Propolis Cognitive Error Autopsy

Official Correct Choice:
Option A: 10


Concept:

The Becquerel (Bq) is the base SI unit of radioactive activity.

Solution:

  • By standard definition, 1 Becquerel equals exactly 1 nuclear disintegration (decay) per second.


  • Because there is a direct 1:1 ratio between the unit and the physical event, 10 Becquerels simply equates to exactly 10 decays per second.


Why other options are incorrect:

These options incorrectly assume that there is a complex conversion factor, scaling by powers of 10, which is unnecessary for Becquerels.

Quality & Fidelity Assurance: Every question on BeambePrep is rigorously curated against the official PMDC syllabus with zero filler, zero out-of-syllabus content, and zero typos. When an authentic past paper originally contained a historical mistake or ambiguity from the examining board (such as UHS or NUMS), BeambePrep faithfully reflects the original paper while detailing the nuance and scientific consensus in the autopsy above.
