Table 1 Evaluation equation of radiation shielding parameters for silicone rubber composites.
Parameter | Equation | Unit |
|---|---|---|
Linear attenuation coefficient (LAC) | \(\mu = \frac{ - 1}{x} ln\frac{I}{{I_{o} }}\) | 1/cm |
Mass attenuation coefficient (MAC) | μm = \(\frac{{\varvec{\mu}}}{{\varvec{\rho}}}\) | cm2/g |
Half value layer (HVL) | \(HVL = \frac{LN \left( 2 \right)}{\mu }\) | cm |
Tenth value layer (TVL) | \(TVL = \frac{{LN \left( {10} \right)}}{\mu }\) | cm |
Mean free path (MFP) | \(\lambda = \frac{1}{\mu }\) | cm |
Effective atomic number (Zeff) | Zeff = \(\frac{{\Sigma_{i } w_{i} A_{i} \left[ {\frac{\mu }{\rho }} \right]_{i} }}{{\Sigma_{i } w_{i } \frac{{A_{i} }}{{z_{i} }} \left[ {\frac{\mu }{\rho }} \right]_{i} }}\) | g |
Deviation between the MAC of experimental and theoretical data from XCOM (\(({\text{Dev \%}})\) | \({\text{Dev}} = \left( {\frac{{{\text{MAC}}_{{{\text{XCOM}}}} - {\text{MAC}}_{{{\text{EXP}}}} }}{{{\text{MAC}}_{{{\text{EXP}}}} }}} \right) \times 100\) | % |
