The geiger counter will be used to test how much radiation is in a room. Beta and gamma ray producing samples, and a smoke detector will be used with the geiger counter. A poster showing a model of an atom will also be used. The students will use a sheet of paper, a sheet of aluminum foil, and a brick to show what type of things can be used to shield them from alpha, beta, and gamma radiation. Students are to demonstrate what type of shielding will stop each of the various radiations by using the geiger counter.
Students are to identify the three types of radiations.
Alpha, beta, and gamma radiation all come from the nucleus of the atom. Alpha being weakest can be stopped by the hand. Beta can be stopped by using aluminum foil. Gamma being the strongest can be stopped by lead or concrete. Radiation has many risks and benefits.
