P6 Radioactive materials - weblinks
Mindsets http://www.mindsetsonline.co.uk/ supply the SEP Geiger counter [GEI 003] which has an integral GM tube and registers events as an audible click as well as counting on an LCD display.
The Idaho State University website www.physics.isu.edu/radinf/natural.htm is a useful source of information about background radiation.
On the University of Colorado website, http://phet.colorado.edu/simulations/index.php there is a whole range of interactive simulations for teaching science, including Rutherford Scattering where students can investigate effects of changing the energy of the alpha particles, or the material of the foil.
Navigate to Simulations>Physics>Quantum phenomena>Rutherford Scattering
The Physics.org website http://www.physics.org/interact/physics-evolution/ places Rutherford’s experiment in a historical context and shows the links to other events at that time.
Another simulation of Rutherford’s experiment is available at http://micro.magnet.fsu.edu/electromag/java/rutherford/index.html
There is a copy of Rutherford’s introduction to his paper abput the scattering of alpha particles at www.math.ubc.ca/~cass/rutherford/rutherford669.html
Resources from the SEP project ‘Radiation in the environment are available on the National STEM Centre elibrary http://stem.org.uk/rx4g8
Activity AP6.6.2 A TLD badge – how it works The Health Protection agency provides a range of information about radiation topics http://www.hpa.org.uk/Topics/Radiation/UnderstandingRadiation/ including information about current dosemeters
Activity 6.6.3 Reporting on risk Resources from the SEP project ‘Radiation in the environment are available on the National STEM Centre elibrary http://stem.org.uk/rx4g8
The hyperphysics website explains how carbon-14 is produced in the atmosphere. http://hyperphysics.phy-astr.gsu.edu/hbase/nuclear/cardat.html
The University of Colorado website has an animation of radioactive decay
Activity AP6.7.1 Half life Cooknell electronics www.cooknell-electronics.co.uk supply a half life demonstration which measures the deay of thorium-232 in gas mantles.
Lascells www.lascells.com supply 10mm cubes, coloured on one face to be used to model the random nature of radioactive decay.
The Chernobyl Children’s Project website www.chernobyl-children.org.uk/ gives information about the human impact of the Chernobyl accident.
The Committee on Radioactive Waste Management website http://www.corwm.org.uk/default.aspx describes the work of the expert group which advises the UK government.
The ITER project http://www.iter.org/default.aspx is an international project which aims to show that nuclear fusion can be used as an energy source.
The JET project http://www.jet.efda.org/ was the predecessor of ITER and demonstrated some of the issues to be overcome in moving from scientific research of fusion to commercial exploitation as an energy source.
See www.astronomynotes.com/starsun/s3.htm for an animation of fusion.
The How Stuff Works – nuclear bomb provides far more information than is needed for those students who want to know more. http://people.howstuffworks.com/nuclear-bomb1.htm
The Lawrence Berkeley National Laboratory website www.lbl.gov/abc/Basic.html#Fusion places ideas about fusion in the context of stars.
