In a radiation incident, how many mR/hour should the staging area be exposed?

• A. not more than 2mR/hr
• B. not more than 5mR/hr
• C. not more than 10mR/hr
• D. not more than 20mR/hr

Answer: (A)

The main idea is to protect responders by keeping the staging area’s external radiation level low so work can be done safely without rapid dose buildup. Keeping the dose rate at or below 2 mR per hour provides a practical, conservative limit that supports ALARA (as low as reasonably achievable) during ongoing operations. This limit helps ensure that personnel can work in shifts, rotate in and out, and perform decontamination and logistics tasks without quickly accumulating large doses, while still staying close enough to the incident to coordinate effectively.

If the staging area’s dose rate were higher, exposure would accumulate more quickly, making it harder to stay within occupational limits over a shift and increasing the complexity of dose management and decontamination.
