Neutron <strong>and</strong> Gamma Shielding<br />
SIMPLIFIED SHIELD THICKNESS CALCULATION<br />
perform radiation measurements to verify these calculations<br />
I = shielded exposure rate<br />
I<br />
0<br />
= unshielded exposure rate<br />
n = number of shielding layers (tenth or half)<br />
n<br />
I = I<br />
