But radiation-powered fluorescence still has its place however, mainly on the hands of certain expensive watches and in military equipment, although these tend to use the safer substance tritium to achieve what radium once did. Thankfully, today, safer alternatives to radium have been found, together with better materials that can soak up the energy in natural light and release it very slowly to produce glow-in-the-dark products that shine for much longer. Scientists subsequently tinkered with the chemicals to produce a range of different colours, but the greens were the easiest for the eye to see, so those were the ones that stuck, together with the myth that radiation glows in the dark! Over-night, quite literally, reliable glow in the dark products were born. This mixture glowed bright green when it was exposed to radioactivity, and adding a small amount of radium to the paint was a cheap way to provide a long-lasting supply of radiation capable of keeping the paint illuminated. So where does the idea that radioactive chemicals glow green actually come from? The most likely source was the development in 1908 of a paint containing zinc sulphide, doped with a small amount of copper. So when they were excited by the radioactive decay of the radium itself, the compounds glowed, producing the fairytale blue light. And as it turns out, Marie Curie's bedside sample contained the compounds radium bromide and uranium chloride, both of which are slightly fluorescent. Most of these excited electrons subsequently fall back to their starting positions, releasing as they do so the extra energy they gained but this time in the form of light, some of which is in the visible part of the spectrum.Ĭhemicals that behave like this, by emitting visible light when they are excited, are referred to as being "fluorescent". When they pass through a material they pull negatively-charged electrons away from the nearest atoms. ![]() These are positively charged and consist of two protons stuck to two neutrons. This is because radium releases alpha particles. Marie described it as "fairy-like", and even kept a tube of radium beside her bed where it presumably functioned as an attractive radioactive night light!īut contrary to popular belief, the glow from the tube wasn't the radiation per-se, but rather the effect it was having on other chemicals that were also present. Chronic radiation-induced dermatitis: Challenges and solutions.Once they began to isolate the metal in reasonable amounts, one of the first things the Curies noticed was that it appeared to emit an attractive blue glow.
