About the ASNT IRRSP Exam
The ASNT Industrial Radiography Radiation Safety Personnel (IRRSP) certification confirms that a radiographer has the radiation safety knowledge required to perform industrial radiography under 10 CFR Part 34 (and Agreement State equivalents). The 100-question, 3-hour computer-based exam at Pearson VUE covers radiation physics, dosimetry and biological effects, ALARA and shielding, exposure equipment (projector-type cameras and X-ray tubes), emergency response, NRC regulations, and DOT transport rules. A separate employer-administered practical (hands-on) exam, typically completed within 6 months of the written exam, is also required before working independently.

In Term Pairs, twelve face-down cards hide six pairs of terms; flip two at a time to find each pair, and every pair you find shows what the term means. In Term Search, five terms hide in a grid of letters, reading across, down or diagonally; drag across a term to circle it, and each term you find shows what it means.
