Windscale nuclear reactor (UK): 7 October 1957. A fire in the graphite-core reactor, in Cumbria, results in a limited release of radioactivity (INES Level 5). The sale of milk from nearby farms is banned for a month. The reactor cannot be salvaged and is buried in concrete.
1 Bottom of foot pain may occur if the sciatic nerveâs S1 spinal nerve root is affected. 2  Typical symptoms of pain in the bottom of the foot may include weakness in the gastonemius muscle, making it hard to walk on the tiptoes, raise the heel off the ground, or even complete everyday activities like walking or driving.
This nerve runs from the lower part of the spinal cord, down the back of the leg, to the foot. Injury to or pressure on the sciatic nerve can cause the characteristic pain of sciatica: a sharp or burning pain that radiates from the lower back or hip, possibly following the path of the sciatic nerve to the foot.
