Shielding Calculations, determine the “
workload
” W in your
department:
W = N x S
K
x t
•
W = workload, in air @ 1 m distance from the source(s)
per time period (week, month, year)
•
N = number of applications per time period (week,
month, year)
•
S
K
= Reference air kerma rate
•
t = time of exposure (average/application)
