Table I.3, Calculational Method, Part 1---Hourly and Annual Dose Received from Gauge 1
Step No. Description GAUGE 1
Input Data
GAUGE 1
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 (1) 2 1
3 Square of the distance (ft) from the gauge to the secretary's desk in an unrestricted area, in ft2 (8) 2 64
4 Multiply the results of Step 1 by the results of Step 2 (this is an intermediate result) 2 x 1 = 2
5 Divide the result of Step 4 by the result of Step 3 to calculate the dose received by an individual at the secretary's desk, HOURLY DOSE RECEIVED FROM GAUGE 1, in mrem in an hour. 2/64 = 0.031
6 Multiply the result of Step 5 by 24 hr/d x 365 d/yr = MAXIMUM ANNUAL DOSE RECEIVED FROM GAUGE 1, in mrem in a year. 0.031 x 24 x 365 = 0.031 x 8760 = 272
