ltd. They are provided to assist in verifying system operation and to give our customers a better understanding of how the systems operate

C.1. ACTIVITY FROM COUNTS

Where:

Activity = Activity in nCi

Eff = Decimal efficiency (i.e. 10% = 0.1.)

N = Net counts per second (cps – background cps)

C.2. EFFICIENCY

Where:

N = cps with source – background cps

activity = test source activity in nCi

C.3. N*SIGMA ALARM LEVEL

This formula calculates the minimum activity, in disintegrations per minute, that can be reliably detected under a given set of operational conditions.

Where:

bkg = Background counts

Sigma = 1bkg

N = N*Sigma value
