That and blast the hell out of the enemy when you 'feel' it is the
thing to do.

Again, however, the LM panels used paint containing promethium.
Promethium-147, having a half-life of only 2 1/2 years, is highly
radioactive. Unshielded at close range, the beta particles are
significant. With even minor shielding -- aluminized fabric or a thin
layer of clear acrylic -- they are not.

Thank for the info. But I am still suspicious that this 'radio
luminescene' has something to do with stopping radiation too. Why
gigantic panels when a couple of small ones would do just as well?

Since you have absolutely no honest intentions nor expertise to offer
as to anything that's topic constructive, in which case why don't you
go play with your prototype spaceplane?

Such prototypes are actually not only as small as you'd like, and thus
humanly manageable, but very doable as offering proof of their
potential capability in full scale.

Besides fully interactive 3D software that can accomplish damn near
anything, it's rather simple as to keeping your prototype GLOW down to
a dull roar in order to suit whatever the demonstration, by way of
simply limiting fuel loads and excluding payloads.

How about doing a 1/100 scale static prototype version for wind-tunnel
testing?
How about your doing a 1/10 scale flyable prototype, with 'tomcat' at
the controls?

Wasn't 13 rads per hour about what you said Astronauts would have to
deal with in Outer Space? Strange the two figures match. I wonder if
maybe Promethium changes hard radiation into soft radiation?

Quite a trick if they can do it.

No, I didn't say anything close to 13 rads/hr, at least not by way of
space travels external to the magnetosphere, whereas if the moon is not
evolved and you're headed away from our sun, it should be much less
than that amount of dosage unless your butt is getting nailed by a bad
solar/cosmic event, in which case it really doesn't matter how low the
average dosage level is because, from a singular bad event you are
either dead or soon going to become dead unless you've got one hell of
a massive spacecraft protecting your frail DNA. Having an extremely
well shielded cash of your sub-frozen bone marrow and a few of those
spare stem-cells available might save the day, whereas otherwise don't
plan upon coming home unless you're in a body-bag.

I had actually said many times that the Van Allen belt environment that
can offer an average of 23 rads/hr while shielded by 2g/cm2 (roughly
5/16" worth of 5086 aluminum) is derived from a sufficiently
hard-science matter of fact, and as such is less TBI worthy than being
situated on the gamma and hard-X-ray moon of ours while using that same
2 g/cm2 worth of shielding, and that's only recently become a matter of
scientific fact because our moon having been recorded as being much
worse off than what the well known bad parts of our Van Allen expanse
has to offer. Therefore, I wouldn't expect a moonsuit dosage of
anything less than 50 rads/hr if it's a relatively passive solar day,
and otherwise we're talking several hundreds of rads/hr if it's a
somewhat more active solar day, with a truly bad solar day offering
several thousands of rads/hr that have frequently gone entirely off
scale upon having saturated the various detection instruments we've got
situated external to our magnetosphere's Van Allen expanse. However,
if our sun goes into a nearly passive mode is also when the most lethal
dosage of cosmic influx gets through. So, if you are out and about as
moonsuit walking on that physically dark and nasty moon of ours, you
are sort of in a no-win situation, especially getting double-IR and
unavoidably gamma plus extra X-ray TBI dosage worthy by day.

While on the moon, unless you're situated within a very small diameter
but otherwise deep crater, you're unavoidably surrounded by at least a
km radius of absolutely nasty badlands, therefore count on 3.14e6 m2
worth of whatever's locally radioactive and otherwise being unavoidably
reactive to the cosmic and solar influx as being of contributing
factors to the demise of your frail DNA. Since there's supposedly such
a slight amount of surface atmosphere to work with, that's regardless
still unfortunately capable of being nicely reactive (especially
reactive if there's heavy elements such a Rn222 are available), and
thereby affording hardly any measurable attenuation of whatever is
coming off each and every square meter of that naked moon, whereas such
each m2 doesn't actually have to represent all that much individual
gamma and hard-X-ray dosage. A few local millirads/m2/hr times 3.14e6
and your DNA is going to be seriously fried from all directions, as
well as from the inside out as that local and whatever influx gamma
interacts with the bone and bone marrow of your own body. And, since
it's of an environment that's no longer representing itself as a given
point source of radiation, but that of a surrounding terrain of
radioactive and otherwise unavoidably reactive badlands, as such
there's nothing much you can do to save your soul, other than getting
the hell out of there as soon as possible or going deep underground,
because it's simply not practical much less affordable or even
technically as of yet doable to deliver a necessary amount of suitable
shield material to that moon of ours, that is without such an effort
creating yet another delivery impact crater.

Of course, if we had your efficient VTOL spaceplane with it's million
pound payload capability, as such we could obviously go to/from that
nasty sucker as often and as quickly as perhaps within 7 day round
trips, spending as little as an hour on the earthshine illuminated deck
where the local reactive environment is getting least impacted by the
solar influx. Of course, just having to nearby orbit that moon of ours
in simply not going to represent a safe margin of crew and passender
error or any measurable attenuation factor from being fully exposed to
the lunar surface that's radioactive as well as remaining unavoidably
reactive for as far as your spaceplane can see, whereas we are talking
about a 600 km or better radius, of at least 1.13e12 m2 of exposure
that the extremely large but otherwise relatively low density
spaceplane of your's has to contend with. Thus how much shield mass
and/or volume of whatever's similar to water are you planning upon
having for benefiting that of your crew and passenders, or is death
their only viable option?

BTW; one form of radiation does not stop or even attenuate that of
another form of radiation, it just makes the situation worse off from
whatever interactions are taking place. One hell of an artificial
magnetosphere might however achieve the goal of defending yourself from
the ravages of essentially DNA toxic radiation.
