Radiation Lab Report

Objective-We are trying to figure out two things while doing this experiment. First thing is how strong is the radiation based on the distance from the source and if thickness of the material effects how much radiation gets through.

Introduction-One thing to know about this experiment is Isotopes.Isotopes of an element are different versions with same number of neutrons but different number of neutrons. Also these isotopes can be unstable which means they decay overtime releasing radiation. Radiation is the what we are going to look at while doing the experiment.

Safety Precautions- We did this experiment as one whole group which help prevent accidents. Even though we performed this experiment as one group we had to make sure that we were safe. We had to make sure we used the …show more content…
Something that we did to avoid making errors was to make sure we used the Geiger Counter correctly. We made sure to wait for a minute in order to get the CPM. Also when the materials were placed in the Geiger Counter that they were all in the same layer. Last thing that helped was making sure that our graphs were labeled correctly so that when we put the information it would sure the correct correlation of how radiation is effected based on distance and thickness.

Conclusion- We tried to find out how distance affected radiation and how the thickness of the object would affect how much radiation would get through. Based on the graphs and the data we concluded that the further away something is less radiation it would be exposed too. Also the thicker the object is the more resistant it is against radiation not allowing it to go trough.We saw that lead was the most thick which meant it was the best material against radiation while Polyethylene was the
