The deuterium lamp is often used as ultraviolet ray lamp in UV measuring instrument, the measuring accuracy of the instrument has close correlation with the stability of radiation energy.

Researchers suspect that lower temperature, humidity, and ultraviolet light during the winter may increase viral stability; people huddling indoors may facilitate spread as well.

However, some drawbacks exist, such as high temperature agi ng in process of modification, low storage stability and degradation acceleration under ultraviolet.
