Lesson: Detecting and Blocking Different Types of Radiation Physics

Students will be able to

• recall that a Geiger counter is a device that can be used to measure the level of radiation in an area,
• recall that the number of radioactive decays per second is measured in becquerels (Bq),
• recall that ionization is the process of an atom gaining or losing electrons,
• recall what thicknesses of some common materials will block alpha, beta, and gamma radiation,
• recall the approximate range of alpha, beta, and gamma radiation in air,
• recall what materials are best for safely storing radioactive materials,
• recall the relative electric charge of alpha, beta, and gamma radiation.
