Rad resistant E-Stop push button
Rad resistant E-Stop push button
(OP)
This may sound silly, but I need to find an E-Stop push button switch that can handle very high radiation doses. Doses of 40 Mrad can be expected.
Does anyone know of anything that can withstand this? Any information (no matter how insignificant you think it may be) is greatly appreciated.
Thanks,
Rob

If not they can perform new testing for you though it will be costly.
Good luck!!!

Never mind if the E-Stop Button can stand the dose, what about the person who will have to press it!
If the dose is 40 Mrad, ie 40 x 10^6 rads, then that is WAY past the lethal dose.
(in UK speak 1 rad = 0.01 Gray, LD50 = 3-5 Grays)

In terms of the application, it is really quite silly. The switch will be located on a power reactor fuelling machine. The radiation doses are very high (I forget the numbers, but they were very lethal) and no operator would be in the reactor vault when the machine was running. However, the customer wanted it for when the machine was out for servicing and testing. Why the supplied detachable "dead man" switch was not sufficient is beyond me...
