ALPHA RANGE TEST case: air gap change produces evidence from ionisation density. Which option best answers the objective "Required practical 12: investigate the inverse-square law for gamma radiation." for Alpha, beta and gamma radiation, while reaching the conclusion about short penetration?.
- A.nuc-135-alpha-range-test: Link air gap change to ionisation density and conclude short penetration for Alpha, beta and gamma radiation.
- B.nuc-135-alpha-range-test: Ignore ionisation density and answer with an unrelated Radioactivity recall phrase.
- C.nuc-135-alpha-range-test: Swap the required nuclear distinction and claim short penetration without evidence.
- D.nuc-135-alpha-range-test: Use a calculation label only, without applying required practical 12: investigate the inverse-square law for gamma radiation..
Model answer
What a good answer should say
- The correct option is nuc-135-alpha-range-test: Link air gap change to ionisation density and conclude short penetration for Alpha, beta and gamma radiation.
Explanation
Why this works
It is correct because the alpha range test context uses ionisation density to support required practical 12: investigate the inverse-square law for gamma radiation. in Alpha, beta and gamma radiation.
The distractors fail because they either ignore the evidence, swap a nuclear concept boundary, or give a label without the required A-Level Physics reasoning.
