During WWII there was a substance available on Navy ships,

seen in a dark room.

Is there anything like that available today - in either
paint or tape form - that one can use for such purposes in
the home?


Historical Note:

In first part of the last century, the military used radium to make
glow-in-the-dark hands and numbers on government issue watches. The
workers who applied this paint were not told of any dangers and would
do things like lick the brushes before applying the paint to the
dials. Many, if not all of them came down with radiation poisoning
and the who incident became a famous test case about whether workers
could sue their employers for ruining their health.

One benefit of the radium though... The watches did not need to be
"charged" under light to stay luminous.

Many modern luminous paints require this "light charge" in order to
work properly.

Google or Wikepedia "Radium Girls" for the complete story.

Personal Note - I remember my cousin showing us the radioactive dimes
he purchased from the tourist store at Oak Ridge, TN during the early
1960's. That couldn't have been good either...
