/*
Define multiple simulated workplace exposure scenarios in a single input file.   In these scenarios, a worker is exposed to the following time varying radiation field:

     MORNING SHIFT:
          2 hour exposure (low-level exposure)
        15 minute break (no radiation exposure)
          2 hour exposure (intermediate level exposure)
          1 hour lunch break (no radiation)
     AFTERNOON SHIFT:
          2 hour exposure (low-level exposure)
         15 minute break (no radiation)
           2 hour exposure (high-level exposure)

The baseline 14 Gy exposure is re-scaled so that the worker experiences total dose rates from 1E-05 Gy (1 mrad) up to 20 Gy (ok. a 20 Gy exposure would kill the worker but this is just an example). Scenarios includes a background dose rate of 2.2815E-07 Gy/h (= 200 mrad/y).
