Enamel frit manufacturer talks about the principle of protective enamel radiation protection:

The protective performance of enamel is the ability of the enamel layer to absorb a certain intensity of high-energy radiation. Enamel products made of this kind of enamel can be used for containers and protective devices for storing radioactive substances and chemical reactions involving radioactive substances.

Under the action of ionizing radiation, certain compounds in the chemical composition of protective enamel can produce a photoluminescence effect, which causes a change in the color of the enamel layer on a macroscopic level, which is called "Salenkov effect", that is, under the action of strong radiation, the enamel The electrons inside are in a messy state, and some of them are excluded from their normal positions, causing changes in the properties of the enamel layer. We can use this special property to determine the velocity and direction of certain high-energy radiation.

The color change of lead and barium enamel under the influence of strong radiation is mainly due to the electrons of some coloring elements in the enamel composition being excited and migrating, resulting in a change in the electric price of variable valence ions. This color change is unstable because, when the radiation ceases, the electrons that have migrated return to their original positions, or to more stable positions. This color change caused by high-energy radiation is also affected by temperature. Within a certain range, as the temperature rises, the mobility of electrons increases, which will affect the color change law under radiation.
