Range and shielding of alpha radiation with Cobra SMARTsense

Principle

The range of α rays should be known by the shielding by means of paper, which completely absorbs the α particles and thus causes a reduction of the radiation intensity.

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 determine the range of the α rays by shielding the α particles with paper.

Learning Objectives

The aim of the experiment is to determine the range and shielding of α radiation.
