Radioisotope: Activity: Decay time:
Shielding material: Room height: m Room width: m
Floor thickness: cm   Wall thickness: cm
Source in C3:  d1: m s1: m

Exposure in mSv/h

A1 A2 A3 A4 A5
B1 B2 B3 B4 B5
C1 C2 C3 C4 C5
D1 D2 D3 D4 D5
E1 E2 E3 E4 E5

Exposure is done at the floor, in the center of each room and in the same source's vertical plane .

1- Point isotropic source was considered.
2- Build-up factors for gamma energies over 500 keV were calculated using Taylor's equation.
3- Build-up factors for gamma energies between 100 keV and 500 keV were calculated using Trubey's table.
