Subtopics

Read nuclear notation and classify isotope relationships.

Conserve nucleon number and charge in nuclear decay.

Classify alpha, beta and gamma properties without treating penetration as the only risk.

Read exponential decay and subtract background count rates.

Calculate ages under stated closed-system assumptions and compare remaining activity.

Identify reactor component functions and calculate fission energy from mass difference.

Balance fusion reactions and calculate released energy under supplied assumptions.
