Solar UV radiation

Background

Exposure to solar ultraviolet (UV) radiation increased in Germany between 2010 and 2019. This change is attributed primarily to declining cloud cover in spring and summer, due in turn to climate change. Elevated UV radiation exposure can increase the risk of diseases such as skin cancer, and damage to the eyes. As a result of climate change, Europe is also experiencing more brief low-ozone events with significantly higher UV radiation levels. The danger of these events is easily underestimated, particularly in the spring, when people have not yet begun taking measures to protect against the sun. Since the risk of skin cancer increases significantly with rising lifetime UV exposure and the population is ageing owing to demographic change, significantly higher numbers of skin cancer cases can be expected in the future. For this reason, the existing protective measures must be stepped up substantially, and new approaches developed and tested.

Work of the KKA at the IFA

The IFA’s Radiation section is also addressing this task. It tests measures and assesses their efficacy against exposure to optical radiation, and provide assistance in the selection of protective components.

A number of projects have been conducted to determine the transmissibility of UV protective clothing and assess the suitability of wearables for use as UV warning systems. A test specification is currently being implemented against which sunscreen products are to be tested and evaluated regarding their suitability for use in occupational scenarios.

Exposure to UV radiation particularly affects workers who must regularly work outdoors. If measures for protection against illnesses and other negative effects of UV radiation are to be effective, their use must not be limited to the workplace; they can also help to reduce risks significantly during leisure hours. In this context, awareness must be raised and information on skin cancer and damage to the eyes caused by exposure to UV radiation must be provided at an early stage in children’s daycare facilities and schools.
