Vacc Suit Use

[BP]

MGT covers many of the aspects posted here directly...

Vacc Suits start at TL-8 along with Hostile Environment Vacc Suits, with comments that 'they quickly shrink as technology advances'; provide 'protection from the extremes of..radiation'; 'are armoured and self-repairing on a small scale'; and, at TL-14 'feel like ordinary clothing with flexible hood and face mask'. (Core pg 87-88)

If one has a 3I setting, starships commonly start at TL-12. Vacc suits at TL-13 can support Advanced Computer Weave of Computer/2 - sufficient to run Intelligent Interface and Expert-1 (Vacc Suit-0). Add a TL-12+ computer instead (or in conjunction with) and Expert-2+ could be achieved.

Also, if anything hits the bubble... piece of a ship, micrometeorite like we see in all those SyFy movies... well that bubble won't hold.

Hm, forgetting the SciFi of Traveller, arn't we.

With some of the material today, and if you are willing to spend the money, sure you will not survive an impact but the other things that BP mention are possible.

So, it kind of comes down to this, do you want to die in the ship or take your chances in a survival bubble?

Secondly, a paranoid character with out their own Vacc Suit during travel might want to check on the quality of those rescue bubbles. Or buy their own personal one that is top of the line.

The main problem would probably be the radiation, because there is
still no known material that is lightweight and flexible and protects
against "hard" radiation (gamma, x-ray ...) - and I somewhat doubt
that such a material would be possible at all, because to me it seems
that the possible protection depends on the density = weight of the
material (which is why the real world uses lead).

IMTU, the ships crew is responsible for the passengers and the equipment on board. They give a brief safety lecture before departure, like an airline steward would give regarding oxygen masks and flotation devices. Access by passengers to the Vacc Suits is strictly off limits unless the location they are stored in is unlocked due to an emergency. Similar situation for the rescue bubbles.

Radiation shielding is not neccesarily dependent on density (actually it would be density and thickness and atomic number and geometry).

See Demron for RW example of a wearable hard radiation suit!

(I'm sure this is mostly low-energy gamma, but it exists today!)

BTW: its the electron density (high atomic number elements like lead have more protons, thus more electrons) that's important; and lead can generate x-ray radiation (bremsstrahlung) when exposed to beta (so neutron shielding. i.e. lower atomic number elements may need to be mixed in). Also geometry can be very important (hence, the Demron probably uses 'nanofibers' - didn't read their info).

Even today we have astronauts that have spent over a year in space (Mir) without heavy lead protection. (Granted, they are still in some protection from Earth's thermosphere and nothing says they won't die earlier than otherwise...)

Also, MGT has anti-rad drugs.

Yup though they may move to a more shielded part of the station during a solar storm.

'...and in the event of rapid decompression you all will have 10-15 seconds to understand that you are dead. Thank you, and have a pleasant trip.' -bing-

See Demron for RW example of a wearable hard radiation suit!

Well, it provides 50 % protection from gamma radiation up to 130 KeV,
so it protects against half of the radiation damage caused by radiation
from the very low end of gamma rays, which usually have energies of
a few hundred KeV and go up to 10 MeV - advertisement hype aside,
this suit does not really provide any meaningful protection from hard
radiation at all.

- advertisement hype aside, this suit does not really provide any meaningful protection from hard radiation at all.

(Well the site is obviously advertising hype - its a commercial website - I didn't even read it ) But it does address your statement:

...because there is still no known material that is lightweight and flexible and protects against "hard" radiation (gamma, x-ray ...)

As it does provide protection against gamma and x-rays (as I stated - 'low energy' and 130 KeV is pretty low :roll which your post defined as 'hard'.

Granted - there are varing degrees of 'hard' - such as extremely high energy Cosmic rays or solar flare radiation - but the former is relatively sparce and the later is detectable to a degree (even somewhat predictable - hence, astronauts tend to relocate to better protection).

No amount of shielding is likely to provide 100% protection in any case - some may always get through - and if it hits just the right cell/component cause damage.

Sorry, I did not want to argue, and did not intend to come across that
way.

Ack - not arguing - Clarifying/Sharing - but not arguing!

Happen to be focusing on the Science part of Sci-Fi is all... rust allways has great input and I hope my posts don't come across as being disrespectful of that!

 

[BP]

Not to quibble - but you didn't! (At least not to me.)

Since I was responding, mine probably came across more that way (despite my efforts not to - which takes me some time - your last post beat mine by ten minutes )

If appologies are in order - you certainly have mine - I am sorry if I came across insulting or condescending in any way - be assured it is not my intent!

I'm quite enjoying the discussion - hope you are too!

Yep, of course I am, and I had no problem at all with your post.

LOL

Now you are 'agruing' over who is apologizing first.

I am sure that Grandfather is to blame for this.

Dave, I can see that you have posted something, but for some reason my
browser does not allow me to read it ... 8)

 

[BP]

What? Dave posted something? Must consult with that nice elderly fellow inquiring about possible forum issues...

Well, back near topic - Vacc Suit skill mentions a -2 DM for each level of Vacc Suit skill missing 'for the suit he is wearing'...

• What is this is referring to? A prior post mentioned different TL based requirements - is there a MGT source for this?

If this is for different types of suits (HEV, Combat Armour, etc.), a computer augmented suit would be just the thing.

And does a character with Vacc Suit skill still suffer a penalty in freefall if they lack Zero-G skill?

Dave, I'm not forgetting the 'SciFi

 

[EDG]

Please don't forget the Science Fiction part of any good Science Fiction game.

Sorry, I really hate this sort of statement because there really isn't any "Science" vs "Fiction" in "Science Fiction" - it's all fiction with a scientific basis. Without science there, it's not science fiction - it's just fiction.

That said, there's a range of science fiction that goes from realistic to non-realistic - but to me at least the non-realistic end is "Science Fantasy" - things like Heavy Metal or Star Wars for example, which essentially are traditional fantasy stories with technological trappings (lightsabres instead of swords, the Force instead of magic, etc).

There's also other complications - how "cinematic" the story is, whether things happen for the sake of story instead of because it would happen realistically, etc.

But either way, it's a lot more complicated than just "remember the science in scifi" or "remember the fiction in scifi".

 

[Dave Chase]

EDG, you almost missed the point and just about validated my point at the same time.

I did not seperate the two words but left them together, Science Fiction.

There is hard Science Fiction and there is the high Science Fiction.

LOL

So, thanks for clarifying but look again, I left the 2 words together each time.
