Modeling the Source Area source (uniformly distributed) 5 m height Density of heavy structural wood approximately 800kg/m 3 Area = 0.45 m 2 Plume Type Fixed Same plume rise (10m, 30m, 50m) for every stability category. 3/14/2017 2
Defining the Source 2.72*10 5 ci/yr Ra-226, T 1/2 = 1600 years 1.814*10 4 ci/yr Cs-137, T 1/2 = 30.08 years Build up time = 1 year Since minimum build up time is 1 year, source must be released over a 1 year period rather than 2 hours. Dose is calculated for 50 years after the build up time/analysis period. Daughters in chain are not included, because they would build up more over the period of one year compared to the 2 hours they are released. Confirmed that they have a negligible effect on dose when included. 3/14/2017 3

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

Dana University of Pennsylvania ‘17, Course Hero Intern

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
