How Much of a Radiation Dose Did the ISS Crew Just Receive??

What shielding are you assuming from the Earth's magnetic field and
from the ISS structure? The unshielded dose looks quite a bit larger
than a dental X-ray, though nowhere near fatal levels. (Also, last
time I had a dental X-ray, the technician put a lead sheet over me to
avoid giving me a whole body dose. I wouldn't expect a lot of lead
sheets on ISS, nor would they do much good at 50-100 MeV.)

The shielding is actually part of the problem, the secondary radiation
dosage (TBI includes eyes, brain and so forth) of hard x-ray class.
Somewhere I've got those shuttle exposures of test film that was
heavily sealed within roughly twice the density of what the shuttle
crew typically has to work with, though no solar flak at the time,
thus recording a mere fraction, perhaps not 1% of what those onboard
ISS had to take as of the October/November 2003 solar events.

On the topic of a radiated to death moon:
As opposing gravity-wells tend to go, this lunar/Earth one is about
the only example within the recorded universe, and China has just as
good if not a better shot at obtaining their LSE claim before our
pathetic NASA gets off their bar stool, or perhaps off their space
toilet;

BTW; I've updated one of my pages pertaining to obtaining and/or
extracting energy on location, of where others have been making a
tough go of it on Venus: http://guthvenus.tripod.com/fire-on-venus.htm

BTW No.2; Didn't you know that there's going to be all but one and
only one LSE-CM/ISS (lunar space elevator).

No, Brad. Only certain types of shielding are a problem.

No. You must have read "hard x-ray" in conjunction with the description of
some solar event, decided that sounded like a cool phrase, and now it's your
pet fear-mongering expression whether it applies to any specific situation
or not. Yes, x-rays are produced as secondary radiation when charged
particles strike a heavy atom. But in practical terms for spacecraft
building, for the normal flux or for passage through (not orbits within) the
Van Allen belts the secondary radiation is not biologically significant.

And you utterly ignored the important differences between the shuttle's
orbit and a translunar trajectory. You utterly ignored the important
differences between that dosage and that of a translunar trajectory. You
utterly ignored the important difference in the sensitivity of the film. In
other words, you utterly ignored everything that would decide whether this
was a valid comparison to a moon mission. All you could process was the
fact that some film was taken into space and came back fogged.

Now would be a good time to admit again that you're the "village idiot,"
because in terms of understanding radiation you certainly are.
