National Shielding learning resources

Shielding tools and calculators

Educational planning aids for MRI, RF, secure-facility and radiation shielding questions. Explore calculations, worked examples and project-planning checklists.

MRI RF shielding calculator

Larmor frequency and below-cutoff waveguide planning.

RF shielding effectiveness

Compare material and opening limits.

TEMPEST / SCIF checklist

Identify documentation gaps without a compliance score.

SCIF cost estimator

Separate published whole-facility benchmarks.

Radiation shielding calculator

User-entered HVL arithmetic; no material or isotope recommendations.

Every tool is a preliminary educational aid. Project requirements, professional review, field conditions and acceptance criteria control real designs.
