Ideal for secondary schools and colleges, this apparatus helps students explore the inverse square law in physics, making it easier to understand the relationship between gamma radiation intensity and distance. Designed for practical classroom demonstrations, it supports hands-on learning in radiation experiments.

• Includes a wooden track with dual ruled scales for accurate distance measurement

• Comes with a source holder compatible with 4mm mounted sources

• Suitable for use with a Geiger-Muller tube (B8A49724), holder (PP00057038) and counter (PP00059838), and radioactive sources, not included

• Supports practical investigations into gamma radiation and the inverse square law

• Designed for secondary and post-16 science teaching
