All Source Total Equivalent Dose Estimate refers to the total effective dose equivalent from all sources for the monitoring period indicated. Which option is correct?

All Source Total Equivalent Dose Estimate refers to the total effective dose equivalent from all sources for the monitoring period indicated. Which option is correct?

• A. From a single source.
• B. From all sources for the monitoring period indicated.
• C. From external sources only.
• D. From internal sources only.

Answer: (B)

All Source Total Equivalent Dose Estimate represents the total dose to the body from every radiation source over the defined monitoring period. It combines external exposure (from sources outside the body) and internal exposure (from radionuclides taken into the body through inhalation, ingestion, or other incorporation) for all sources present during that period. Because it accounts for both external and internal exposures across all sources, it cannot be limited to a single source or to external or internal exposure alone. The monitoring period (often annual) defines the timeframe for this total.
