The radiation that does pass through is largely absorbed by ordinary window glass or impurities in the air (e.g., water, dust, and smoke) or is screened by clothing.\r\n\r\n[source](http://www.weatheronline.co.uk/reports/wxfacts/Ultraviolet-radiation.htm)","author":{"url":"https://github.com/originalfoo","@type":"Person","name":"originalfoo"},"datePublished":"2017-07-28T23:22:40.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":7},"url":"https://github.com/58/SensorArray/issues/58"}
