Th %PDF-1.6 % When radioactive minerals crystallize, the elements in their structure degrade and break down over time. Examples of gems that may be color-enhanced include beryl, tourmaline, and topaz. While the radiation emitted by these gemstones is not harmful to the human body, it can be detected with a Geiger counter. In apatite and titanite, the natural radioactivity is usually less than the natural background radiation. As shown in figure A-1, there are three types of different natural radioactive decays: alpha (), beta (), and gamma (). Remaining is only the blue topaz in the color "London Blue", which may be radioactive. Gemstone irradiation is a process in which a gemstone is artificially irradiated in order to enhance its optical properties. This is a dangerous mineral, far more dangerous than naturally occurring radioactive substances. Irradiation can be used to change the color of diamonds by emitting electromagnetic radiation. in the mineral. A few tiny traces of radioactive material have appeared on the market for black diamonds and green diamonds now and then. To clarify a common misconception right at the beginning: Not every radioactiv irradiated gemstone becomes radioactive itself as a result of the treatment. In apatite and titanite, the natural radioactivity is usually less than the natural background radiation.
