Good point! Nuance is completely lost in these things.
OTOH, the exposure isn’t all that different in LEO, as I’ve been learning since we started getting ISS-RAD data. The geomagnetic field is protective, but in terms of dose, the SAA passes more or less undo the protection. So the difference
is mostly that the LEO spectrum is more populated at low-LET than deep space, which is an even greater degree of nuance.

Hi Cary,
One issue is that the press picked up on this and said that all the prior studies showing that space radiation is a problem is now called into question. So there’s a bit of damage control for those who didn’t understand the nuances
between LEO and deep space exposure.

Thanks for the links – I’m glad they did this, even with all the caveats about sample size, etc.
