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?

Correct Answer: Option A — Radioactive I and corrosive

Hazardous materials regulations require multiple hazard labels when a package meets criteria for more than one class. A nitric acid solution possessing radioactive emission levels of 0.36 rem/hr requires both Radioactive White-I and Corrosive labels.
