INTRODUCTION
Radiation is around in our every day life, whether we know about it
or not. There are a lot of every day and house hold items that use
radiation, and some of it you wouldn’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
wouldn’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.
