This set enables a comprehensive range of experimental investigations into the characteristics and properties of radioactive emission to be carried out.

The kit consists of the following items:

• Radioactivity bench
• Aluminium Absorbers
• Lead Absorbers
• Set of Solid Blocks (made of Polystyrene, Wood, Aluminium Lead)
• Source Holders x 2, with Bulldog Clips for holding a cup source
• Carriages for Source Holders ahd Absorber Plates
• Collimator
• Full teacher notes

This experimental set will enable students to investigate the following:

1. To classify radioactive and non-radioactive solids.
2. To investigate the randomness of the radiation emitted by a Radium226 source.
3. To compare the activity of emitters.
4. To reduce the intensity of radiation emitted by a source.
5. To separate the radiation emitted by a Radium226 source.
6. To investigate the rate of decay of a radioactive source and to determine the half-life of that decay process.
7. To determine the range of alpha particles in the air.
8. To investigate the absorption of beta particles in a metal.
9. To investigate the attenuation of gamma rays in lead.
10. To investigate the relationship between the intensity of gamma rays at a point and the distance of that point from the source.
11. To monitor the distribution in space of the emission from a radiation source.
12. To investigate the deflection of a stream of beta particles in a magnetic field.
13. To investigate the back scattering of beta radiation by solids.
14. To gauge the thickness of aluminium foil by the transmission of beta particles.
15. To gauge the level of a liquid or powder by the transmission of beta particles.
