Assignment ID: FG133082426

Unit 7 Principles and Applications of Physics – BTEC Level 3 International in Applied Science

Assignment – Dangerous but useful – ionising radiation

Learning aim 1: Investigate the properties and uses of radioactivity

Vocational Scenario: You have been appointed as a supporting technician in the science department of a large school that delivers a wide range of subjects to sixth form learners. The centre is well resourced and has recently taken stock of a set of radioactive elements. The head of the science department has asked that you assist in the delivery of a physics lesson to Level 3 learners, to help provide additional knowledge and practical expertise to enable factual information to be given at each stage of the lesson. Many learners may be inspired by your help and guidance and may consider studying related science subjects at college or pursue job opportunities in related areas. To provide the best possible support to the Tutor and Learners, you will need to prepare notes and examples.

Assessment Task: Produce a detailed report on the main aspects of the periodic table with particular focus on atomic structure and related forces. This work should include:
• A description of particles in the atom and reference to Geiger and Marsden’s experiments.
• An explanation of radioactive isotopes using atomic number & mass
• An explanation of the relative properties of alpha, beta and gamma radiation, including the effect of magnetic fields on the types of radiation.
• An explanation of nuclear forces and stability of the atoms, including the decay process

Carry out and record a practical demonstration illustrating radioactive decay and half-life. You will need to Explain the differences of alpha, beta and gamma radiations and also the principles of nuclear fission.

Evaluate the method of detecting radiations, its effect on human and animal health and background radiation from human and natural sources.

Analyse a detailed account as a case study of well-known nuclear accidents. This should focus on:
o Specific times, dates and locations
o Known causes of the accident
o Deaths and injuries involved
o Immediate and long term damage to the environment

Explain how nuclear power stations generate electricity. You will need to include:
• A description of the uranium 235 atom and diagram of the nuclear fission process
• How the processes are contained
• A brief outline of the production of Plutonium

Evaluate the benefits of radioactive sources in science and in medicine. This should include a brief outline of uses of radioactivity in:
• Gamma and X-ray radiography for medicine and industry
• Radioactive tracers for medicine and industry
• Radiocarbon and radioisotope dating in science

Criteria: Evaluate the uses of radioactivity in terms of benefits and risks
Explain the structure of atoms and forces involved
Explain the essential aspects of ionising radiations
Explain the main applications of ionising radiations
Outline the structure of the atom, the periodic table and forces involved
Describe the essential aspects of ionising radiations
Describe the main applications of ionising radiations
