11. Also, the material that the bulb is made of can absorb some of the germicidal rays. 12. :According to the Silver article, silver has germicidal effects and kills many microbial organisms in vitro. 13. For human beings, skin exposure to germicidal wavelengths of UV light can produce rapid sunburn and skin cancer. 14. The water is cleaned and sanitized through the use of chlorine, filtration and an ultraviolet germicidal irradiation system. 15. It is also released over time in the affected area to prolong its germicidal action, making wound treatment painless. 16. The UV dose is the amount of germicidal UV energy absorbed by a microbial population over a period of time. 17. The most common form of germicidal lamp looks similar to an ordinary fluorescent lamp but the tube contains no fluorescent phosphor. 18. Chlorine can also be used, but its germicidal activity varies with the pH, temperature and organic content of the water. 19. A "'germicidal lamp "'is a special type of lamp which produces ultraviolet ( UVC ) light. 20. The meteorite was then soaked in hydrogen peroxide to wash off dirt, held briefly over a flame and plunged into a germicidal solution.
