NDT Nation

NDT Nation is the field reference built by RT people, for RT people: 60 verified calculators, a standards reference library and three full exam-prep banks — all working offline at the shot location. 60 CALCULATORS • RT — film density by code, R-factors, source decay, exposure correction, geometric unsharpness, boundary estimate, blow factor, wall shot selector, IQI/density check, % sensitivity, HVL attenuation, inverse-square, isotope reference, film development, pipe schedule • UT / PAUT / TOFD — wavelength, near field, beam spread, Snell's law, angle-beam path, dB/amplitude, attenuation correction, thickness by echo, temperature correction, scan calculator, DAC/TCG helper, wedge refraction, TOFD setup • MT — coil shot, prod current, yoke lift test, demagnetization check • ET — depth of penetration, fill factor, phase/impedance, limit frequency • PT / VT — dwell time and dwell grid,…
