Fox RT Guide vs NDT Field Calc

Fox RT Guide is the essential companion app for NDT radiography professionals. Whether you work with Film, CR (Computed Radiography), or DR (Digital Radiography) systems, this app puts critical tools and references right in your pocket — on-site and beyond. EXPOSURE CALCULATOR • Recommended mode: Enter material, thickness, and distance — get optimized kV, mA, and focal spot recommendations • Manual mode: Calculate exposure times for X-Ray and isotope sources (Ir-192, Co-60, Se-75, Tm-170) • Supports Film, CR, and DR detectors with ISO 17636-2 compliant geometric unsharpness (Ug) validation • Save and reload up to 10 calculations STANDARDS REFERENCE • Quick-access database of 15+ major NDT standards • Covers ASME, ASTM, ISO, AWS, API, and ASNT codes • Key requirements summary with direct links to official standards bodies TECHNIQUE CHARTS • Material-specific exposure parameters for Carbon Steel, Stainless Steel, and Aluminum • Charts for X-Ray, Ir-192, and Co-60 sources • Separate data for Film (ISO 17636-1), CR, and DR (ISO 17636-2) DICOM / DICONDE IMAGE VIEWER • Open DICOM and standard image files • Window/Level adjustment, zoom, pan, rotate, and flip controls • On-image measurement tool with mm/inch calibration • Full DICOM tag browser with search IQI / PENETRAMETER GUIDE • ASTM E1025 hole-type penetrameter lookup • ISO 19232-1 Wire IQI (W1–W19) reference • ISO 19232-5 Duplex Wire IQI (D1–D13) with SRb requirements SAFETY CALCULATOR • Safe distance calculations for X-Ray and isotope sources • Shielding requirements for lead, concrete, and steel • ALARA guidelines and dose rate reference ADDITIONAL TOOLS • Film Selection Guide — thickness-based film recommendations per ISO 11699-1 • Density Guide — interactive density reference with acceptance ranges • Geometric Unsharpness Calculator — Ug calculation with ISO 17636-2 quality ratings • Defect Interpretation Guide — weld, casting, forging, and processing defects with acceptance criteria per ASME, AWS, API, and ISO codes • Unit Converter — Length, Radioactivity, Dose, Pressure, Temperature, Film Density, and Distance • Detector Performance — DQE, MTF tables, calibration procedures, and Film vs CR vs DR comparison RT QUIZ • 60 questions across 6 categories for ASNT Level I, II, and III certification preparation • Categories: RT Fundamentals, Equipment & Setup, Image Quality, Standards & Codes, Safety, and Defect Interpretation • Instant feedback with detailed explanations • Score tracking with category breakdown Designed by Foxes, for NDT professionals. © 2026 Mind Fox Software Solutions Pvt Ltd

NDT Field Calc is the radiographic testing toolkit built by RT people, for RT people. Where general NDT apps skim the surface, this one goes deep on the film and radiation math you actually use in the field — and every calculation is built from ASNT and NCRP physics, not copied from a spec sheet. SEVEN TOOLS, VERIFIED PHYSICS • Film Interpretation — density accept/reject by code, the tool most apps leave out • R-Factors — quick reference table for technique selection • Source Decay — current activity for Ir-192, Co-60, Se-75, Cs-137, Yb-169 and Tm-170, with real half-lives and gamma constants • Exposure Correction — recalculate time across distance and source-activity changes • Geometric Unsharpness — Ug from source size, thickness and distance • Safe Distance — barrier/boundary distance from activity and dose rate (always confirm with a survey meter) • Pipe Schedule — wall thickness lookup to ASME B36.10M BUILT FOR THE FIELD • Works offline — no signal required at the shot location • Fast, mobile-first, dark interface that reads in bright sun or a dark bay • Made by a working radiographer, not a software shop Whether you shoot pipeline, structural or plant work, NDT Field Calc puts the numbers you trust one tap away. Radiation safety note: Safe Distance and exposure outputs are planning aids. Always verify with a calibrated survey meter and follow your radiation safety program.
