The slide rule is operated by rotating the large disc by the edges. The first side displays radii of destruction of various structures and vehicles. The other side allows to calculate the size and magnitude of nuclear fallout. I'm not sure how to use the smaller slide rule in the centre. It would be great if someone could share some more info about this device.
