Table I.5, Calculational Method, Part 1---Hourly and Annual Dose Received from Gauge 3
Step No. Description GAUGE 3
Input Data
GAUGE 3
Results
1 Dose received in an hour at known distance from gauge (e.g., from manufacturer's data), in mrem/hr 2 2
2 Square of the distance (ft) at which the Step 1 rate was measured, in ft2 (3) 2 9
3 Square of the distance (ft) from the gauge to the secretary's desk in an unrestricted area, in ft2 (15) 2 225
4 Multiply the results of Step 1 by the results of

Step 2 (this is an intermediate result)

2 x 9 =18
5 Divide the result of Step 4 by the result of Step 3 to calculate dose received by an individual at the secretary's desk, HOURLY DOSE RECEIVED FROM GAUGE 3, in mrem in an hour 18/225 = 0.08
6 Multiply the result of Step 5 by 24 hr/d x 365 d/yr = MAXIMUM ANNUAL DOSE RECEIVED FROM GAUGE 3, in mrem in a year 0.08 x 24 x 365 = 0.08 x 8760 = 701
