A material used for radiation shielding.

Fields

name: String

Name of the material (e.g. “Lead”, “Concrete”).

atomic_number: u32

Atomic number Z of the primary constituent element.

density: f64

Mass density [kg/m³].

mass_attenuation: f64

Mass attenuation coefficient μ/ρ [m²/kg] at the relevant photon energy.

neutron_cross_section: f64

Thermal neutron absorption cross-section [barn = 1e-28 m²].

Implementations

impl RadiationMaterial

pub fn new( name: impl Into<String>, atomic_number: u32, density: f64, mass_attenuation: f64, neutron_cross_section: f64, ) -> Self
