Design a simulation to determine radiation footprint in HRRL cell.
1.) The ceiling is 4 feet thick
2.) there is PB shiedling between the HRRL accelerator room and the accelerator operator station
3.) the dirt is about 10 feet thick on the wall side where the accelerator is going to be mounted
4.) determine shielding wall thickness for HRRL cavity to reduce dose out the door
5.) Determine shielding for Tungsten converter

Material Definitions
Concrete
Concrete has 6 elements and a density of 2.7 g/cm^3
| Element | Atomic Weight (A) | Atomic Number (Z) | Proportion by Weight |
| 1 | 1.0079 | 1. | 0.004 |
| 2 | 15.9994 | 8. | 0.509 |
| 3 | 26.981539 | 13 | 0.034 |
| 4 | 28.0855 | 14. | 0.345 |
| 5 | 40.078 | 20 | 0.070 |
| 6 | 55.8474 | 28. | 0.038 |
Relative Rates
The first step in the simulation will be to compare relative radiation rates at the exit of the accelerator room. The radiation exiting the accelerator room before and after moving the accelerator will be simulated. Although all particles can be tracked we will mostly be interested in gamma and neutron fluxes through the door. The ratio of before/after moving fluxes for gamma and neutron should be plotted as a function of energy.
