The back-scattering of beta radiation with Cobra SMARTsense

Principle

The intensity of the backscattering of β rays is investigated as a function of different materials.

Benefits

• Especially understandable and didactically prepared description of the experiment (relevance to everyday life, etc.) including protocol questions.
• Future-oriented teaching: Integration into digital science lessons with tablets or smartphones.
• Increased motivation of students by using the intuitive measureAPP.
• Increased media competence.

Tasks

The students investigate the backscattering of beta rays by detecting the scattering rate on different materials using the Geiger-Müller counter tube.

Learning Objectives

With the help of the experiment, the students determine the dependence of the intensity of the backscattering on the material used.
