Fairly clear now what will destroy our civilization in the long run. And since the physics is universal, it is destroying every other civilization in the universe.
We are not gods and we are not meant to be gods.
At any rate, there are some simple observations one can make to determine if area is safe. Look at what happened in Japan early on. Also just spent some time on the west coast US. Other then seeing a couple of live ewoks and what appeared to be a Viking, there were some radiation clues.
Very low bird population. Could be from less reproduction, illness or the birds are just leaving the area.
Sky is not deep blue. Has a tint due to high altitude particles.
Small animals such as dogs and cats have heart maladies. Radioactive cesium.
Humans developing thyroid issues. Recriticalities ongoing.
Animals behave erratic. We had reports of that in the early Japan no go areas. Mental dysfunction is a symptom of radiation sickness. Causes people to claim exploding buildings are not a problem. lol
One more observation note. This one is kinda shakey with not much support yet. Needs more research.
Basically - Mole size inceases with radiation exposure.
Have one of those ball moles near my nose similar to that ball on Emperor Zeros magnificant nuclear supporting face.
Keep mine small and flat by using anti bacterial ointment occasionally. Please no one tell Obama that.
My mole trippled in size within a few days on the west coast. It also became irritated.
The only reason I mention this is a report from a Japanese refuge family claimed their moles shrunk once they left east Japan.
