IP-2 packaging must meet IP-1 criteria and also which additional requirements?

• A. Prevent loss or dispersal of contents
• B. Prevent loss or dispersal of contents and more than a 20% increase in the maximum external dose rate
• C. Must withstand a drop test
• D. Must be able to float in water

Answer: (B)

The key idea is that IP-2 packaging adds a safety requirement beyond the basic IP-1 containment. It must keep the contents contained (no loss or dispersal) and also limit any increase in the external dose rate to a safe level. In other words, IP-2 not only protects the package from leaks but also ensures that shielding and containment keep radiation exposure of people handling the packaging within a small, acceptable limit—typically not exceeding a 20% rise in the maximum external dose rate. The other options miss either the containment-dose rate combination or bring in unrelated tests (like a drop test or buoyancy), which aren’t the extra criteria that define IP-2.
