Question 1 · 1 mark · Difficulty 1/3

A student in Trinidad is investigating radiation using a Geiger-Müller tube. She records 25 counts per minute with no source present. What does this reading represent?

  1. Experimental error
  2. Background radiation
  3. Contamination of the detector
  4. Faulty equipment
Show answer & explanation
✓ Answer: BBackground radiation
Award 1 mark for identifying background radiation. Background radiation is always present from natural sources such as cosmic rays, rocks, and radon gas. A is incorrect — this is not an error but a real measurement. C is incorrect — contamination would give higher, inconsistent readings. D is incorrect — this is normal detector behaviour.
Question 2 · 1 mark · Difficulty 2/3

A technician at a bauxite processing plant in Jamaica uses a radiation source to check the thickness of aluminium sheets. Which type of nuclear radiation would be MOST suitable for this purpose?

  1. Alpha particles
  2. Beta particles
  3. Gamma rays
  4. X-rays
Show answer & explanation
✓ Answer: BBeta particles
Award 1 mark for identifying beta particles as suitable for thickness monitoring of thin metal sheets. A is incorrect — alpha particles would be completely absorbed by the metal and not penetrate through. C is incorrect — gamma rays are too penetrating and would pass through without significant absorption changes. D is incorrect — X-rays are not a type of nuclear radiation as they originate from electron transitions, not the nucleus.

CXC CSEC Physics: Properties and Detection of Nuclear Radiation FAQ

How many CXC CSEC Physics questions on Properties and Detection of Nuclear Radiation are there on Kramizo?
Kramizo currently has 20 exam-board-aligned practice questions on Properties and Detection of Nuclear Radiation for CXC CSEC Physics, with new questions added every week. Each question gives you instant feedback and a full examiner-style mark scheme that tells you exactly what would earn marks on a real CXC paper. The questions span the full difficulty range — from straightforward recall (level 1) right up to multi-step reasoning and evaluation (level 3) — so the bank works for first-pass revision and final exam-week stress testing alike.
Is Kramizo free for CXC CSEC students preparing for Physics?
Yes — completely free. Every student gets 45 questions a day on the free plan, with no card required and no trial countdown. That free quota works across every subject and every topic in our bank, so you can mix Properties and Detection of Nuclear Radiation practice with other Physics topics or even switch to a totally different CXC subject without paying anything. Kramizo's optional Pro plan removes the daily cap and adds detailed progress analytics, but the free tier is the real product — used by thousands of GCSE, IGCSE and CSEC students.
Are the Properties and Detection of Nuclear Radiation questions aligned to the official CXC CSEC Physics syllabus?
Every question is written against the published CXC CSEC Physics specification, including the exact command words (state, describe, explain, calculate, evaluate, etc.), mark allocations, and difficulty tier you'd see on a real CXC paper. Explanations are written in the style of official examiner mark schemes — they tell you what is being awarded marks and why distractors are wrong, not just whether you got it right. The bank is continually refined to match the latest syllabus updates from CXC.
How is Properties and Detection of Nuclear Radiation typically tested on CXC CSEC Physics papers?
Properties and Detection of Nuclear Radiation appears across multiple question types on real CXC CSEC Physics papers — most commonly as multiple-choice questions in the objective section, structured short-answer questions in the main paper, and occasionally as part of an extended response. Kramizo's practice bank reflects that mix: 4-option MCQs, true/false statements, fill-in-the-blank key terms, multi-select questions, and ordering questions. Working through the bank gives you exposure to every question style examiners actually use.
