ASNT Industrial Radiography Radiation Safety Practice Test

What transport index is designated for materials that are not likely to expose handlers or the public significantly?

1. White

2. Yellow II

3. Yellow III

4. Red

The correct answer is: White

The correct choice is the White transport index. This designation is applied to materials that present a very low risk of exposure to radiation and are considered safe for transport. Specifically, the White transport index indicates that the radiation levels are so low that, even at the surface, the potential exposure to handlers or the general public is minimal and does not require additional safety measures beyond standard ones. In the context of transporting radioactive materials, the White category encompasses items where the radiation emitted is negligible, providing assurance that even close proximity to such materials will not lead to significant exposure. This makes White transport indices suitable for non-hazardous materials, ensuring safety and compliance with regulations.
