Sometimes shining a light on a nuclear problem just makes things worse

Radiotherapy systems

I was servicing a recently installed system at a hospital and they mentioned it would trip if they used the rotation option as part of the treatment. It was only in a small section of the arc but nothing was obvious until I noticed a gap between two panels with a ribbon cable behind which carried various monitor signals. Popped down the local Spar shop to get some tinfoil which I wrapped round the cable and then added an earth wire to and as if by magic, all now OK. A proper sheiled cable was sent to replace my homebrew efforts but I can honestly say it was no better and looked boring in comparison.
