Background• “In 1992, Canada developed the UV Index and became the first country in the world to issue nation-wide daily UV forecasts.”
• “The UV Index predicts the maximum amount of UV for the day, at the time it will occur (usually early afternoon).”
![Page 4: Portable UV Monitoring Device](https://reader031.vdocuments.us/reader031/viewer/2022033023/56816262550346895dd2c2f9/html5/thumbnails/4.jpg)
Background• “It is estimated that more than 76,000 new cases of skin cancers were diagnosed across Canada in 2004.”
• “UVB damage is cumulative. However, diligent use of sunscreens during the first 18 years of life could reduce the lifetime incidence of non-melanoma skin cancers by 78%.”
