Radioactive Decay For night lighting ???

Using the weak force to light the center divider on streets. To light
poles. To add to paint so cars glow.(orange). Yes there was a time you
could buy paint that glowed in the dark. It was outlawed,but could we
block out the harmful radiation and just let light photons through?
Most accidence happen because we have big troubles seeing when the Sun
has gone down. Best to keep in mind radioactive energy is just about
free. We spend a lot of money producing light. Bert
