There are a lot of every day and house hold items that use radiation, and some of it you wouldnвЂ™t even expect. During this experiment, I wanted to discover what items in the classroom use radiation. My experiment was to find what everyday objects give off radioactive particles, or will respond to a Geiger counter. A Geiger counter is essential to my experiment because without it, I wouldnвЂ™t have been able to determine what objects gave off radioactive particles. EXPERIMENT To find out what every day objects contained radiation, I used something called a Geiger counter. A Geiger counter is an instrument that detects forms of ionizing radiation. Such radiation includes gamma rays and alpha and beta particles. To do this experiment you only need a few things. 1.)Geiger counter 2.)Various objects to test These are about all you need to start this experiment. Now on to the experiment; Step 1: When you get the Geiger counter, turn it to x1, unless you plan on testing objects that are dangerously high in radioactivity. Step 2: Begin to slowly move the counter rod over the object that is going to be tested. Step 3: Record the data. That is the way to conduct this experiment, and surprise yourself with the results. DATA Here are my results: Items Tested Reading On X1 Dog tags 0-.05 Pencil Lead .02-.05 Lead Isotope 2.10 .05+ Geiger Counter 0.05 Computer Screen 0.05 Key Board 0 Myself 0.05 Calculator 0.03 CD 0.04 The Air 0.05 Laptop .03-.15 Electrical Outlet .05-.075 Winter Fresh Gum 0.025 Although these objects give a reading, the amount actually given off is too little to be harmful.
