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.
