Space radiation and tourism beyond LEO

I got an account on SPENVIS at http://www.spenvis.oma.be/spenvis/
and have generated some radiation shielding data and graphs.

You tell it what orbit apogee and perigee you want, how many orbits,
what thicknesses of shielding, etc. and you get some data.  It is
very easy to use.

I generated data for a single geo transfer orbit to simulate a tourist 
going to a GEO hotel and then back.  This is through the Van Allen Belts
each way and so a lot of radiation.

I also generated data for a year stay in a GEO hotel.

So far my graphs are just for Van Allen Belt radiation and not
cosmic radiation or solar particle events.  

The graphs can be seen toward the end of:
