Ultraviolet radiation and ozone Expansion and compression joints... 

If the most powerful radiation of a mercury lamp, 2536.5 A., were active in ozone formation, the bulk of ozone formation would have to be attributed to this one radiation and ozone formation would also be obtained after insetting the filters. Keeping in mind the behavior of these three filters towards ultraviolet light, the small amount of ozone formed on interposing the filters WG 8 and WG 10 riay be attributed to radiations below 2100 A., for which WG 8 and especially WG 10 a re slightly transparent. Using liquid oxygen and a powerful mercury lamp (440 watts) the results were similar to those just described. ... 

Considerable research was done on the application of an ozone-producing lamp for domestic refrigerators. It was necessary to find a balance between the amount of ultraviolet radiation and ozone so that mold and bacteria on the food and refrigerator wall would be destroyed, while the level of food odors and the transfer of food odors to other foods would be greatly reduced without causing reactions in certain sensitive foods. 

UV hulhs that produce radiation at 184.9 nm generate some quantities of ozone, which, in turn, can provide some oxidation of organic materials. The comhination of UV radiation and ozone produces the hydroxyl free radical, which is a more powerful oxidizing agent than is ozone itself. The 184.9 nm wavelength radiation is not as effective for UV disinfection as the 254 nm wavelength, except by the amount of ozone generated, which will provide some CT value.

UV irradiation of polyolefins may induce changes in their colour and degradation of their physical properties (surface as well as bulk properties). Ozone-generating UV radiation is widely used to clean organic contaminants from various surfaces, while the combined effects of UV radiation and ozone lead to fully oxidised surfaces, increasing the wettability, adhesive properties, and dyeability of polyolefin surfaces. 

Ability of a material to resist all ambient weather conditions. These include changes of temperature, precipitation, effect of wind and humidity, sunlight, oxygen, and other gases, and impurities in the atmosphere, ultraviolet rays, radiation, and ozone.
