Principle

The relationship between the distance and the radiation intensity is determined with the aid of the sample by increasing the distance between the Geiger-Müller counter tube and the sample.

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 how the intensity of radiation from a radioactive source changes with increasing distance.

Learning Objectives

The students use the experiment to derive the relationship between the distance and the radiation intensity of the radioactive source.
