- Problem - In the original decay example, it was noted that the 25 km resolution concentration grid would under-estimate air concentration and deposition near the source. Recompute the close-in dose from deposition using a much finer resolution concentration grid.
- Hint -
Start with the saved configuration conc_decay_control.txt and conc_decay_setup.txt. Try a grid resolution of 1 km. Furthermore, there is no need to run the simulation beyond a duration of 6 hours. Does the sampling start time need to be adjusted?
- Solution - dose plot. How long would it take for a 1 REM total dose to be exceeded [0.00071 REM/day x 365 days = 0.26 REM]? What if the deposition rate was 1 cm/s rather than 0.1 cm/s?
