A package contains nitric acid solution and is radioactive. The radiation level at the package surface is .36 millirems per hour. How should this package be labeled?
• Classification of radioactive labels (Radioactive I, II, III) based on surface radiation levels in millirems per hour • Primary hazard class of nitric acid solution under dangerous goods regulations • Difference between fissile material and ordinary radioactive material
• Compare the stated radiation level (0.36 mrem/hr at the surface) with the limits that separate Radioactive I from Radioactive II packages. • Decide what the main hazard of nitric acid solution is: does it primarily behave as a corrosive, a poison, or something else? • Ask yourself whether the package description mentions any special fissile characteristics (like enriched uranium or plutonium), or just a radioactive substance.
• Verify which radioactive label category applies when surface radiation is well below 0.5 millirems/hour versus higher values. • Confirm the UN hazard class for nitric acid solution (is it classified as corrosive, poison, or oxidizer as a primary hazard?). • Ensure that fissile labeling is only applied when the contents are specifically fissile materials, not just any radioactive package.
