The Cosmic Radiation Station has been operating on a 24-hr basis since November 2000 under the supervision of Prof. Emer. Helen Mavromichalaki in collaboration with international groups. The station is installed in the Department of Physics and due to its location (37.58^o N, 23.47^o E) and its geomagnetic threshold (8.53 GV), is unique in the Balkans and Southeastern Mediterranean. The station records and transmits high-resolution cosmic radiation data (1-hour, 1-min & 1-sec) in "real time".

In 2006, the station was upgraded with the Αthens Neutron Monitor Data Processing Center (ANMODAP), in cooperation with the existing "real-time" neutron monitoring centers at a worldwide scale. The center uses complementary satellite data from the Advanced Composition Explorer (ACE) and Geostationary Operational Environmental Satellites (GOES) missions. Since 2008, it has been active in the effort to create a European Neutron Monitor Database (http://www.nmdb.eu).
