Whenever the sample size in neutron activation analysis cannot be made small enough, self-shielding effects need to be taken into account. When several resonance absorbers are present in the sample, resonance interference must also be considered. Est

Modern Monte–Carlo codes (e.g. MCNP) allow calculation of the power density distribution in 3D geometry assuming detailed geometry without unit-cell homogenization. The power density distribution (and its maximum value—the peaking) can be calcula
