Source Decay Calculation
Built-in Ir-192, Se-75, and Co-60 industrial gamma sources; accurately computes source activity at any time with A = A₀×(1/2)^(t/T½)
Dose Rate & Exposure Time
Estimates dose rate and exposure time via the inverse-square law D = Γ×A/d² to plan radiographic exposures
Barricade Distance
Calculates radiation barricade distances per NRC 10 CFR 20 to quickly establish safe work boundaries
Shielding Calculation
HVL (half-value layer) and shielding thickness calculations with data for 15+ common industrial materials
Geometric Unsharpness
Evaluates geometric unsharpness (Ug) per ASME V Article 2 to verify exposure setups
Offline & 45 Languages
All calculations run locally on your device with no network required; the interface is localized in 45 languages
