One of these is radiation: an invisible danger but one that can cause serious harm to space travellers. A new gadget has been developed to help us better understand this threat.<\/p>\n<\/div>\n<p>Radiation comes from different places in space, such as the Sun and distant dying stars. Radiation damages the cells that our bodies are made from, and can cause severe illnesses \u2013 even death. Here on the surface of planet Earth we are protected from this radiation by our planet\u2019s magnetic field. This acts like a shield and keeps us safe. But astronauts in space are at a higher risk of exposure.<\/p>\n<figure class=\"wp-block-image size-large\" data-width=\"1280\" data-credit=\"ESA\" data-detail-url=\"https:\/\/www.esa.int\/ESA_Multimedia\/Images\/2016\/07\/EuCPAD_units_will_be_worn_by_astronauts\" data-licence=\"ESA Standard Licence\" data-licence-url=\"https:\/\/www.esa.int\/ESA_Multimedia\/Terms_and_conditions_of_use_of_images_and_videos_available_on_the_esa_website\"><img decoding=\"async\" loading=\"lazy\" style=\"max-width:100%;height:auto\" src=\"https:\/\/www.esa.int\/var\/esa\/storage\/images\/esa_multimedia\/images\/2016\/07\/eucpad_units_will_be_worn_by_astronauts\/17911565-2-eng-GB\/EuCPAD_units_will_be_worn_by_astronauts.jpg\" alt=\"EuCPAD units will be worn by astronauts\"><figcaption>EuCPAD units will be worn by astronauts<\/figcaption><\/figure>\n<p>Astronauts already wear sensors that add up their total radiation exposure over time. But the information on them can only be read when they come back to Earth, in a special lab.<\/p>\n<p>To give a more accurate picture, scientists and engineers have developed the European Crew Personal Active Dosimter \u2013 EuCPAD for short. A monitor about the size of a smartphone records its wearer\u2019s exposure on a continuous basis.<\/p>\n<p>Then astronauts can plug them into a bigger device like a smartphone dock, to recharge their battery and download their results. Astronauts and researchers down on the ground can then gain regular updates on the radiation environment: are some parts of their spacecraft better shielded than others?<\/p>\n<figure class=\"wp-block-image size-large\" data-width=\"1279\" data-credit=\"ESA\" data-detail-url=\"https:\/\/www.esa.int\/ESA_Multimedia\/Images\/2016\/07\/ESA_astronaut_Andreas_Mogensen_has_tested_a_EuCPAD\" data-licence=\"ESA Standard Licence\" data-licence-url=\"https:\/\/www.esa.int\/ESA_Multimedia\/Terms_and_conditions_of_use_of_images_and_videos_available_on_the_esa_website\"><img decoding=\"async\" loading=\"lazy\" style=\"max-width:100%;height:auto\" src=\"https:\/\/www.esa.int\/var\/esa\/storage\/images\/esa_multimedia\/images\/2016\/07\/esa_astronaut_andreas_mogensen_has_tested_a_eucpad\/17883954-2-eng-GB\/ESA_astronaut_Andreas_Mogensen_has_tested_a_EuCPAD.jpg\" alt=\"ESA astronaut Andreas Mogensen has tested a EuCPAD\"><figcaption>ESA astronaut Andreas Mogensen has tested a EuCPAD<\/figcaption><\/figure>\n<p>A EuCPAD monitor was tested last September by ESA astronaut Andreas Mogensen.
