article_snippet.sent: But for people who fly frequently, cosmic radiation can increase this exposure significantly.
article_snippet.sent: Since 1997, PTB has studied the cosmic radiation at typical flight altitudes and used this to calculate radiation levels.
article_snippet.sent: Experts studied the average radiation of someone in the US at flight altitudes between 5 miles (8km) and 7.5 miles (12km) worldwide between 1997 and 2006.
article_snippet.sent: Airline pilots are at risk of deadly skin cancer because Airline pilots are exposed to cockpit radiation similar to levels from tanning beds.
article_snippet.sent: Pilots flying for an hour at 30,000ft get the same amount of radiation as 20 minutes on a tanning bed.
article_snippet.sent: And researchers believe the levels could be higher when pilots are flying over thick clouds and snow fields, which can reflect UV radiation .
article_snippet.sent: A team from the University of California measured the amount of UV radiation in airplane cockpits during flights.
article_snippet.sent: The cockpit radiation was measured in the pilot seat of a general aviation turboprop airplane through the acrylic plastic windshield at ground level and at various heights above sea level.
article_snippet.sent: Of The cockpit radiation, around nine per cent comes from cosmic radiation.
article_snippet.sent: Exposure to this kind of radiation is more significant at higher latitudes and near the magnetic poles, and many planes take polar routes to cut journey times.
article_snippet.sent: Last year researchers from the University of California found that pilots flying for an hour at 30,000ft get the same amount of radiation as 20 minutes on a tanning bed.
article_snippet.sent: And researchers believe the levels could be higher when pilots are flying over thick clouds and snow fields, which can reflect UV radiation .
highlights_snippet.sent: This includes exposure from medical examinations, changes in a person's location and flights .
