The influence of distance on the intensity of radiation with Cobra SMARTsense

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.
