Greetings,
it comes as no surprise to find that TEPCO, the Japanese
company mismanaging the Fukushima nuclear power plant
clean up is both not coping and lying to the public. First
they had to come clean about pumping 300 tonnes of
irradiated water into the sea everyday and these last few
days have to admit that if you stand next to one of the
thousands of irradiated water storage tanks you would be
dead within two hours. Fortunately the workers there are
quitting rapidly so we have no need to worry about their
health. We can be further reassured by TEPCO informing
us that the beta rays being emitted can be blocked by
common or garden aluminum foil. Thus anyone who is
traveling in the area, or indeed planning on attending the
Olympics if they are held in Tokyo, would be able to take
full advantage of all the beautiful scenery, secure in the
knowledge that not only are they wearing an aluminum
foil suit that can chucked away after one days`s use and
replaced at a pittance. But also have in their bag an
aluminum foil hood. Should the wind suddenly change
direction and those rads shoot up one can quickly don this
hood and carry on with whatever one pleases.
So much more convenient than carrying a roll of aluminum
with you to wrap around your extremities.

Baked. Almost all "radiation suits" are single use. |

Irradiating ordinary water has very little effect on it. And it doesn't become dangerously radioactive. |
|
| |
// the beta rays being emitted can be blocked by common or garden aluminum foil. // |
|
| |
This is true. The danger is not directly from Beta radiation. The danger is from inhaling or ingesting Beta-emitting nuclides. A respirator is far more important than a suit; the suit just needs to stop the contamination from getting on your skin. And even then, simple washing is very effective at removing it. |
|
| |
// carrying a roll of aluminum with you // |
|
| |
I only grab mine when my hat needs maintenance. |
|
| |
Are we sure it's beta radiation only? |
|
| |
Well they're lying again it seems because it apparently takes several mm of Al to stop beta particles [link]. That would make for a heavy suit and an expensive disposable one. |
|
| |
In general, paper will stop Alpha radiation, and
aluminum foil or a heavy coat will stop Beta
radiation. There isn't anything you can wear that
will do a decent job of stopping Gamma radiation. |
|
| |
As [8th of 7] indicated, the main goal of a
radiation suit is to prevent radioactive particles
(like dust that contains atoms that are emitting
Alpha, Beta or Gamma radiation) from becoming
physically intimate with your body. |
|
| |
NONE of those three types of radiation are
themselves ordinarily able to make something
radioactive. It is the radioactive particles that are
already emitting dangerous rays that you have to
avoid; thus, again, the purpose of the radiation
suit is to keep you isolated from those particles. |
|
| |
There is a fourth type of radiation, Neutron
radiation, that is both very dangerous and very
rare. Extremely few types of radioactive atoms
release a neutron. (For example, Uranium-235 can,
via "spontaneous fission".) Neutron radiation CAN
make other things radioactive; that's what makes
it dangerous. |
|
| |
But, generally speaking, you don't have to worry
about Neutron radiation anywhere outside a
functioning nuclear reactor core (and if you were
in such a place, the Gamma radiation would
probably kill you first). Staying away from such
places is, of course, another definition of
"isolation". |
|
| |
//Are we sure it's beta radiation only?// No. They just measured 1.8Sv near the water tanks. That is a very significant amount of ionizing radiation and nothing wearable would help in the slightest. I also have to say [marked-for-deletion] bad science because aluminum foil will not stop Beta radiation. Several mm of aluminum sounds more likely and I know for a fact that Beta can pass through a thin piece of sheet steel. There are suits that can stop Alpha and Beta, which I linked, but they're made of thick rubber. |
|
| |
You could always go for the 70's science fiction look
and wear Perspex - a few mm stops beta more or less
completely. On the downside, it does tend to
create Brehmsstrahlung gamma radiation, though. |
|

Neoprene sheet, loaded with lead dust, bloody heavy and uncomfortable to wear. |
|
| |
Gold, now. Just as heavy, but more stylish. Nuclear bling, whatever next ? |
|
| |
// the Gamma radiation would probably kill you first // |
|
| |
THe thermal radiation would probably kill you first, if you didn't already succumb to being sumbmerged in very hot liquid coolant under extreme pressure. |
|
| |
// an expensive disposable one // |
|
| |
Expensive compared to what, exactly ? The cost of your medical treatment and subsequent funeral ? |
|
| |
//Expensive compared to what, exactly ?// |
|
| |
Er, a roll of aluminum foil? |
|
| |
But it has already been established (see above) that aluminium foil will only protect you from the CIA Brane Ray Machine, not Beta radiation ... |
|
| |
As for the radiation suit, it's beta than nothing. Well, someone had to say it. |
|
| |
//you would be dead within two hours. |
|
| |
I think that eventually panned out to be "four hours if you wanted a fatal dosage" but presumably it takes a lot longer than that to actually die, so bit of misleading claims. |
|
| |
NB might be back in that neck of the woods in three weeks or so. Just read my posts through lead glass and you should be ok. |
|
| |
// Well, someone had to say it. // |
|
| |
Perhaps. But it places you in the same category as, for instance, someone who says, "Oooh, let's annex Austria, and the Sudetenland ... and then maybe invade Poland ?" |
|
| |
// it takes a lot longer than that to actually die // |
|
| |
Unfortunately, yes. Quite a lot longer. But death does inevitably occur, and the interval between exposure and demise is extremely unpleasant for the victim. |
|
| |
//exposure and demise is extremely unpleasant for the victim |
|
| |
Er..is there any kind of physical ailment that gives the victim a wonderful couple of weeks, possibly in the Dordogne? |
|
| |
A prolonged moderate overdose of opiates ? |
|
| |
//moderate overdose of opiates |
|
| |
Well that would certainly explain some of either your or my posts. It only remains to work out which one of us.... |
|
| |
Interestingly, aluminium is one of the substances rendered radioactive by exposure to neutron radiation (but water is not). In fact, "One way to demonstrate that nuclear fusion has occurred inside a fusor device is to use a Geiger counter to measure the radioactivity that is produced from a sheet of aluminum foil."
