Shielding of beta radiation with Cobra SMARTsense

Principle

The shielding of the beta rays is investigated using various materials such as aluminium and Plexiglas. The material thickness is also varied to determine the half-value thickness.

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 influence of various materials such as aluminium, Plexiglas and index cards and their shielding from beta rays.

Learning Objectives

Students recognize the influence of the material and the material thickness to shield beta rays.
