Here is an idea I had 6 months ago but forgot to post. Clingfilm will not protect you against radiation, Gamma radiation (the biggest danger) has
little trouble passing through concrete.
It should protect you against radioactivity.
Radioactivity is different to radiation (radiation being an energy beam, rather like light).
In a nuclear accident, radioactivity is the particles that are radioactive. These consist of millions (if not billions) of atoms, that randomly decay.
It is the ability of these particles to float in the wind; then land on people’s soil & property which causes long-term contamination.
However 99% of these particles cannot travel through anything material (because being millions or billions of atoms, they are millions or billions
times too big).
They will make a material radioactive, but only because when their atoms decay, the energy released by these atoms, is enough to
cause the original particle to break down into smaller pieces. These smaller pieces then travel at high speeds, embedding themselves (rather like
bullets) in anything solid they come into contact with. These smaller particles do themselves consists of millions-billions of radioactive atoms,
which continue to randomly decay. That’s how radioactivity spreads.
However the smallest of physical barriers is enough to contain the radioactivity. Nuclear waste barrels are only lined with lead and concrete to
protect the workers against radiation, and to stop Neutron Radiation making other nearby nuclear waste, more dangerous (through something called
Transmutation, which is moving something up or down in the Periodic Table).
But neutron radiation (usually) only makes radioactive elements-isotope’s more radioactive by adding Neutrons to them (like when e.g. depletive
uranium is converted into plutonium). Even then, special conditions (like a nuclear reactor where fuel is in high concentration) are required for much
transmutation to take place. As naturally most neutrons travel either too quickly, or too slowly for much fission-transmutation to take place.
Naturally most things are not radioactive, and if exposed to neutron radiation only short lived radioactive isotope’s (may) be generated.
How Clingfilm Would Help…
During a leak, a house covered with Clingfilm would be as dangerous to live in as one without it, as it’s the radiation that makes the place
dangerous (at any given moment). BUT…
After the nuclear leak has been plugged, a house with Clingfilm over it will be easy to decontaminate. (Almost) none of the roof tiles will have
radioactive particles on them. There will be some radioactive particles that were pushed through the Clingfilm, but 50% flew in the other direction,
most of the other 50% are too big. Consequently...
Clingfilm would REALLY
What it would do is protect important-expensive things where people are also likely to be (like houses or roads) from radioactivity by moving it
elsewhere (i.e. predominantly to wherever the Clingfilm was allowed to drain rain water, -which should be into a hole in the ground filled with
I can only think the Japanese government feared a shortage of plastic sheeting, and therefore did not use it. Either that or: Panic made them
"stupid", and they would therefore now despise admitting, it should have been thought of before. Or: They feared people would take too long to setting
up the clingfilm, and thereby harm themselves. However this would only be applicable to the worst affected areas (wherever they may be).
The point of this thread is that if there was an accident near you, and you want to protect your property, then covering it in something like plastic
that can direct the nasty particles away from your property could make all the difference between barely contaminated, and severely contaminated. The
further the distance they are drained, the less the contaminated. It reduces by the square root of the distance (i.e. double the distance, and receive
75% less radiation than had the distance not being doubled). And if you the drain the particles underground (so the soil acts as a barrier many
hundreds of times more effective than air) then the drop-off will be even more dramatic.
