If the DOSE is greater than 1, what is the status of the exposure?

• A. The exposure is not allowed
• B. The exposure is allowable with warning
• C. The exposure is allowed
• D. The exposure is optimal

Answer: (A)

The concept being tested is that safety thresholds set a maximum allowable dose for exposure. When the measured dose exceeds that limit, the exposure is not permissible. A dose greater than 1 signals that the exposure is beyond the regulatory or safety boundary, so immediate steps are needed to reduce the dose below the limit and to address the factors that caused the overexposure.

In this scenario, the correct status is that the exposure is not allowed. The other options would imply that over the limit is still acceptable or even ideal, which isn’t consistent with protective safety standards.
