Medical supply final mile radioactive iii visual label recognition tool ad-free tests
Radioactive III is the yellow label showing three red vertical bars and the highest transport index of the three categories. It carries the trefoil symbol and RADIOACTIVE text, with a 7. On final-mile medical and pharmaceutical loads it signals the strongest radiation level of the labeled categories and the strictest handling.
What Radioactive III looks like
The category III label is yellow, carries the radioactive trefoil symbol (the three-bladed fan), the word RADIOACTIVE, and a 7 for Class 7. The detail that marks it as category III is three red vertical bars. Those bars are the recognition key, because both II and III are yellow.
Read the bars
The number of red vertical bars rises with the radiation level the package emits. Category I has one bar on a white label, category II has two bars on yellow, and category III has three bars on yellow. So when you see yellow with three bars, you are looking at the highest of the three categories, which also carries the highest transport index.
The three categories
The recognition map for Class 7 labels:
| Category | Background | Red bars | Level |
|---|---|---|---|
| Radioactive I | White | One | Lowest |
| Radioactive II | Yellow | Two | Moderate |
| Radioactive III | Yellow | Three | Highest of the three |
Three bars on yellow is category III, the highest. Always follow the official requirements.
Why medical loads carry it
Final-mile medical and pharmaceutical deliveries can include radioactive materials such as diagnostic or treatment isotopes, which is why drivers on those routes meet the radioactive labels. Recognizing category III tells you the package emits the strongest measurable radiation of the labeled categories and is handled most strictly, even if the package is small.
Placard versus label, and verifying
Note that the I, II, and III categories live on the package label, shown by the bars and the transport index, while the vehicle uses the yellow-over-white RADIOACTIVE placard with the trefoil and a 7. Radioactive transport is tightly regulated, so confirm the exact handling, labeling, and placarding requirements in the official materials and with your authority.
Frequently asked questions
- How do I recognize a Radioactive III label?
- It is yellow with three red vertical bars, the trefoil symbol, RADIOACTIVE text, and a 7. Three bars on yellow marks category III, the highest of the three categories. Confirm in your official materials.
- What do the bars on a radioactive label mean?
- They show the category: one bar (white) is I, two bars (yellow) is II, three bars (yellow) is III. More bars means more radiation and a higher transport index.
- Is the category on the placard or the label?
- On the package label. The vehicle placard is the yellow-over-white RADIOACTIVE diamond with the trefoil and a 7; the I, II, III categories appear on the labels.
