Shielding Calculations, Principles

Shielding Calculations, determine the “ workload ” W in your department:

TRAK

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)
