corner of a room in Agia Paraskevi, Greece, where a whiteboard is mounted on the wall. The whiteboard is green and is covered in white chalk markings. These markings include numbers, symbols, a line graph, and some Greek text. The numbers and symbols appear to represent some kind of data. A radiation warning sign with a yellow background and a black radiation symbol is attached to the wall to the left of the whiteboard. The sign is in Greek and English and reads "HIGH INTENSITY RADIATION AREA." Below the sign is a smaller sign with a blue background and white text. The walls are painted a light gray. There are no people visible in the image. The room appears to be a laboratory or a workspace.
