ASNT Industrial Radiography Safety Test 2026 – Complete Exam Preparation

The correct label for a shipping container surveyed at 3 mR/h at a distance of 39.37 inches falls under the category of Yellow II. This classification is based on the radiation levels and the associated regulatory requirements for labeling and transport of materials that emit ionizing radiation.

In this scenario, "Yellow II" is appropriate because it signifies that the radiation level exceeds the limits set for a "White" label but does not reach the thresholds necessary for a "Yellow III" label. Specifically, a Yellow II label is used for packages where the radiation level is greater than 0.5 mR/h but less than or equal to 50 mR/h at a distance of 1 meter. A survey result of 3 mR/h at a distance of 39.37 inches (which is essentially 1 meter) indicates that this container is safely within the ranges allowed for a Yellow II label.

The label communicates to handlers and transporters that there is a radiological hazard associated with the container, prompting proper precautions during handling and transport. It also meets regulatory compliance requirements set forth by regulatory bodies like the U.S. Nuclear Regulatory Commission (NRC) or the International Atomic Energy Agency (IAEA), ensuring that individuals are informed of
