Ionising Radiation

Over the age of 16, students can work with certain radioactive sources, provided they are carefully supervised. One of your...

Teaching Guidance 16-19

Class practical: the Taylor diffusion cloud chamber is a simple piece of equipment which will clearly show alpha particle...

Practical Activity 14-16

Demonstration: displays of cloud chamber photographs are very worthwhile as a focus for discussion. As well as the straight...

Practical Activity 14-16

Demonstration: this is useful to help students understand the shape of the tracks when an alpha particle collides with the...

Practical Activity 14-16

Demonstration: this is a useful demonstration to introduce students to what they can expect to see in the diffusion cloud...

Practical Activity 14-16

Demonstration: this demonstration shows that ions can act as condensation nuclei in a supersaturated vapour. This idea is used...

Practical Activity 14-16

Demonstration: This shows the principle of cooled, supersaturated air producing clouds. It is more directly relevant to the...

Practical Activity 14-16

Demonstration: this ‘match counter’ is a useful step towards understanding a Geiger-Müller tube.

Practical Activity 14-16

Demonstration: an EHT supply can be used to produce sparks, which can be increased if you add a capacitor in parallel with the...

Practical Activity 14-16

Demonstration: this demonstration shows how a circuit can be set up to detect a familiar event that produces ions. A simple...

Practical Activity 14-16

Demonstration: this is a general introduction to the Geiger-Müller (G-M) tube describing and explaining the basic principles...

Practical Activity 14-16

Demonstration: the spark counter is a highly visible (and audible) way of showing and counting ionisation of the air caused by...
