Uridine as a non-toxic actinometer for UV-C treatment: influence of temperature and concentration

Jaayke L. Fiege et al.

Summary: UV-C treatment is an effective method for microbial inactivation in the food industry. A reliable and non-toxic photochemical actinometer is needed to test and monitor different UV-C reactor designs. Uridine solution has been found to be a reliable actinometer and can be used as a non-toxic dosimeter for UV-C systems.

Ultraviolet actinometry - Determination of the incident photon flux and quantum yields for photochemical systems using low-pressure and ultraviolet light-emitting diode light sources

Dana Pousty et al.

Summary: The study focuses on accurately assessing the interaction of light with photochemical and photobiological systems, specifically in terms of incident photon flux and quantum yields. The research demonstrates the calibration of a spectroradiometer using different actinometers and investigates whether UV-LEDs should be considered as monochromatic or polychromatic light sources. The findings indicate consistency in quantum yields between well-researched actinometers and no significant differences between monochromatic and polychromatic analysis.
