Study Results Force New Australian Antarctic Division UV Exposure Policy
17.11.2009 - Atmosphere & Space, Human Dimension, Antarctic
The results of a new collaborative study by the Australian Antarctic Division and the Australian Radiation Protection and Nuclear Safety Agency show that many who go on Antarctic expeditions receive more than the recommended limit of ultraviolet radiation (UVR) exposure. According to the study, the extended duration of sunlight in Polar Regions along with the hole in the ozone layer over Antarctica and the reflective nature of the ice and water are responsible for the high levels of UVR exposure.
During the austral summers of 2004-05 and 2006-07, subjects in the study were equipped with UVR-sensitive badges for the duration of the working day. These badges showed that, despite wearing sun protection, 80 percent received more UVR-exposure than recommended, with 31% receiving levels more than five times the limit!
With long-term effects including an increased risk of damage to the skin and eyes, the study has lead to a change in the Australian Antarctic Division's exposure policy, starting with the distribution of personal protective equipment to expedition members.
