Properties of Material eXplorer · v3.0

ProMatX

Calculate attenuation coefficients and shielding parameters for any material composition — standard, energy-grid, or isotope-specific.

RADIATION SHIELDING CALCULATOR

Any Composition

Enter complex chemical formulae on a mole basis — from pure elements to multi-compound mixtures like 0.1B₂O₃+0.1PbO.

Isotope Sources

Select from 9 radioactive isotopes — Am-241, Cs-137, Co-60, Eu-152, Ba-133, Na-22, I-131, Cd-109, Fe-55 — for source-specific analysis.

Batch + History

Input multiple thickness and depth values space-separated. Every calculation is saved to your profile for one-click reuse.

Shielding Parameter Evaluator

Complete all sections, then choose your output parameters.

1
Input Parameters

Prefix each compound with its mole fraction, separate with +.   e.g. Pb · H2O · 0.1B2O3+0.1PbO · 0.5Fe2O3+0.5SiO2

2
Energy Mode
3
Isotope Sources (select one or more)

Select radioactive sources to evaluate material attenuation at isotope-specific gamma energies. Leave all unselected to skip.

3
Material Density
g/cm³
g / cm³
4
Thickness & Penetration Depths

Space-separated values. Each = one sample thickness in cm.

Space-separated mean-free-path values for build-up factor calculation.
