radium was used in luminous paint and for theglow in the dark clock it as it emits radioactive decay that's why its not used in luminous paint now
Radium self luminescent paint hasn't been used in decades since the hazards of it's ionising radiation became widely known. Modern technology of self luminescent paint seems to be based on tritium gas in a similar concept to tritium glow sticks but instead contained within micro particles. These micro particles can be painted on or made in to solid plastic. It is self luminous for 20+ years with a 12 year half-life. The company MPK who invented it calls the technology Litrospheres and also has plans for using it to self power solar panels as an energy source. At the present time this self luminescent paint, plastic or energy source technology has not been made available to the public.
The most common way of making an object glow in the dark is to use chemicals called phosphors to produce light. But I'm not certan that is used in paint.
yes it is in black paint
Elastomeric paint can be applied to a surface that has been previously painted with elastomeric paint. However, with each subsequent layer of the paint, the elasticity of the treatment breaks down considerably.
Radium. I think.
Some tables may be painted with luminous paint. Most are not luminous.
The salt present in luminous paint is typically a phosphorescent material called strontium aluminate.

In modern times, Cobalt-60 is the substance used to make self-luminous paint. Cobalt-60 has replaced Radium's use for the same applications due to Radium's radiation danger.
Naruto just poured paint
The paint is one of the many symbols, in the book, of savagery. If they paint their faces it will be confirmed that they are savage.
