Analyzing Cosmic and Terrestrial Radiation Levels: A Comprehensive Study
This project delves into the measurement and effects of cosmic and terrestrial radiation, exploring their sources, risks, and implications for environmental health. Utilizing GPS technology to gather accurate geographical data, the team consisting of Carrie Hawkins, Kendal Hathaway, Mandie Manning, and Tyler Merrill aims to understand how radiation levels vary across different locations in the U.S. This study employs programming techniques for data interpolation and analysis, presenting findings on radiation exposure and its environmental impact.

Cosmic radiation is high-energy gamma radiation that originates in outer space and filters through our atmosphere. Sea Level -- 26(Increases about 1/2 mrem for each additional 100 feet in elevation) Atlanta, Georgia -- 31 (1,050 feet) Denver, Colorado -- 50 (5,300 feet) Minneapolis, Minnesota -- 30 (815 feet) Salt Lake City, Utah -- 46 (4,400 feet) Cosmic Radiation(MEASURED IN MREM/YEAR)
United States (avg.) -- 26 Denver, Colorado -- 63 Nile Delta, Egypt -- 350 Paris, France -- 350 Coast of Kerala, India -- 400 McAipe, Brazil -- 2,558 Pacos De Caldas, Brazil -7,000 Terrestrial sources are naturally radioactive elements in the soil and water such as uranium, radium,and thorium. Average levels of these elements are 1 pCi/gram of soil. Terrestrial Sources(MEASURED IN MREM/YEAR)
GPS UNIT • What is it? (Geographical Positioning System) • How does it work? • How is it involved in our project?
GPS Satellite • History • when was it invented • use today
Interpolation • Definition • C++ program • Sample
Sample: f(b) - f(a) f(c) - f(a) ------------- = ------------- b - a c - a
C++ Program • cout<<"Input point you want to know(x1): "; • cin>>x1; • cout<<"Input point you want to know(x2): "; • cin>>x2; • cout<<"Input point you want to know(x1): "; • cin>>x1; • cout<<"Input point you want to know(x2): "; • cin>>x2;
C++ Program (cont.) if ((x1>=a1)&&(x2>=a2)&&(x1<=b1)&&(x2<=b2)) { w=a3-b3;//difference radiation content y=b1-a1;//run larger z=b2-a2;//rise larger m=sqrt((y*y)+(z*z));//slope larger y1=x1-a1;//run smaller z1=x2=a2;//rise smaller m1=sqrt((y1*y1)+(z1*z1));//slope smaller result=((w*m1)-(a3*m))/-m; cout<<"The result is: "<<result<<endl; }
Gathering Data • GPS unit • Average radiation content
