(27,509 posts)Radiation can be scattered, reflected, refracted, and diffracted.
Radiation can also be carried by radioactive isotopes.
Global warming is caused by greenhouse gasses reflecting infrared radiation back to earth.
The reason the sky is blue instead of black is because blue frequencies are scattered by the atmosphere.
If you remember the Apollo lunar photos, the sky was black, and all shadows were black.
That's because there was no atmosphere to scatter light across the sky and into shadows.
Sunlight fills your house during the daytime because it is scattered by the atmosphere and reflected by nearby structures into your windows, then it is reflected off the walls, ceilings, and floors inside your house.
The same thing happens with radiation from a nuclear plant - it's called "skyshine"
When a child puts a stick into water, he asks why does the stick bend?
The stick doesn't bend - the light from the stick bends.
This is refraction, and it happens at the spent fuel pools too.
Different frequencies of light refract at different angles, that's how prisms and rainbows work.
The single slit and double slit experiments are examples of diffraction.
Radioactive isotopes don't go in a straight line, and they release radiation everywhere they go.
If the source of the radioactive isotopes is Fukushima,
then it's not incorrect to say that the radiation came from Fukushima.
