P2: Review

Station 1: Radiation Behaviour• emit: gives off source• reflect: bounce back journey• transmit: pass through journey• absorb: takes energy detection

• 4 effects of radiation absorption1. electric patterns2. heating (intensity/duration)3. chemical change4. ionisation

• 3 journey models: ray, wave, photon

• intensity: energy arrives each second1. number of photons2. energy of each photon3. distance

• Jan 2009: 8 June 2007: 3

Guide 1

• Connect all these ideas to the original 4 behaviours.

• Use numerous examples and diagrams.



Station 2: Cancer

• Ionisation– radiation knocks an electron off an atom, making an ion– ions are unstable and take part in other chemical

reactions– health effects of radiation (p.68)

• Ionising Radiation: UV, X, Gamma• Non-Ionising Radiation: Radio, Microwave,

Infrared, Visible Light

Guide 2

• Use diagrams to show the processes of ionisation and cancer growth.

• cancer: ionisation, mutation, multiplication



Station 3: Risks• perceived / actual risks • precautionary principle/ ALARA

• factor/outcome• Reducing risk examples:

1. microwaves2. X-rays3. Global Warming

• Jan 2009: 3, June 2008: 3, Jan 2008: 5, June 2007: 1

correlation mechanism cause

X-rays & Cancer ionising radiation X-rays cause cancer

carbon dioxide & climate change

greenhouse effect carbon dioxide levels cause global warming

Guide 3

• Use lots of examples and a concept map to illustrate these ideas.



Station 4: Ozone Layer

• ozone v oxygen– Which is better at absorbing UV radiation?– What’s the difference?– What are CFCs? Where do they come from? What

do they do to ozone?

Guide 4

• Connect this idea to global warming and compare it to the greenhouse effect.



Station 5: Greenhouse Effect

• keywords: source, emit, reflect, transmit, absorb, ultraviolet, infrared, radiation, greenhouse gases, carbon dioxide, methane, water vapour, correlation, ocean conveyor belt

• evidence• risks: ice caps melting, flooding, ice age

• Jan 2009: 7 June 2007: 2

P3 Review

Station 1: Radioactivity• background radiation

• radon case study (p.68-70)– German miners: ‘consumption’– define: radiation, ionisation– 2 reasons the miners were at risk– dose measured in mSv– no safe dose– alpha radiation– homes adapted/unadapted: ALARA

– Jun 2008: 6– Jan 2008: 3– Jun 2007: 4

Guide 1

• Use this case study to introduce the topic of radioactivity.

• Focus on definitions, mSv and minimising risks.

• Make connections.



Station 2: Types of Radiation• Alpha

– a loss of two protons and two neutrons– very large, positively charged– stopped by air, paper and dead skin cells

• Beta– one neutron becomes an electron and a proton– small, negatively charged– stopped by aluminium

• Gamma– energy, no mass, no charge– stopped by lead

• range in air, ionising power, dose factor• most dangerous inside/outside the body• badge

Guide 2

• Draw diagrams and a concept map to compare the three types of radiation.



Station 3: Changes in the Nucleus• atomic number = protons = name = symbol

• isotopes = neutrons and atomic mass can change

• atomic mass = protons + neutrons

• alpha decay loss of 2 protons and 2 neutrons– atomic number down by 2– atomic mass down by 4

• beta decay 1 neutron becomes 1 proton– atomic number up by 1– atomic mass stays same

– Jan 2009: 9– Jan 2008: 7

Guide 3

• Show an element how it is drawn on the table show the atomic mass and number.

• Use a concept map to show all the connections with protons (the most important) at the centre.

• Complete two examples for alpha and beta decay showing the changes. (ie. U-238, Bi-212)

summary, diagrams

turbine, generator• Sankey Diagrams• For/ Against Nuclear Energy– fossil, renewable or nuclear

– Jan 2009: 1– Jun 2008: 5– Jun 2007: 5
