Irene Schneider Reporting
Radiation Report:
Code = BLUE
Loc = Hellas Basin bottom
Avg Atmos Col dens = 22 gr/cm2
Composition = std back
Out Hab = 0.083 rem/day = 0.0034rem/hr = 5.6e-05 = 0.00005rem/min.
Rad Events = None
Tot.crew.exp: EVA-10 = Whole crew went on EVA. time in EVA = 20 minutes
Tot. exposure = 0.001 rem
Tot.crew.exp: EVA-11 = whole crew went on EVA. time in EVA = 35 minutes.
Tot. exposure = 0.002rem.
Science Experiments:
Biology: none.
Geology: none.
Astronomy: will be attempted weather permitting.
Medicine: none.
Notation:
Code = BLUE: standard radiation levels.
Code = GREEN: warning for slightly increased rad levels.
Code = RED: solar storm possible onset.
Loc = location on Mars.
Composition = composition of radiation fields.
Std.Back = Standard background = GCRs. (Galactic Cosmic Rays)
Avg Atmos Col dens = Average Atmospheric Column Density. (units of gr/cm2)
Out.Hab = radiation levels monitored outside hab. (Units of dose equivalent= rem/day).
Events = solar events.
Tot.crew.exp = total crew radiation exposure when outside hab on EVA.
