5.4.138 - Nuclear radiation properties

Understand the relationships between the nature, penetration, ionising ability and range in different materials of nuclear radiations (alpha, beta and gamma).

Use - nuclear radiation properties to connect the rule to the data and decision in the question.

This matters because - nuclear radiation properties determines what can be inferred or chosen; begin with the stated conditions and keep the conclusion tied to the evidence.

Example: apply - nuclear radiation properties to one small, clearly defined case, show the key step or comparison, and explain the result in words.

Boundary: - Nuclear radiation properties is not a universal recommendation. Check the syllabus scope, assumptions, units and the limits of the evidence before generalising.
